Methylene Blue Benefits.

Methylene blue, known for its vivid blue hue, is a synthetic compound that has been a staple in medical practice for over a century. Initially created as a textile dye in the late 19th century, it quickly found a role in healthcare due to its versatile medical properties. It has been used effectively as an antimalarial agent, in treating methemoglobinemia, and as a surgical dye to help identify anatomical structures.

Contemporary studies explore methylene blue's potential as a neuroprotective agent and its ability to enhance mitochondrial function. These qualities may offer a range of health advantages, marking methylene blue as a compound of significant medical interest. However, its impact on brain chemistry is complex, and potential side effects include alterations in neurotransmitter levels, which can affect mood and cognitive function.

What is Methylene Blue?

Methylene blue is a chemical compound that stands out for its particular molecular configuration, which renders it useful in the medical field. It is a dark green powder in its dry state, but when dissolved in water, it transforms into a vivid blue solution. This stark blue hue has practical applications in medical settings, where it can be used to clearly delineate tissues and bodily fluids during procedures.

In addition to its visual utility, methylene blue shares functional similarities with hemoglobin—the vital protein in blood cells that carries oxygen throughout the body. Its ability to mimic hemoglobin's oxygen-transporting role enables methylene blue to effectively treat a range of medical issues.

Health Benefits of Methylene Blue

In the following sections, we will unveil methylene blue's remarkable potential as a therapeutic agent, shedding light on its ability to provide significant benefits for individuals grappling with a diverse range of medical conditions.

Antidepressant Properties

One of the most promising benefits of methylene blue is its potential as an antidepressant. Studies have shown that methylene blue can significantly reduce symptoms of depression in patients, even in those who have not responded well to traditional antidepressant medications. (1)

Methylene blue increases the activity of specific neurotransmitters in the brain, including serotonin and norepinephrine, which are critical in regulating mood. (2)

Anti-Inflammatory Effects

Methylene blue has also been shown to have potent anti-inflammatory properties. Inflammation is a common factor in many chronic diseases, including Alzheimer's, cancer, and heart disease. Methylene blue may help prevent or treat these conditions by reducing inflammation. A study conducted on mice found that methylene blue significantly reduced inflammation in the brain and prevented cognitive decline. (3)

Alzheimer's Disease

Alzheimer's disease is a progressive brain disorder affecting millions worldwide. Recent studies have shown that methylene blue may effectively treat Alzheimer's disease by reducing the buildup of toxic proteins in the brain. (4)

These toxic proteins, amyloid plaques, and tau tangles are believed to be the underlying cause of Alzheimer's disease. By reducing the buildup of these proteins, methylene blue may be able to slow or even halt the progression of the disease.

Sepsis Management

Sepsis is a potentially life-threatening condition caused by the body's immune system overreacting to an infection. It can lead to organ failure and even death. Methylene blue effectively treats sepsis by reducing inflammation and improving blood flow. (5) One study found that methylene blue significantly improved survival rates in patients with sepsis.

Parkinson's Disease Treatment

Parkinson's disease is a neurodegenerative disorder that affects movement, and the death of dopamine-producing neurons in the brain causes it. A recent study found that methylene blue can protect these neurons and prevent their death, potentially slowing or halting the progression of Parkinson's disease. (6)

Malaria Treatment

Malaria is a life-threatening disease caused by a parasite that infects red blood cells. Methylene blue is effective in treating malaria, as it can kill the parasite that causes the disease. (7)

Methemoglobinemia Therapy

Methemoglobinemia is a rare blood disorder in which the blood contains too much methemoglobin, a form of hemoglobin that cannot transport oxygen effectively. Methylene blue treats methemoglobinemia by converting the excess methemoglobin to its normal form, allowing it to transport oxygen properly. (8)

Cyanide Poisoning

Cyanide is a deadly poison found in various industrial chemicals and certain foods. Methylene blue can treat cyanide poisoning by binding to it and converting it into a less toxic form. (9)

Acute Respiratory Distress Syndrome Management

ARDS is a severe respiratory condition that can occur in people with certain medical conditions, such as pneumonia or sepsis. A study found that methylene blue can improve lung function and reduce inflammation in patients with ARDS. (10)

Neurological Disorder Treatments

Methylene blue has been found to potentially treat various neurological disorders, such as multiple sclerosis, spinal cord injury, and stroke. It may help protect neurons from damage and reduce inflammation, potentially improving the outcome of these conditions. (11)

Radiation-Induced Tissue Injury Management

Radiation therapy is a standard cancer treatment, but it can cause damage to surrounding healthy tissue. Methylene blue has been found to protect against radiation-induced tissue injury by reducing oxidative stress and inflammation. (12)


Diabetes is a chronic disease characterized by high blood sugar levels. In animal studies, methylene blue has been found to improve insulin sensitivity and reduce blood sugar levels. (13)

Ulcer Treatment

Ulcers are painful sores that can develop in the digestive tract. Methylene blue has been found to reduce ulcer formation by inhibiting the growth of Helicobacter pylori, a bacterium often associated with ulcers. (14)

Skin Conditions

Methylene blue can potentially treat various skin conditions, such as psoriasis (15) and eczema. It may help reduce inflammation and improve skin barrier function, potentially improving symptoms.

Antiviral Properties

Methylene blue has been found to have antiviral properties, particularly against viruses such as dengue and Zika. It has been shown to inhibit viral replication and reduce the severity of symptoms in animal studies. (16)

Heart Disease Management

Methylene blue has been found to improve cardiac function and reduce damage to heart tissue in animal studies of heart disease. It may do this by reducing oxidative stress and inflammation. (17)

Wound Healing

Methylene blue has been found to promote wound healing, as it may help reduce inflammation and promote the growth of new blood vessels. (18)

Liver Disease Treatment

Methylene blue has been found to potentially treat various forms of liver disease, such as liver fibrosis and fatty liver disease. It may do this by reducing inflammation and oxidative stress in the liver. (19)

Alcohol Use Disorder Treatment

Methylene blue has been found to reduce the severity of alcohol withdrawal symptoms in animal studies. It may do this by regulating the brain's reward system and reducing oxidative stress. (20)

Inflammatory Bowel Disease Management

IBD is a chronic inflammatory disorder of the digestive tract that includes Crohn's disease and ulcerative colitis. Methylene blue has been found to improve symptoms of IBD in animal studies by reducing inflammation and oxidative stress. (21)

Bone Loss Prevention

Methylene blue has been found to promote bone formation and reduce bone loss in animal studies of osteoporosis. It may do this by promoting the differentiation of bone cells and reducing inflammation. (22)


Tinnitus is characterized by a ringing or buzzing sound in the ears. Methylene blue has been found to reduce tinnitus severity in animal studies by reducing oxidative stress and inflammation in the auditory system. (23)

Chemotherapy-Induced Neuropathy

Chemotherapy-induced neuropathy is a common side effect of cancer treatment that can cause pain, numbness, and tingling in the extremities. Methylene blue has been found to reduce neuropathic pain and improve nerve function in animal studies. (24)

Glaucoma Treatment

Glaucoma is a group of eye diseases that can cause vision loss and blindness. Methylene blue has been found to reduce intraocular pressure, which can help prevent damage to the optic nerve in glaucoma patients. (25)

Hair Loss Management

Methylene blue has been found to promote hair growth in animal studies. It may do this by increasing blood flow to the hair follicles and promoting the proliferation of hair cells. (26)


Depression is a common symptom of Parkinson's disease. Methylene blue has been found to improve depressive symptoms in patients with Parkinson's disease in a small clinical trial. (27)


Methylene blue has been found to reduce seizure frequency in animal models of epilepsy. It may do this by increasing levels of the neurotransmitter GABA and reducing oxidative stress in the brain. (28)

Stroke Management

A stroke is a medical emergency that can cause long-term disability and death. Methylene blue has been found to protect against brain damage and reduce neurological deficits in animal models of stroke. (29)


Osteoarthritis is a degenerative joint disease that causes pain and stiffness. Methylene blue has been found to reduce joint inflammation and cartilage damage in animal models of osteoarthritis. (30)

Methylene Blue Dosage and Dilution Instructions

Understanding the proper dosage and dilution instructions is essential when considering methylene blue supplementation. Here are detailed guidelines, including important warnings about potential side effects:

  1. Consult a healthcare professional: Before starting any new supplement, it is crucial to consult with a healthcare professional. They can help determine if methylene blue is appropriate for your needs and provide personalized dosage recommendations based on your medical history and current medications. This is particularly important given the potent effects of methylene blue and the risk of serious side effects.

  2. Obtain a high-quality methylene blue supplement: Ensure you purchase a pharmaceutical-grade one from a reputable source. This will help guarantee its purity and potency, as low-quality supplements may contain impurities or insufficient active compound concentrations.

  3. Prepare the methylene blue solution: Methylene blue is a powder or a concentrated liquid. To prepare a solution, carefully follow the instructions from the manufacturer or your healthcare professional. Generally, following the recommended dilution ratios, you will need to dilute the methylene blue in distilled water or another suitable solvent. Ensure that you mix the solution well to achieve a homogenous mixture. Note: Earth Clinic readers have provided insight on dilution in the posts below.

  4. Determine the appropriate dosage: The optimal dosage of methylene blue can vary depending on the individual and the intended purpose. Dosages can range from low microgram amounts (for cognitive enhancement or as an antioxidant) to higher milligram amounts (for treating specific medical conditions). Always follow the dosage recommendations provided by your healthcare professional.

    Important Warning: Even small doses can have potent effects. For example, some individuals have experienced serious side effects with as little as 3 drops in water, despite instructions recommending 20 drops. Start with the lowest possible dose and monitor your reaction closely.

  5. Administer methylene blue: Methylene blue can be administered orally, intravenously, or topically, depending on the intended use. Use a dropper or a graduated syringe to measure the correct dosage for oral administration. Drink the solution on an empty stomach, as food may interfere with its absorption. For intravenous or topical administration, follow the instructions provided by your healthcare professional.

  6. Monitor for side effects: While methylene blue is generally considered safe when taken at appropriate dosages, it can cause side effects in some individuals. Potential side effects may include gastrointestinal upset, dizziness, headache, or skin irritation. More severe side effects can include alterations in brain chemistry, leading to symptoms such as confusion, agitation, or mood changes.

  7. Adjust the dosage as needed: Your healthcare professional may recommend adjusting your methylene blue dosage over time based on your response to the supplement. Be sure to follow their guidance and communicate any concerns or changes in your condition.

Methylene blue offers a variety of potential health benefits, but it is essential to take it correctly to ensure safety and efficacy. Following the appropriate dosage and dilution instructions and consulting with a healthcare professional can optimize the potential benefits of methylene blue supplementation while minimizing the risk of adverse effects.

Proceed With Caution: Methylene Blue's Potent MAO Inhibition and Potential Drug Interactions

While promising as a therapeutic agent, Methylene Blue is a potent MAO inhibitor and can interact with various medications, potentially leading to contraindications.32

MAO inhibitors work by blocking the action of monoamine oxidase, an enzyme that breaks down neurotransmitters such as serotonin, dopamine, and norepinephrine. This inhibition can enhance the levels of these neurotransmitters, potentially leading to beneficial effects. However, it can also cause severe side effects and interactions with other medications.

One of the most serious risks associated with methylene blue is serotonin syndrome, a potentially life-threatening condition caused by an excess of serotonin in the brain. Symptoms of serotonin syndrome can range from mild (shivering and diarrhea) to severe (muscle rigidity, fever, and seizures) and may require hospitalization. This condition can occur when methylene blue is combined with other medications that increase serotonin levels, such as certain antidepressants (SSRIs, SNRIs), pain medications (tramadol), and other MAO inhibitors.

Given the risk of severe drug interactions, it is essential to proceed with caution when considering the use of methylene blue. Many medical professionals may not be fully aware of its MAO inhibiting properties, making it crucial for patients to consult their healthcare provider. A thorough discussion of your medical history and current medications is necessary to ensure an informed decision and to minimize the risk of complications.

Additionally, it is important to monitor for any adverse reactions if methylene blue is prescribed, especially during the initial phase of treatment. Regular follow-up appointments and open communication with your healthcare provider can help manage any potential risks. Always inform your provider of all the medications, supplements, and herbs you are taking to avoid contraindications and ensure safe use of methylene blue.


In summary, methylene blue stands out as a highly versatile and potent medicinal agent with a range of promising applications. Its health benefits span from acting as an antidepressant to having anti-inflammatory properties and playing a potential role in treating neurodegenerative diseases such as Alzheimer's and Parkinson's. This compound has also proven effective in managing various other conditions like sepsis, malaria, methemoglobinemia, and heart disease, showcasing its multifaceted utility in medical treatments.

Beyond its established uses, ongoing research explores methylene blue's potential to address other health issues, including diabetes, ulcers, skin conditions, and inflammatory bowel disease. As research progresses, the scope of methylene blue in developing new therapeutic approaches and treatment strategies for a wide array of diseases is expected to broaden.

Posted by Bill (Philippines) on 06/15/2023

I've been experimenting with Methylene Blue(MB) for many years and I thought it might be useful to clear up some of the unfortunate myths that have arisen concerning MB usage.So this post should hopefully help to clarify many apparently confusing aspects when someone supplements MB for the first time for whatever reason.

First, because there seems to be so much dosage confusion about MB percentage strength and number of drops used, I'm going to use a completely different quantitative method that determines how many milligrams or how many drops to supplement MB with water. There has been much of confusion over this.

But first some information that I have found to be extremely useful in helping to more fully understand the effective dosage amounts of MB needed for particular ailments :

1 drop of 1% Methylene Blue contains 0.5 mgs of MB.

1 drop of 0.1% Methylene Blue contains 0.05 mgs of MB

1 drop pf 2.33% Methylene Blue(Aquarium version ) contains 1 mg(approx.)

A half teaspoon of MB is 40 drops.

A full teaspoon of MB is 80 drops.

So armed with the above helpful definitions, I will now only describe MB dosages in milligram amounts only. Doing it this way eliminates all the confusion(and myths) of how you should use 0.1% or 1% or 2.33% MB. After all, it's the dose of MB powder in water that you supplement that is all-important -- not the percentage of MB in your dropper bottle. Right?

Ted from Bangkok has also maintained in his MB posts that supplementing the cheaper aquarium version of Methylene Blue is certainly good enough and pure enough for supplementing in humans. But if that last statement makes some readers balk in fear of "heavy metal impurites" then it's perhaps also useful to appreciate that fish live and breath in water and humans breath air. But water is a much more dense medium than air. And that means that fish are much more sensitive to poisons, heavy metals etc in their water than humans are. So if the aquarium version of MB is good enough for the more sensitive fish then it should certainly follow that aquarium MB is pure enough for us humans as well. And that's also why I've been using the aquarium version of MB, without any problems whatsoever, for over 10 years now.

Other things to remember about MB is that low MB dosages will be good enough to help give you energy and to help MB act as both an antioxidant and antimicrobial for the brain, thus helping to increase and maintain mental cognition as well as helping to prevent dementia(Alzheimer's Disease, Parkinson's Disease etc). However, much larger doses of MB will be required to kill viruses or bacteria, cure malaria, kill fungus, kill parasites, treat Methemoglobinemia, help remove blood clots etc.

But what do I mean when I say take a low dose of MB in water? -- And here is where all the confusion happens. I've read that for some people 2 drops of 1% MB(which is equivalent to 1 mg MB powder on water) is enough to fully energize them. I've also read where other people need to take as much as 16 mgs or even 100 mgs of MB(which is still a low dose for MB) to get energized. The point that I'm making here is that you will normally always have to find your own MB dose that works for you personally.

My own dose, which suits me for getting more energy and obtaining the cognitive benefits from using MB, is based on Dr Golwalkar's method that he has been using over the years to treat and cure both tuberculosis and COVID-19. He uses a teaspoon of 0.1% Methylene Blue for nebulizing(which is equivalent to 4 mgs MB powder in water) and he also recommends taking a half teaspoon of 0.1% MB orally as a sub-lingual dose(which is equivalent to taking 2 mgs MB powder in water).

My own everyday MB dose is slightly different to Dr Golwalkar's sub-lingual dose. I just add half a tablespoon of water to a small empty glass and then add 4 drops of 2.33% Methylene blue(which is equivalent to taking approximately 4 mgs of MB powder) and supplement that twice a day. But I have also taken the equivalent of more that 25 mg MB powder per day without a problem. I would also recommend using Dr Golwalker's recommendation of using 5 mls or 1 teaspoon of 0.1% MB(which is equivalent to 4 mgs MB powder in water) in a nebulizer two or three times a day when infected with COVID-19.

Some more MB facts for you. When you supplement Methylene Blue then between 75% and 80% of the MB taken orally is directly and quickly absorbed into the blood. Methylene Blue has a half-life in the human body of about 6 hours. That means that half the amount of MB that you supplemented will still be in your body after 6 hours. It's for reason of this persistence of MB in the body that I would at least advise that for low dose MB you should at least take one day off a week to reset your system and get rid of all the MB in your body.

I've also found an easy way of converting Methylene Blue from its blue oxidant form to its colorless reduced form. I will, for instance, add my 4 drops of Methylene Blue to a little water in a glass for sublingual supplementation. Then I would add a very small amount -- a tiny amount!! -- of Ascorbic Acid to the MB and walk outside and let the sunlight quickly convert the blue oxidant form of MB to it's colorless reduced form and just take it like that without giving me a blue mouth. I've also used the reduced or colorless MB form on skin problems without any blue coloring occurring. It works well and MB is also rapidly and easily absorbed into the skin.

Thank you for your detailed information. I have been taking it daily with one day off for the past month. For how long should I continue to take it?


Hi Bobby,

Methylene Blue(MB) has been used as a blue dye and as a standard treatment for malaria for over 120 years. During the Vietnam war MB powder was used by the spoonful over extended periods to help cure soldiers with malaria. For these reasons I regard MB as being quite safe to use over long periods of time.

But if you are concerned about continual use of MB, you could perhaps just use MB for 5 days a week with two days off. Or you could just take a week off after using it every month.

It's also important to ask why you are taking MB. I take MB for preventative reasons -- to aid my immune system against any unwanted, invading viruses and I also take it to help supply more oxygen to my brain to help protect my cognitive abilities.

For myself, I tend to just alternate using low dose MB with using BHT or Butylated Hydroxytoluene which also kills viruses and which is a useful anti-oxidant that acts to quench damaging free radical activity in the brain.

I'm currently considering using an MB + DMSO mix transdermally. Such a mixture could perhaps be used as an ant-viral, anti-fungal, anti-bacterial, anti-oxidant for anti-aging and as an anti-cancer treatment as well. More on that later.


Great ideas Bill. I wonder if DMSO and MB topically would remove moles from the skin. Please do post again any results from topical application.


Just came across your post as I am about to start using MB for general health reasons. You mentioned moles to remove on skin I have heard that castor oil on its own or some people mix cayenne pepper with it could do the job on moles. Perhaps worth looking into out if you haven't done so already?

Anxiety, Panic Attacks, Intestinal Cysts

UPDATE; Four months of Methylene Blue.

It has no effect on chronic fatigue - doesn't give me any energy; also doesn't keep me up at night if I take it right before bed.

There are two areas where it seems to have worked magic: Cysts and Anxiety; as well as other benefits for insomnia and problem solving.

It did clear up my long term liver/kidney/diaphram/intestinal cysts, and for that, I am very grateful. I stopped taking it for about a week, and the pain radiating from what used to be the most painful cyst began to return, so I am sure this is what fixed them, although I have no idea why it came back and whether to continue taking MB indefinitely.

Anxiety: There's something about MB that fixes my generalized anxiety. It's fairly miraculous in that regard. I did not take it for anxiety, but I notice an improvement (almost total resolution) when I take it. As a result, don't need xanax. Again not sure whether it is safe to take indefinitely for anxiety.

Along with the reduced anxiety, it helps me to focus more on problem solving. Not a complete resolution but a definite improvement. I have chronic fatigue related brain fog, and it definitely gives a boost in that department so I can see why it is being used successfully in Alzheimer's patients.

I think I am sleeping better -- deeper sleep, not getting up so much in the middle of the night, because of the MB, which is huge because I've lived through 25 years of insomnia. Used to take RX sleeping pills of various kinds (4-5 days per week) but not taking them anymore.

When I first started the MB in Feb 2013, I experienced significant tingling in my head (felt like brain buzzing). I was taking several milligrams of melatonin per night, and drinking coffee during the day. Both of those were a problem while taking MB but now, after a few months, I am able to drink a regular cup of coffee now and then with no adverse reactions. I also take a much lower dose (1. 5 mg) melatonin with no side effects. For some reason, tea creates no problems.

MB had no effect on yeast/candida, herpes related virus, or fungal infections.

Other than occassional "brain buzzing", I think MB may have a negative effect on vision (blurrier, esp at higher doses). It MAY have a positive effect on acne but I've been taking a skin/nail/hair formula as well and think it is because of that that my acne has improved.

I am taking 3-5 drops of 0.1% per day.

Perhaps E.C cross post this to Anxiety/panic attacks; and intestinal cysts.

I had tried methylene blue for my brain fog, lack of energy and achy joints, etc. I've been told I have Fibromyalga or Chronic fatigue. I didn't get any great results.

After further study I feel I have Lyme's and overgrowth of those little critters: Borealis bacteria. I urge you to read (google) all you can about Dr. Lee Cowden's protocol. He is doing medical studies using certain herbs and detoxifiers to kill off these bacterial invaders. This is probably the root cause of your problems. This info has changed my life, hope this helps anyone suffering from strange symptoms the medical doctors can't figure out.

5 drops? ...I am taking 40 drops of Methylene Blue and do not see much of an improvement, but I am taking it only for 3 weeks so far.


I just read somewhere that too much of MB has the opposite effect. I have also cut and pasted from a nootropics page what happens with co q 10 ...

"Methylene Blue donates electrons in the electron transport chain in your mitochondria. So experienced neurohackers suggest avoiding CoQ-10 or idebenone when using MB because it seems to make Methylene Blue much less effective."

I also thought I had Lyme disease. It turned out that I had an ongoing toxic mold exposure, that nearly killed me before I found out what it was (and not from a doctor) and got out of my house that had a hidden water leak. Lyme and CIRS (toxic mold illness) have extremely similar symptoms, and common mis-diagnoses are CFS, Fibromyalgia, and any other "syndrome" disease.

Anyone whose doctor says "it must be a virus" yet it never goes away, should go read survivingmold site. Water damaged buildings are common but the vast majority of physicians are not cognizant that 24% of the population has a genetic haplotype that is susceptible to the toxins. So only 1/4 of the people in a water damaged building will be extremely ill, and the other 3/4 either not ill or only with niggling minor illnesses. Well worth a look for the CFS/Fibro people. If I hadn't found out it was mold, I'd be dead.

METHYLENE BLUE, I have been using MB topically on benign skin lesions, the doctor had been freezing them off, but they eventually come back and the freezing is painful. So I just applied the 2.3% (fish stuff) directly on the spots. They take up the dye, and dry up, I reapplied it to the larger spots a few times, the small spots just healed up very fast. skin is looking great, no pain.

My dad was diagnosed with mantle cell lymphoma back in Feb 2007. He has been thru chemo several times and it's to the point now that he just can't stand the strong treatments and they aren't effective now anyway. We have always believed that God put natural methods here to cure cancer etc. And one of his friends told us about Mary Martin Sloop who back in the early to mid 1900's took methylene blue for cancer after the Dr. had cut her open and then sewed her back up because they said they couldn't do anything for her. Mary Martin Sloop went on to live 40 more years after taking the methylene blue. We have no idea how to get it, use it and would it even work for my dad now since he is in pretty bad shape. He is unable to eat basically as he has trouble keeping food down and is really weak. The Dr. gave him no more than a few weeks to live. Can you please let us know quickly if there is anything that would get him well. We don't want to prolong his suffering but we would love to get him back to his active lifestyle of bowling, biking and living for the Lord. Thanks and God bless, Kevin

Dear Kevin, I am so sorry about this situation, my heart go out to you family. You can search this site on lymphoma, cancer, methylene blue etc.. And try to find the what and how by yourself but your time is more precious. Your best chance is to contact Ted directly. He is using methylene blue in his remedies plus a few other components to help with cancer he is extraordinarly knowledgeable and generous with his knowledge and patience. He can give you a protocol to follow right away and that will save you a lot of time. Any way you can get methylene blue in an aquarium shop. That is where I got it and diluted it by Ted specifications. May your faith and the force of the univers guide you to good result!

Dear Kevin:

Methylene blue does effect cancer growth by turning the cancer tumors into aerobic, which stops their growth that way as cancer in general are aerobic. Methylene blue is acquired from stores that sell aquarium fishes. They usually have methylene blue 1%, whereby we reduce them by adding 1 parts methylene blue with 9 parts water, should get a relatively safe concentration. Then we can add methylene blue drops such as 8 drops and slowly add more so if there is no side effects. In Vietnam war they actually used far more methylene blue to treat malaria, such as methylene powder in milligram to gram doses. The methylene blue is synergistic with large dose vitamin C. What I do know for stage IV cancer, which is cachexia cancer, is B50 vitamin B complex, or B6 200 mg for example can reduce some of this cancer cachexia. The other is the use of Hydrochloric acid concentrated, at 8 drops per 250 cc of water and to that I will add between 4 to 8 drops of methylene blue and take this for an entire day until the cancer cachexia goes away. Another observation to restore the appetite and stopped cancer cachexia that I have found is B5 panthenol, or a possible replacement, pantothenic acid to be helpful. What I do not like about pantothenic acid is the calcium form since the get cancer worse. If it was possible for the methylene blue 0.1% is injected a 1 cc, into the tumor cells that could have done it's job also in staving off tumor, but that's just a theory, by interfering with cancer fermentation. In any case, there are other ways to resolving cancer cachexia such as megestrol which is progesterone hormone, if taken at fairly large dose such as 250 mg for example, or applied to the skin as safer means might actually stop the cachexia by neutralizing what they call TNF, which is a cachectin hormone that causes your inability to eat. The liver's inability to function from lactic acid is another problem that can lead to the condition also. A methylene blue is obtainable from a local chemist, a chemical company , a local aquarium shop, or a scientific supply store, or perhaps a school supply store where they do the slides to stain the samples using a 1% methylene blue solution.

Dear Ted,

I'm very unsure of what to do right now. My dad probably has a week or so at best to live and he is not eating, drinking very little and sleeps most of the time. I want to help him get well but I don't want to try something and prolong his suffering if we can't get him completely recovered. If it was your loved one and he/she was in this shape what would you do with the knowledge you have?

If doing something what exactly would you do?

I would basically reduce his suffering by restoring energy and nausea. As mentioned I used clove oil and methylene blue. To restore appetite I used b50 and HCl and at least the case I was involved with simply did not want to die. While that case was given a few days to live she is doing fine after 3 years. Yet in another case just last week in similar circumstances she simply don`t want to live so nothing was done because she refused any treatment even though the natural treatment for cancer was a success and hence nothing was done so she died in few days just last week. It was the patient that really have their say and if not conscious it just depend on the family's decision.

Replied by Tommy

Hi Josecito, Ted spoke about how to dilute 1% MB into 0. 1% MB. One part of MB in 9 parts of water will dilute 1% MB and make it 0. 1%. So if you want to make 1L of MB 0. 1%, you have to take 100 ml of MB 1% ( one part ) and pour it into 900 ml ( 9 part) distilled water. Another example, if you want to make 500 ml MB 0, 1%, you take 50ml MB 0. 1% and pour into 450 ml of distilled water. There is a lot of ways how to make the volume you want, you have just to follow the right dilution ( 1:9). I hope that can help you.

I was taking Methylene Blue (12-13 drops in 8 ounces of water) with a thousand milligrams of vitamin C for about a week & I noticed the severity of my candida related itchy skin was reduced, I then upped my dosage by a few more drops per day (14-15 drops) in about 9-10 ounces of water, and a few hours later my stool was loaded with dead candida overgrowth! I normally have bad constipation but this time my "relief" was smooth and easy I was amazed. Also, I use the Methylene blue stain directly on my skin where I have itchy candida rashes, yes it stains! But only for a few days & most of it will wash off with soap and water, so use it where it cannot be seen, and it will take you itchy rash away with relief within 10-15 minutes and the relief will last for like a week, until the bugs send out a new invading force! I have also use Methylene Blue in more diluted parts for itchy skin in more visible areas with relief & I found it is also good for tooth aches.

P.S when I take it in strong doses your urine turns blue for about a day, but when you stop taking it it turns back to normal & I take vit C 500-1000 mill and have had no problems with my eye coloring, which I also heard is reversible if you should happen to have that happen to you.

Research indicates Vitamin C may inhibit Methylene Blue's killing of Candida

Ted's advice on many areas of health have been of great assistance to me. I became interested in trying Methylene Blue for attacking my systemic Candida, and did some additional research. I came across a study that indicates that taking Vitamin C with MB may decrease the effectiveness of its impact on Candida. The research is found at

The relevant quote is halfway through the abstract: "... sensitivity of Candida cells to MB could be rescued upon the supplementation of ascorbic acid, an antioxidant." In the context of the abstract, this "rescue" seemed to be contrary to the intent of killing Candida cells.

Therefore, I began to take MB 1 drop twice a day (along with BHT), but taking ascorbic acid at least two hours later. My reasoning was taking such a small dose had no risk of side effects (coloring eye, etc.), but that any potential impact on Candida would not be lessened by the ascorbic acid.

I understand that Ted is not currently up to responding, but am hopeful that this information may help others, if you or someone may take a look at it and comment on how to take MB and Vitamin C (perhaps 2 hours between the two?).

Hoping this may assist others in recovery from Candidiasis;

Sincerely, Susanna

Note the study was by NCBI. I thought a world renowned doctor for research and use of MB stated that vitamin C BUFFERED ENHANCES MB effects. Forgive me if I'm wrong, and congratulations if it's working for you as a safer and less invasive means to help your conditions.


I take MB with ascorbic acid (vit. c), 1% or 2.33% MB and a approx 1/8 tsp vit c powder in h2o. my MB dose is not always the same, as it depends on which dilution I use. if using 1%, then I take approx 20 drops 2x/day (so, 40 drops/day) from the supplied dropper to = 10mg 2x/day (20mg/day) for tinnitus, which it has helped. As an aside, my memory has improved. I was actually taking more MB but it gave me really loose stool so I backed off to this dose, which is fine. We'll see how it goes. I also take a day off from MB every so often.

Hi Lynn,

I just finished reading an article by Dr Mercola who interviewed a Methylene Blue (MB) researcher. The researcher said there used to be pills of 60 mg MB that were used for UTIs. He put his mother on a dose of 1mg per kg body weight a day. He generally recommends 0.5mg/kg up to 1mg/kg (pharmaceutical grade as any others have heavy metal contamination) taken with 1000 mg of Vit C in the ascorbic acid form as it reduces the MB to be bioactive.

I just started taking 3drops in about 6oz of water per day, working up to a dose that I can feel better with. My rough calculation is that with 10mg/ml of MB, my weight of 118 in pounds becomes 53.5kg, divided by 2 for the .5mg/kg (or you can multiply by .5, your choice, same answer) becomes a good dose of 26.75mg MB which is then 2.675ml, which then is slightly over 1/2 teaspoon (conversion charts are amazing). It will take a lot of drops to get to that dose! But if a lower dose works, I'm happy.

Chronic Bladder Infections
Posted by MHO (Provo, UT) on 03/18/2022

I am an intermittent catheter user, therefore, I have chronic bladder infections. Ever since I began using Methylene Blue I have stopped getting UTIs. I use Methylene Blue 1% solution. The normal dose is 10 drops in water morning and night. I only need 2 drops morning and night. I use a straw to drink it so my teeth won't turn blue. It has the added benefit of stopping my candida symptoms.

Having said this, I am also very careful about what I eat: no sugar or fruit of any kind. I don't use any artificial sweeteners. I avoid wheat and other grains. I eat canned beans, eggs, fish, chicken, vegetables, and brown rice. I have to avoid nuts.

Hi Lynn,

My neighbor and some of her relatives had trouble with recurring UTIs, and she found a probiotic that is sold on Amazon to stop this in everyone who has tried it. We also had a friend who had the same problem and was very ill, so we gave her several packages that my neighbor had on hand, and she is now completely well, as long as she takes the probiotics. She thinks it is worth the cost to stop getting the UTIs. It might be worth a try.

Best wishes!


I know that probiotic and it also contains a very powerful cranberry concentrate along with the probiotics. It sure does get good reviews.


Would that be D-mannose? That stuff works wonders for UTI's.


Yes, it is great... BUT... if you do get a UTI in spite of using D-Mannose... I used chlorine dioxide solution (CDS) to cure a nasty UTI in just 2-3 days... nothing else.

I've been reading about recurring infections as I've been looking for a reference I lost track of...apparently, infection can "hide" in areas of heavy metal deposits and regenerate from there. Apparently, heavy metals tend to accumulate in areas that are already compromised, providing unfriendly microbes with shelter from the immune system.

In cases of chronic dehydration - which it is thought that most people are chronically dehydrated to some degree - the body is in a sustained "emergency mode" of water rationing during which some systems are slowly and steadily sacrificed to dehydration to assist the body in getting as much hydration to critical systems as possible.

This would explain why a rehydration scheme has such favorable effects on such a huge variety of different issues and systems. And I reckon a system that is slowly being sacrificed would be a safe place for heavy metals to accumulate. Otherwise, they'd simply be identified and flushed out as "foreign material".

I found that methylene blue works great for chronic fatigue. It was like someone hit my on switch. My energy level and thinking improved drastically and I was easily able to give up caffeine. However, the reason why methylene blue was able to work so well for me is that my chronic fatigue was due the fact that methylene blue treats mitochondria damage, and I have mitochondria damage from taking Cipro. Never take Cipro.

I found out the hard way. Methylene blue is sometimes deliberately contaminated with arsenic, possibly to prevent us from benefiting from a safe effective product. The type I bought had a warning label not to be used in food producing fish. I called the store I bought it from, they said it did not have arsenic. This was a lie.

I suffered greatly from severe arsenic poisoning. I wish there was a way to be sure the source was pure, because aside from the arsenic, methylene blue was great stuff.

After reading your website, I was excited to try out the methylene blue for my yeast and "brain fog". I followed instructions, taking it with powder vit c and baking soda. I took it only one time because in researching a bit more, I saw where taking Methylene blue with anti depressants can cause serious problems with the serotonin in the brain.

"Although the exact mechanism of this drug interaction is unknown, methylene blue inhibits the action of monoamine oxidase A—an enzyme responsible for breaking down serotonin in the brain. It is believed that when methylene blue is given to patients taking serotonergic psychiatric medications, high levels of serotonin can build up in the brain, causing toxicity. This is referred to as Serotonin Syndrome. " (food and drug administration webpage)

I have been on effexor for 10 years, and although I plan to go off this slowly in the summer, it looks like I will not be able to use the methylene blue as planned.

Was this on your website and I missed it? If not, you might want to add this information. I'm glad I caught it, but very disappointed I cannot benefit from taking the methylene blue. Any other suggestions?

The only drug known to inhibit the excessive production of reactive species and cytokines is methylene blue, a low-cost dye with antiseptic properties used effectively to treat malaria, urinary tract infections, septic shock, and methaemoglobinaemia.The relatively poor efficacy of anti-cytokine drugs is explained by the fact that they act on one or a few of the dozens of cytokines involved, and because other mediators of inflammation – reactive oxygen and nitrogen species – are not targeted. When produced in excess, reactive species cause extensive cell and tissue damage.

Using Methylene Blue is not just a hypothesis.Regarding using methylene blue(MB) against COVID-19 ARDS, there is an Indian doctor, Dr Deepak Golwalkar, who, as a pulmonologist and lung specialist, has been using his nebulized/sublingual MB treatment for quite a while and with great success for his pneumonia patients and for his COVID-19 patients with ARDS. Here is his website, which details his treatment:

Interestingly, Dr Golwalkar also uses exactly the same concentration of MB for nebulizing -- 0.1% methylene blue -- which is the same concentration that Ted from Bangkok recommends.

DMSO Represses Inflammatory Cytokine Production from Human Blood Cells and Reduces Autoimmune Arthritis


Dimethyl sulfoxide (DMSO) is currently used as an alternative treatment for various inflammatory conditions as well as for cancer. Despite its widespread use, there is a paucity of data regarding its safety and efficacy as well as its mechanism of action in human cells. Herein, we demonstrate that DMSO has ex-vivo anti-inflammatory activity using Escherichia coli- (E. coli) and herpes simplex virus-1 (HSV-1)-stimulated whole human blood. Specifically, we found that between 0.5%-2%, DMSO significantly suppressed the expression of many pro-inflammatory cytokines/chemokines and prostaglandin E2 (PGE2). However, a significant reduction in monocyte viability was also observed at 2% DMSO, suggesting a narrow window of efficacy. Anti-inflammatory concentrations of DMSO suppressed E. coli-induced ERK1/2, p38, JNK and Akt phosphorylation, suggesting DMSO acts on these signaling pathways to suppress inflammatory cytokine/chemokine production. Although DMSO induces the differentiation of B16/F10 melanoma cells in vitro, topical administration of DMSO to mice subcutaneously implanted with B16 melanoma cells was ineffective at reducing tumor growth, DMSO was also found to block mouse macrophages from polarizing to either an M1- or an M2-phenotype, which may contribute to its inability to slow tumor growth. Topical administration of DMSO, however, significantly mitigated K/BxN serum-induced arthritis in mice, and this was associated with reduced levels of pro-inflammatory cytokines in the joints and white blood cell levels in the blood. Thus, while we cannot confirm the efficacy of DMSO as an anti-cancer agent, the use of DMSO in arthritis warrants further investigation to ascertain its therapeutic potential.

Hi Lisa, Hope you won't mind my seeking your advice. I bought 20gms MB Powder and have a set of scales (manual) that weigh in 50mgs So was able to get to 1mg which I put in 1 litre brown bottle and topped up with water. Dr Deepak Golwalker told me this so now I have a 1% solution. How many drops to take or start with? I weigh 70kgs and am 82yrs old with Isolated Systolic BP and Bowel cancer which I manage myself having refused surgery. If you could advise would be extremely grateful.


a 1% solution is 1 gram in 100 mls of water, or 10gm per liter.


This is Pam, my sincere apologies for getting this wrong. 1gm MB in 1 litre water which Dr Deepak told me could even be tap water (preferably filtered) as MB will deal with anything in it. This will give you .01%, think that is correct now. Whatever this was what Dr Deepak wrote to me when he so kindly answered my letter asking for help. I measure 1gm into water and add to a 1 litre brown glass bottle. I bought some small wide neck 5 gm bottle to put 1gm powder in for this purpose makes things easier but do cover worktop well its amazing for infiltrating everywhere it shouldn't! I take 10 drops in the morning and 11 drops late afternoon, excellent stuff.

My daughter got rid of all her painful, aching bones (Lyme) disease using this 10 drops 2x daily and swears by it. now. I use her method of putting the drops into a shot glass and have a mugful of water with 1gm Vit C some before and rest straight after taking the shot.

Hello Pam, have you read the book "miracle in the hills"? Dr. Mary Sloop. A woman had cancer in her intestines and the doctor operated and closed her up saying it was inoperable, so the country doctor gave her MB and she lived at least 40 years. It is on page 43 chapter 9.

Great job, Pam!! Are you new to MB? I guess the Rife machine is responsible for most of your success?

You might look into chlorine dioxide solution (CDS) as another tool in the toolbox... Dr. Kalcker is the expert... here is a good start:

(Colorado USA)

MB has been thoroughly studied and tested for 150 years. MMS/chorine dioxide has NOT been tested in any credible way, in fact it has been banned from many countries with explicit warnings against its use. It is a very strong oxidizer like chlorine is, even though it is partially neutralized by the citric acid. It is not tested scientifically on humans nor animals; I defy anyone to find credible studies. Dr K is the main pusher of this toxin, funny how not even one researcher in a million gives MMS any credibility. It is not proven safe whatsoever. Unless and until someone actually runs a credible trial of at least hundreds if not thousands of people, MMS is a dangerous gamble. I tried it as I have H2O2-08 and it made me sick as hell. Please inform us how it discriminates killing only the "baddies"? Ive now read of many people harmed, possibly even some deaths. It does not have "humble" origins. It is also heavily conflated with specific religious beliefs, never a good sign when you conflate science and facts with religion; caveat emptor...


That's not true. Credible studies have been done in Russia with positive results. It has been used to clean water in other countries for decades. I was born in Spain and my mother said they used it to clean the water there 60 yrs. ago. I'm sorry but there are thousands, if not more, testimonies of people who have used MMS with great success. I don't wish to debate with you, just saying you should do more research.


NO ONE is making any of those claims there. You sound like a shill against it. WATCH THE RED CROSS DOCUMENTARY they did on CDS. Why don't you post that on the Dr K CHANNEL THEN and ask her for that instead of ranting nonsense here? HAH

Pam, to make a 1% liquid Methylene Blue, add (1 gram) MB powder to 100 mL of distilled water. Most measuring cups have a 100 ML line for reference for the water. To mix it together, I use an empty, clear plastic soda bottle with a screw-on cap. Pour in the water first, then pour in the MB powder. Shake it 200 to 300 times to ensure the powder is all broken apart and mixed well. Then, carefully fill your 50 mL empty MB eye-dropper bottles you've saved when you bought the liquid form. If the liquid level is hard to see while pouring MB in, shine a flashlight beam through the bottle towards your eyes, so you can see the level in the dark bottle. Go slowly for best results. Good Luck.


Hallo Kr8peace,

MMs ist schon lange überholt. Chlordioxid ist neue formel. ein lesen. Ein glas wasser ist gut zehn glas wasser kann dich Töten... Paracelsius hat gesagt dosis mach das gift... Ich nehme selber 10 jahren Chlordioxid und besten gesundheit. Informiere richtig nicht ein seitig bitte...

Hello Kr8peace,

MMs is long outdated. Chlorine dioxide is new formula. Read A glass of water is good, ten glasses of water can kill you... Paracelsius said dose make the poison... I've been taking chlorine dioxide myself for 10 years and I'm in the best of health. Inform properly not one-sided please...

Wow, that's awesome. Have you heard of it helping to heal the Gut, or anyone who's tried it to rid the body Heavy Metals? (Or might it also HAVE Heavy Metals in it?)😜

(I have a lot of issues…so just started taking it).

I am having a blonde moment with math. I got a high quality 30ml (1 oz) bottle of Methylene Blue with 300mg of MB in it. 1 drop was .5mg so I did that for 2 days with 1000 C. My eyes did turn a bit blue. Most of the calculations are for 2.3% and Ted's 1 gram powder to 1000cc.

So Help Please. It would be so beneficial to know how many mg or mcg makes up 1%, and/or .1%. AND how to get 30ml of 300mg to 1% since it's not a powder.

What's crazy is seeing doses of 15mg (which would make my eyes navy blue ; ) online.

Any help is greatly appreciated.

If you supplement a good quality vit.c with M blue, the whites will not turn blue.

300 mgs, or 0.3 grams in 30 mls is 1%. A 1% solution is 1.0 grams in 100 mls liquid.

With a 1% solution of methylene blue 1 drop = 0.5 mg. In Sloane's book available on Amazon 6mg. or 12 drops of the 1% solution should produce noticeable benefits for a 150lb. person.

The concentration in the flask u bought is 1%.
300 mg = .3 gm
It is also assumed that 1 ml = 1gm
Your total volume is 30 ml
Therefore, .3 divided by 30 (times 100 to get the percentage value) = 1%
