Better But With Side Effects

Half way through completing 20 day master Cleanse lemonade fast I started taking daily dosage of 35% food grade Hydrogen Peroxide in carefully monitored drops increasing to limit of 25 & subsequently decreasing dosage down to 3 drops, 3 times a day. On day 20 I felt as good as I ever have in my life

1 week after I developed continual pins & needles in my hands & fingers & weakness & instability in my legs that has stopped me from running daily in the gym.

I am currently awaiting results from a complete clinical analysis to determine what is wrong.

has anyone experienced these or similar symptoms or can anyone offer a diagnosis?

After the 7th day of 35% h2o2 therapy I had to stop. I noticed shortly after beginning the therapy my stool were almost black. I was afraid it was causing some sort of bleeding. My stools prior to this therapy were normal. Hopefully I didn't damage myself with this experiment. I was up to 10 drop 3x per day in 7-8oz. distilled water. Never had bowel movements that dark before that I can recall.

I would be careful of using distilled water long term. It depletes minerals because it is an active absorber. I know there are a lot of myths out there about useage. But, there are facts. I wanted to find something that everyone would trust so I turned to a post by Ted in the distilled water remedies section dated 12/16/2008.

"1. Long term used of distilled water is not healthy
2. Distilled water only short term use may help detoxify, but never use more than for a couple of days.
3. Distilled water depletes the body of bicarbonates, causing metabolic acidosis in the long run.
4. Some people use medicine added to distilled water to help absorption. This doesn't work for me because you are going from a lower concentration of distilled water to a higher concentration blood. Hence, more concentration of blood would not help absorption."

I'm not sure I understand what peroxide can do to distilled water but, I am concerned that it could make it worse and acidic.

Perhaps someone with more knowledge can enlighten us... but, thought a word of caution should be raised regarding long term use... which the h2o2 therapy is for. I think Alain from Ottawa, Ontario in an answer to Lucy below was a good idea. She mentioned adding baking soda to the mix. Which sounds like a really good idea according to the information provided by Ted regarding bicarbonate absorption.

Comment to Rainman from Central, Vt about hydrogen peroxide and distilled water (internal use)

As per http://cancertutor.com/Cancer/HydrogenPeroxide.html

"I would not put the drops of hydrogen peroxide in anything but highly distilled water (grocery store distilled tap water is not acceptable, either get double distilled tap water or distilled natural water). The reason is that other chemicals in water may cause a chemical reaction that prematurely strips the extra oxygen atom from the hydrogen peroxide atoms."

As per the possibility of detrimental long term use of distilled water, I saw both sides of the arguments. Those recommending distilled water would say that the minerals on water (especially hard water) are not bio-available and will create with time mineral deposits and stones. I am not saying that I agree with this. At the moment I don't know enough.

My feeling is that for a person whose pH is balanced, this may not be a problem, and that a person whose is acidic will have its body try to use those "non bio-available" minerals and creates deposits and stones.

The black stool is toxins being expelled by your body. It means the H2O2 is working. When I first started psyllium husk, my stool got very dark. It gradually - over several months - lightened back up. This was the toxins in my digestive tract. (My cholesterol went from 227 to 186 in three months. ) Recently I started chlorella and my stools are very dark again. I am happy to see this because I know what it means.

I can't figure out this thing about using distilled water. Rainwater isn't distilled, neither is sea or river water, or ground water, yet they all contain trace elements of H202! I can understand not putting H202 in chlorinated water, but not in filtered spring or mineral water. Healing artesian springs contain both H202 and minerals.

I also don't understand why the H202 needs to be so radically increased. H202 in 'living' water is only in very minute amounts yet is beneficial. More is not necessarily better. Surely regular ingestion of minute amounts (1 - 3 drops 35% HP in 8oz water) is better in the long run than large unnatural quantities that cannot be tolerated very well. Healing spa water often contains in the region of 0. 25% concentration. If that is healing at that level wouldn't that be enough?

I was doing a 6% h202 therapy on myself by drinking the food grade type but i started getting ear and throat pains after drinking it for a few days and i even have a lump on my left side neck where my throat is.

Do you think i should keep on drinking it and put some eucalyptus oil in my ear and gargle with water and the oil while im going thru the therapy if i must keep on taking the H202?

Answer to Lucy from Sleepy Hollow about H2O2 side effect

Hi Lucy

You should tell us what you exactly did.

The maximum concentration for internal use is .5% as per Ted's
"In the alternative health field, the maximum is actually 0.5% concentration. Actually and optimum H2O2 concentration was first determined in 1950s by Dr. Reginald Holman by implanting Walker 256 adenocarcinoma tumours. The drinking water for the rat used H2O2 optimum concentration needed to kill the tumors were about 0.45 percent.

Tumors completely disappeared in 15 to 60 days in rats. Of course a better way is to add 1/4 teaspoon of baking soda in the glass of 0.45% concentration of H2O2. This can be extended to treatment of almost any kinds of conditions, from virus, bacteria, microbial infections, pneumonia, tuberculosis, flu, etc. My own experience of using just baking soda (also increases the body's oxygen) and ascorbate vitamin C about three weeks for a small tumor to go into remission.

A more effective I think in the future of peroxide therapy is to add baking soda to the 0.45% concentration to normal drinking water since baking soda is alkaline and increases oxygen, while the peroxide furthers this natural increase."

To reduce 6% to 0.5% take 1 volume of FG 6% H2O2 mixed with 11 volumes of distilled water. But since it is the maximum you should start with much lower concentration and increase gradually. You can start as low as 0.05% (and even lower). H2O2 is powerful stuff. It is better to be on the safe side.

-Use Food Grade H2O2.
-Drink the diluted solution on empty stomach.

Good Luck

I have a question for anyone who might know.

I am on the H202 oral treatment and following according to Ted's recommendations and now have the detox symptom of a bad head cold. I know that this is detox because I don't get colds!! I haven't for many many years. But now my children have this same head cold; and are NOT on the treatment, so I'm wondering if a detox symptom like a cold can be contagious. I understand that h202 can kill parasites in the body and I've learned from Hulda Clark that inside a parasite lives many viruses including cold viruses, and that when a parasite dies it releases them into the person-host. So this detox of a head-cold might be contagious then right?

Has anyone read anything like this or had a similar thing happen? I then gave the kids all 5 drops of h202 hoping it would stop this cold - but it hasn't done anything. Any ideas?

I have been ingesting the 35% food grade hydrogen peroxide, diluted to a 3% solution...I am currently taking 1oz in 5ozs of water, 3xs daily, for a week and then I increase...however during the course of this protocol I have noticed that it is exacerbating my immune system conditions...also, when checking my urine ph levels, I was already acidic, but it seems to have made it worse for me. I am at a 5.5 when taking it...can anyone suggest why this is the case and what I can do to make myself more alkaline? Would a combination of baking soda, or apple cider vinegar do the trick?

I tried the popular internet dosing routine for the diluted 35% food grade Hydrogen Peroxide protocol, about ten days ago. The protocol that I attempted was as follows:

Day 1: 3 drops, 3xs a day
Day 2: 4 drops, 3xs a day
Day 3: 5 drops, 3xs a day
Day 4: 6 drops, 3xs a day
Day 5: 7 drops, 3xs a day
Day 6: 8 drops, 3xs a day
Day 7: 9 drops, 3xs a day
Day 8: 10 drops, 3xs a day
Day 9: 12 drops, 3xs a day
Day 10: 14 drops, 3xs a day
etc.etc. up to 25 drops, 3xs a day.

I was only able to complete this protocol for at least ten days.

When I first began I diluted the 35% food grade Hydrogen Peroxide drops in about 6-8ozs of water. It immediately began killing my stomach and so I increased my water to about 9-11 ozs...11 ozs is way too much water for me to ingest at one time...it made my stomach feel as if it were going to blow up...then someone suggested that I dilute the 35% food grade Hydrogen Peroxide in 8ozs of milk which I tried, to no avail...In the past I have suffered from stomach ulcers and this regimen most certainly exacerbated my condition, or perhaps created a new one...it felt like it was ripping my stomach in half...now, perhaps this solution must be further diluted, I am not sure, but what I am sure of is that the initial protocol, that is widely distributed via the internet, was without a doubt a tremendously painful experience for me. I am not in any way indicating that it will most certainly be someone else's experience, verbatim, but nonetheless I feel the need to share what has happened to me in order to possibly aide someone else in their attempts. I do not think that the former protocol for diluted 35% food grade Hydrogen Peroxide is good for ulcerous stomachs...you must be extremely careful if you have these issues...that is really all I can say...

If you have an ulcer you should deal with that first. 2 ounces of fresh cabbage juice 5 times a day for a couple of weeks will usually do the trick. Most ulcers are caused by NSAIDS (aspirin, Tylenol, Advil, etc.)so you need to watch those. If this doesn't improve things you'll need to have your doctor run a few tests to see if something larger is going on.

Your stomach might have felt that way due to the way you ate. You are NOT supposed to take the dose one hour before or after eating due to the acid in your stomach dissolving and the oxygen going through your body. This is true. Because I have a book that explains everything. You can try again with the schedule of no eating and hopefully you will have different results.

And here are my thoughts on the 3% store bought hydrogen peroxide:

First of all I have seen all of the postings, via the internet, about using the 3% store bought hydrogen peroxide as mouth wash, etc. so I tried it...on the back of the bottle it says to mix it with an equal amount of water...well, first off I tried it mixed with an equal amount of water and I also tried a miniscule amount of it straight...as mouthwash...I gurgled it around in my mouth, morning and night, after brushing...it made my gums extra sensitive and made them crack open and bleed, all over...the one thing that it did do was kill the toothache that I had...so, perhaps I did not dilute it enough, or properly, etc. and again, I state that this is only my personal experience, and as such, it may not be applicable to everyone else, but it is important to note, nonetheless...

In 2007 I went on the h202 therapy and so did some of my friends. They had reactions like diahrea, stomach cramps and such but plowed through it.

I didn't have any reaction but I started out with 1 drop per day in 6-8 oz of water but also added Colloidol (spell?) silver-they work great together. I worked my way up to 11 or 17 drops per day with no reactions.

It may be that sometimes the detoxing in the body that goes on can be somewhat painful or a discompfort and I have read that the stomach may blow out a bit-theres a lot of stuff in the body that is dead and the H202 is eating it up, but not harming the healthy tissues.

Anyway, it was a great experience for me because it lowered my hepatitic C viral load from 23,000,000 copies down to 5,000,000 copies. I stopped because you ARE supposed to NOT EAT 3 hours before and for 1 hour after, maybe that is why I didn't have problem with it.

I love coffee first thing so I made sure I woke up during the night/am-3-4am to drink the H202 (kept the container I was using in a bucket of ice water to keep it cool during the night)and went back to sleep. This way I wasn't going throughout the day with out eating for such long periods of time.That is why I stopped, but I am starting back slowly now to kill the rest of the virus. I am starting with 3% in a gallon of water so that I don't have to fast yet and will work my way back to the normal protocol of NOT EATING 3 hours before and 1 hour after-I like to eat! 8-)

I am new to this site and haven't spotted where questions should be submitted, sorry. Can I please ask this question here and you put it where it belongs? I hope you agree it's important. Here it is:-

"physicians like Dr. Farr believed that taking hydrogen peroxide orally could have a corrosive and tumorous effect on the stomach and small intestine and advised against using it. There is animal research supporting this caution".

He advocated intravenous treatment.

Does anyone know what these animal studies were, and what amounts of H2O2 were involved? Should we be worried about this?

Please help!!!! I have fibromyalgia, emphysema, dry eyes, and a heart that doesnt rest right. I stared taking 35% hydrogen peroxide over 2 weeks ago and at first was amazed at how good I felt just taking 3 drops a day. After slowing starting to increase the drops each day I am getting alot of side effects. These effects being pain and numbness in my chest and my eyes hurt more with blur vision. I am now up to 9 drops 1 time a day and need to know if I should continue or quit and are the side effects I am having a sign that I am getting better or that something is wrong and I should quit? Thanks for any help and thank you.

when u started with the 3 drops, u probably shouldn't have increased it to 9 drops, that was probably too much if u r feeling sideeffects, u should probably discontinue it until you r feeling better, u do not want it to get too far out of hand, then u will have more problems than u can handle, good luck

Hydrogen peroxide has a lot of great uses, but I would be careful taking internally. I bought it as an O2 vitamin but I didn't notice any benefits. Try applying to a stain because it is really good at cleaning. Apply to a cut and see how it sizzles. I would be careful with the dosage. 9 drops sounds like too much.

One teaspoon of hydrogen peroxide? Of course you took too much. No wonder. Where on earth did you get that dosage? I truly hope you were not taking 35% food grade. Stop drinking peroxide! You are only supposed to start with a few drops. Drink a gallon of distilled water a day to flush out your kidneys.

Replied by Sophie

The quantity you took is too high if you took 35% hydrogenperoxide. But with regards to your symptoms: symptoms are good. They mean that the hydrogenperoxide found an area that it deemed it needed correction.

I have had, since I started, February 3rd... 43 days ago, I have had several 2-3 day periods when I didn't feel well, then I had extremely smelly urine and/or fecal matters for a day or two, and thereafter I had a 2-3 week long clarity, increased mobility, reduced cravings, etc.

So I say, pray for "side effects" because they are not. If you are like me, storing lots of poisons from lifestyle, you want it to be digested by the hydrogen peroxide and empty it through the elimination channels.

One serious warning: if you don't want to re-absorb the poisons, make sure you have a serious colon cleansing to start with. Enemas, colonics, or any of the commercially available colonic cleansing supplements are good. Just do it.

I didn't do it, and I think, at least partially, that is why I had so many healing crisis in the 45 days.

Please let us know how you are doing? OK?

H202 not to be messed with:

I have taken 35% food grade h202 several times through the last 7 years of my life. always starting at 1 drop and increasing 1 drop a day as far as 25 drops and coming down in the same manner sometimes staying at a certain dosage for a few days.

One day i felt i was getting sick. I hadnt taken h202 in over a year. i decided to experiment with it. i took 10 drops one day skipped a few days and did it again. this is not reccomended as it caused my body severe problems. The h202 shocked my system into a clensing crisis through the skin via Herpes Zoster better known as Shingles.

it was very painful and the nerve which was affected followed into my eye and caused me to get iritis. the iritis caused my vision to go blurry in that eye. I was able to get steriod drops from the opthamologist and managed to rid myself of it after a few months.

I am a firm believer in h202 and its healing abilities but heed my warning: H202 is not to be taken for granted.

Dear Friends: DO NOT use hydrogen peroxide in enemas or colonics. i tried it once and ended up in the hospital. when the HP hits the bacteria in the colon it explodes and causes severe painful cramping and uncontrollable contractions. i was sick for almost a week and put on a iv for dehydration. ive talked to other people who have done this and ended up in the emergency room too. i am a believer in hydrogen peroxide cures. i inhale it and have not had a cold or coldsore of been sick in 3 years. honest!! inhaling is the best method in my experience. i even swallow whats left in my mouth and never have a problem but never never never use it in an enema!!! it could kill you. it could cause intestine to burst and bleed to death. a painful horrible death.

Just to let people know that I got a condition known as hairy tongue about a year ago when I first started messing about with H202. If you are going to use it for a mouth wash, make sure that even the 3% Peroxide is diluted. At most, the ratio is supposed to be 1:5 in the water.

Anyway, I took it straight and it caused a horrible unsightly condition called hairy tongue which I have NOT been able to get rid of. I have posted something on this site about six months ago - tried everything, salt water, h202 dilute, lemon water, brushing it with a scraper etc and NOTHING works.

I am not knowing Hydrogen Peroxide. I am sure it is good stuff and has its uses but don't use it as a mouthwash like I did without diluting it. Be careful when experimenting.

Take Care (and if anyone knows something that can help me, please let me know)

re hairy tongue from hydrogen peroxide: I heard that you can restore the body's natural defense (an enzyme???) contained in our saliva. So find someone to kiss, and soon it will be naturally consumed. :)

in response to the hydrogen peroxide swisher that ended up with 'hairy tongue'- I spoke to a chinese medicine/natural doctor about this, as the clinic recommends swishing with it once a week in oral hygiene care. She told me that hairy tongue is a fungal reaction, and that the reason this would have happened is one would have to have a lot of fungus and bacteria in the mouth. In an act of detoxification, as the fungus and bacteria is pulled out from swishing, this COULD happen (not common, though.) Their recommendation was to keep swishing once a week to continue the detox process.

Hi Beth, Those huge 4 zits could just be coincicence or it could be that your peroxide is making some bad guys exit through the closest route - your skin.

I have read that toothpaste will dry up those zits but I personally would probably use peroxide externally on them because it doesn't contain all that toxin called fluoride that brings us other unwanted problems, and it does kill off bad guys.

If your problem is history, why continue the treatment? You can find a good liver cleanse at any health food store and you will likely find that they are loaded with two weeds everyone is trying to eradicate from their yards: thistle and dandelions! Both are known to be liver friendly.

You may have experienced the skin eruptions because of the toxins leaving your body quickly-- certain parts of the face correspond to organs too- I remember reading once that the chin reacts from the liver- ..boils tend to hurt reeeally bad...and go deep into the tissue--I think you'd know ...hydrogen peroxide on them will help clear them out. I think I would tough it out and don't stop too early out of fear...that's usually why people don't get results they are seeking. Best luck to you!
