I cannot get past 5 drops per day twice a day any more and I feel violently ill. How long can I keep taking h2o2 this way and will 5 drops twice a day kill the mold in my lungs?

I purchased FGHP and immediately began using it with the incorrect dosage. Like an idiot, I mistook a drop to mean one whole dropper. You can see where this is going. I did three whole droppers the first day and the physiological effects were perceptible that evening. My throat felt scratchy beneath the Adam's apple and I suffered from nausea. I repeated the incorrect dosage for a few more days until it was pointed out to me that a whole dropper is not a drop. A Eureka moment ensued. I ramped down to 3 drops, not droppers, and although the candida in my stomach was decimated (which was partly my initial intent taking FGHP) I experienced a general discomfort and have since ceased taking the product, figuring I would give the body some time to recover.

Now, almost a month later, my body quivers and anxiety has stricken my mind. There are times when my brain lapses momentarily. I suspect this is a result of the overdose and could use some clarification or confirmation and certainly some guidance. It was my mistake and no one's fault but my own (I was never good with details). Granted, there were extenuating circumstances which I can attribute to my recent anxiety (Hurricane Sandy's aftermath), however, I have not read anywhere what the consequences of taking too much FGHP are. I appreciate your help.

I started taking h2o2 4 mos ago. Started with 3 drops in 8 oz distilled water, and built up to 25 drops 2 x daily. I continue to take the 25 drops 2xdaily. I am 74 years old, 5' 10", 155 lbs, non smoker, work out every day, eat healthy, and on no prescription medication. I have fought cancer since '01 with diet, exercise, and rife machines, also had tuberculosis in '62 with moderate advanced case, hospitalized 4 months, was completely cured and no relapses.

Since taking HP for approx 4 months total, I have had painful boils, and cold and flu like symptoms, but the symptoms have escalated in the last 9 days. I have developed a deep cough, sore throat, very low energy almost like I have a virus or flu bug and can do very little work which I'm normally pretty high energy.

I do not throw up or have any intestinal discomfort. I have no fever, no sinus irritation. But a terrible nagging cough for 9 days. I purchased a Vicks Warm Mist humidifier yesterday to see if it will make me feel better, and stop the coughing, return my energy level.

Do I have a toxic build up? What would you suggest to get my energy back??

We had been using food grade hydrogen peroxide in a humidifier for many months.

My nearsightedness has suddenly gotten worse for near distance, for example, signs in supermarkets. My boyfriends' eyes have gotten a lot worse in conditions of glare and haze, he had photosensitivity before but it has become a big problem.

We stopped using the hydrogen peroxide in the humidifier because that is the only new variable.

Does anyone know if hydrogen peroxide caused these problems? At no time did our eyes feel irritated or did I feel he was putting in too much. If damage was caused, what would reverse it?

I just started taking H2O2 (35% FGHP). I am at 5 drops twice a day. I noticed red eyes yesterday, I am not sure if it is because of H2O2 or something else. In a few days, I am planning to go for 6-10 drops 3 times. I will update results.

Has anyone ever had red eyes from taking the dosage three time a day. I started getting red eyes when I hit six drops a day.

Warning

Heavy metal interaction with H202 caution. I had been happily using h202 for several months, then started have concerning heart palpitations, though I was not linking this in any way to h202. I live in an area with high naturally-occurring arsenic in the water supply. A neighbor mentioned that most filters do not filter out arsenic and that I should be buying drinking water. This little tidbit caused me to look up arsenic poisoning - which fit my symptoms exactly: headaches, confusion, drowsiness and heart arrythmias. The latter is where the h202 caution comes in. I read that "arsenic in cells stimulates the production of h202. When h202 reacts with certain metals such as iron or manganese, it produces a highly reactive hydroxyl radical, " which can cause neurological imbalances and disruptions in the electrical-voltage complex of the heart, resulting in disruptive intervals in the QT (that's that lovely little bio-battery we all have that keeps our heart beating at regular intervals). I stopped taking h202 immediately and stopped drinking my water. I have begun a heavy metal detox (I am also having old mercury/silver fillings removed right now) and will complete this before I go back on the h202. I think it important that, if readers have been exposed to metals or other harmful toxins, they may want to consult with health care providers about h202 interactions before proceeding with its use.

Hi Ted
This is Sunny from India. I am a 35 year old woman with two kids aged 7 and 31/2 years. After my second son is born I got severe hyper pigmentation and Melasma and also my immunity came down and I put on 10 kg s of weight. I get frequent colds and cough which are so severe that I used to be on bed for at least two days a week. Then I saw Earth clinic and started Food Grade H2O2 therapy and also Baking Soda. I am using right now from past four months and I want to stop now as my sicknesses came down drastically. But one side effect is that my face and neck has turned to almost black after I started using H2O2 and Baking Soda. In a country where skin color and complexion is given predominant importance I am not even able to step out of the house. I tried many cosmetic treatments like laser, peels which only further aggravated my problem. They told me to avoid working with computer as it sends UV rays and increases pigmentation. They gave me many suggestions to avoid sun through windows also at home, avoid going out in the car too in daylight even with sunscreen. These are so impractical for my lifestyle and anyhow I am avoiding direct sun exposure. My rest of the body is a shade better as usual but it is also darkened a little after using H2O2. Only my face, neck and feet are very hyper pigmentated. So my now only hope is alternative and folk remedies. So Ted please help me why all this happened. Does H2O2 aggravate hyper pigmentation? Now my only help is YOU. So please reply at your earliest convenience. Thank you

Kind Regards
Sunny

I have tried Hydrogen peroxide as it supposedly has many cures, so I was using it to clean my teeth. I gargled with it one morning and 4 hours later almost ended up in the emergency. I had so bad pains that I never experienced in my life, I thought it was having something worse than a heart attack. It was like heartburn, tightness, everything mixed together. Well after 2 hours it subsided and I then went to my doctors for a complete physical, which still taking tests. He realized then I must of swallowed some of the stuff and luckily it did not do more damage. It could've burned right through my insides. He thought I was crazy to do this. Never again will I use the stuff. Please do not use it for teeth or internally at all. I warn you all. Thanks Laurie

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?

Thanks,
David

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 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?

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?

Pam

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?

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...

Warning

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...

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)

Caution drinking Hydrogen Peroxide: I tried drinking less than a quarter capful of Rite Aid brand 3% hydrogen peroxide this morning in a 12 oz glass of water. I immediately felt my body tingling and I drank another glass of water to dilute the effect. Within minutes I felt a weird sensation and had to rush to the bathroom. I have been rushing to the bathroom practically all morning. I did not know whether to laugh or cry because I suffer from chronic constipation and I thought I welcome the frequent bathroom visits but not due to an upset stomach. I drank another glass of water and continued feeling funny. I went to Rite Aid and spoke to the pharmacist who told me I should be okay. I felt better after having a late breakfast. I have a sensitive stomach and I was told the HP may have been too much of an irritant for it. Just a word of caution if you are going to use 3% like I did for the first time, maybe you should start with one drop and see the effect or diarrhea and a racing pulse may be the side effect for a while. It is now about five hours later and I feel almost normal.
