Using Hydrogen Peroxide for Yeast Infections

Curing Candida with Hydrogen Peroxide is a Bad Idea!

A 3% concentration of hydrogen peroxide, like the kind you see in stores, will be strong enough to inhibit Candida yeast. Because the body contains catalase (an enzyme that breaks down hydrogen peroxide), you may need to repeatedly wash an area with this chemical to see better results.

The average 3% hydrogen peroxide should contain about 3 mg of this chemical for every 100 mg of water. A full liter of water is 1000 grams, and a 3% solution of hydrogen peroxide will have close to 30 grams of this chemical in it. The research we will discuss, in this delineation, has shown that you will need approximately 150 mg / L to 3000 mg / L of hydrogen peroxide to effectively inhibit nearly all Candida. Non-albicans species of Candida, can take significantly more hydrogen peroxide to inhibit. Thus, a 3% concentration of hydrogen peroxide is going to be the right strength you’ll need to stop Candida development (30,000 mg / L). But, be careful, hydrogen peroxide can burn the skin and be very, very dangerous if you ingest it (more on this later).

So, due to the hazards of using strong concentrations of this chemical, you would do well to avoid using anything over a 3% concentration. Having burns on the penis or vagina just isn’t worth it. Instead, check out the wide variety of other natural remedies that are proven yeast fighters.

Hydrogen peroxide is a common household chemical that is notably sold in small bottles at a 3% concentration. Specialty retailers may also sell higher concentrations of this chemical—such as 35% hydrogen peroxide solutions. Hydrogen peroxide is, of course, an oxidizing agent; and, is utilized by a number of common products. Chlorine free bleach, household disinfectants, contact lens cleaners, fabric stain fighters, teeth whiteners, and even hair dyes. A very prominent industrial use for this chemical, is using it as a bleaching agent, in the production of pulp and paper. Lactobacillus bacteria can also create hydrogen peroxide; so, adding the right probiotic to your vagina, can allow these bacteria to start churning out this antiseptic chemical automatically.

Hydrogen peroxide is relatively safe to use outside the body; and, should work well when used in the vagina at tolerable concentrations. However, the human body is full of the enzyme catalase. This enzyme is extremely capable of breaking down hydrogen peroxide into oxygen and water. The excess water in the body, from this reaction, is not that dangerous. Yet, when a large amount of free oxygen molecules are present, this can cause a lot of damage. People who have ingested hydrogen peroxide have suffered brain damage; and, if you drink a good amount, you could be hurt very badly. Food that contains too much hydrogen peroxide can cause food poisoning. So, make sure you NEVER ingest hydrogen peroxide. Keep this chemical away from drastic cuts that may allow this chemical to enter the bloodstream.

A study, published in Infectious Diseases in Obstetrics and Gynecology [3.2 (1995): 73-78], sought to see how effective hydrogen peroxide would be at inhibiting Candida strains; and, tried to understand how catalase modified this effect. Catalase, as you know, is an enzyme that breaks down hydrogen peroxide; thus, its presence can limit the inhibiting power of hydrogen peroxide. And, all the strains of Candida investigated by this study, possessed catalase. Bacteria that can produce acid and hydrogen peroxide were also considered as protective agents to ward off vaginal yeast proliferation. Previously, Lactobacilli bacteria, which normally dominate a healthy woman’s vagina, were thought to protect the vagina by producing acid. More recently, it was discovered that some strains of Lactobacilli generate hydrogen peroxide. This is thought to be another reason these bacteria may provide a beneficial effect.

The study found that non-albicans species of Candida had a much higher tolerance for hydrogen peroxide. The researchers reported that non-albicans species had minimum inhibitory concentrations (MIC; i.e., the amount of a substance required to stop the growth of a microbe) about 4 times higher than those of Candida albicans. Oddly enough, there was no discernible correlation between each individual strain’s susceptibility to hydrogen peroxide and the amount of catalase measured. The researchers inferred that stable yeast cells might possess enough catalase to break down hydrogen peroxide that forms internally.

Candida’s catalase is not capable of breaking down substantial amounts of hydrogen peroxide outside of its cells. Hydrogen peroxide may be able to damage Candida cells to the point they rupture; and, thus, catalase is released at this point which was stored inside the cells. The major finding of the study, how much H2O2 is needed to stop Candida growth, revealed that all of the 38 strains tested were successfully inhibited by approximately 149.6 mg / L up to 2993.3 mg / L. Again, non-albicans strains, on average, required a higher concentration to inhibit.

Another revealing study, published in The Open Dentistry Journal [4.1 (2010)], also looked at how well hydrogen peroxide would inhibit various species of Candida. The Candida species investigated included C. albicans, C. parapsilosis, C. glabrata, and C. krusei. The study discussed a dental unit water line, and did not say much about yeast. Yet, the minimum inhibitory concentrations for the Candida species were shown. However, some non-albicans species of Candida were dramatically more resistant to hydrogen peroxide, than their cousin Candida albicans. The following concentrations of hydrogen peroxide inhibited their respective yeast species’ strains in the study:

  • Candida albicans H2O2 MIC ≈ 400 mg / L
  • Candida glabrata H2O2 MIC is over 799 mg / L
  • Candida krusei H2O2 MIC ≈ 200 mg / L
  • Candida parapsilosis H2O2 MIC is over 799 mg / L
  • Candida tropicalis H2O2 MIC ≈ 300 mg / L

The next study also evaluated how well hydrogen peroxide worked at stopping yeast growth. The yeast that was examined by the research was a strain of Candida albicans. This important study was published in the Nigerian Journal of Medicine: Journal of the National Association of Resident Doctors of Nigeria [23.3 (2014): 201-206]. The study used a 35% concentration of H2O2 to see the MIC for Candida albicans. This study also proved that hydrogen peroxide could effectively inhibit Candida albicans.

Cautions for Using Hydrogen Peroxide

A 3% hydrogen peroxide solution will effectively inhibit, and possibly kill Candida yeast cells. Using 3% hydrogen peroxide can also help remove unwanted bacteria from the area you use it on.

A study, published in Toxicological Reviews [23.1 (2004): 51-57], relates the all too real dangers of hydrogen peroxide misuse. According to the study’s authors, hydrogen peroxide causes toxicity in three primary ways: lipid peroxidation (oxidative damage to lipids—and some fats are lipids), damaging tissue via corrosion, and oxygen gas creation. We see, using high concentrations of hydrogen peroxide on sensitive tissues, can result in damage to those areas. Thus, you want to be careful before you use a concentration of hydrogen peroxide above 3% in the vagina. As mentioned, drinking hydrogen peroxide can cause a lot of damage to the body and brain. When a concentration over 35% of H2O2 is ingested, it will break down in the body and release a dangerous amount of oxygen gas. If there is more oxygen than can be absorbed by the blood, an embolism (a blockage of an artery) can result.

If you do happen to drink H2O2, it can aggravate the gastrointestinal system. Common symptoms of this include foaming at the mouth, feeling sick to your stomach, belching, and vomiting. If you use a strong enough concentration in your mouth, you may develop burns in this area. If you get enough of this chemical in your stomach, cardiorespiratory arrest can happen after just a few minutes. The intense amount of oxygen gas that forms inside the body can also cause several blockages of blood vessels in the brain. Additionally, if you are drinking H2O2 in hopes of killing yeast or bacteria in your intestines, this is very unlikely. The presence of the enzyme catalase in the digestive system will rapidly break down the hydrogen peroxide; leaving little, if any, to fight any microbial pathogens.

Another study looked at 325 reported exposures to hydrogen peroxide at a poison control center. The research was published in the Journal of Toxicology: Clinical Toxicology [32.6 (1994): 705-714]. This study also confirms that hydrogen peroxide can cause serious toxic effects. Surprisingly, youth under 18 years of age were involved in 71% of these 325 cases; and, the most common way this group was exposed to hydrogen peroxide was through drinking it (83% of these young people drank this chemical). After people drank hydrogen peroxide, the most frequent side effect was vomiting and nausea. The majority of people who were exposed to H2O2 did not have any severe outcome; but, drinking a concentration of this chemical above 10% did correlate with more severe consequences.

Linda Allen’s Safe, Natural Yeast Infection Breakthrough

Yeast Infection No More Explained solid review.

If you’ve been suffering with repeated outbreaks of genital yeast infections or just want to know how to rapidly get rid of this nuisance infection fast, you may be interested in Linda Allen. Linda Allen was one of the many women who suffered from severe yeast infections. After struggling with the everyday hell that systemic Candida can cause, Linda did arrive at a permanent, safe solution. It took around a decade of hard work and research; but, eventually Linda solved the yeast infection puzzle. Linda’s methods worked so well, they can totally heal genital and oral yeast infections in just 12 hours. Here is a brief overview of her story.

When Linda was in her late teen years she suddenly came down with a sinus infection. About this same time, Linda found that she had a yeast infection. Like many women, Linda made an appointment with her doctor to get herself checked out. The doctor prescribed her a treatment and Linda found that the prescription treatment got rid of her infection. But, a little while later, Linda again found that she had another yeast infection. Linda again made another appointment with her physician and got another prescription. As Linda took the prescription treatment, she found that her yeast infection cleared up without much hassle. As time went on, Linda’s health began to decline, and she was put on increasingly stronger and more powerful antibiotics.

Those who knew Linda wondered if she was a hypochondriac or just in worse shape physically than she let on. With all the money Linda was spending on medical help she couldn’t afford much more than a small, cramped apartment to live in. Things did finally start to go right when Linda went to see a naturopath about her unusual bad health. After seeing Linda, the naturopath told her that she had a systemic yeast infection. This overgrowth of yeast was causing the strange poor health that had been plaguing Linda. Although the naturopath did not provide Linda with a permanent solution to her problem, Linda did get the critical information she needed.

Linda began ardently studying medical writings and investigating Candida. When an informed individual, like a doctor or natural medicine expert, was kind enough to give her some time Linda asked questions and tried to glean helpful keys to remedy her Candida problem. Linda spent around a decade of her life sorting through information on yeast related health problems and solutions. In addition to her studying, Linda also tried several alternative therapies that are used to combat yeast overgrowth. Although what she found didn’t provide her with a clear solution, they did give her pieces of the whole puzzle, figuratively speaking.

Eventually, Linda did compile a new treatment plan that she intended to use on herself. Linda put about a year of time into polishing and refining her novel approach. The day did come when Linda gave her personal therapy a try—on herself of course. Linda found that she didn’t get anymore vaginal yeast infections after she started her treatment. As more time progressed, Linda’s general health began to rapidly improve as well. Linda was again feeling great—like she did before her Candida nightmare began. Linda told a doctor about her program and related the amazing results she had seen. The doctor told her “you may have something here.” Linda then decided to give her new therapy to other people suffering with Candida issues she had met. It wasn’t long before Linda got amazing reports back from these people saying how well her program worked.

Linda has gone on to publish her own book detailing exactly how to follow her powerful treatment and permanently end yeast infection problems. In her book, Linda shows you how to quickly eliminate genital and oral yeast infections in just 12 hours time. And, after a few weeks on her program, you can be totally free from systemic yeast overgrowth. Since Linda published her book in 2004, over 100,000 people from all over the globe have seen amazing results using Linda’s therapy. It is one of the best methods to naturally solve your Candida problem from the comfort of your own home. Linda also guarantees following her book’s plan will cure a genital or oral yeast infection in just 12 hours.
