Hydrogen peroxide scientifically also known as H202 is a common and widely used disinfectant, that has surprisingly a variety of good uses and benefits.

The discovery of hydrogen peroxide was first described in the 18th century by the French chemist Louis Jacques Thénard.

Thénard made this happen by producing and treating barium peroxide with nitric acid, making hydrogen peroxide.

This process of Thénard’s was used from the end of the 19th century until the middle of the 20th century.

What is hydrogen peroxide made of?

In terms of look, hydrogen peroxide is a colorless viscous liquid, only that much more viscous than water. On application, it actually looks exactly like water.

Another widely used benefit of hydrogen peroxide is its powerful oxidizing properties.

What will react with hydrogen peroxide?

These properties and compounds allow the hydrogen peroxide to work as a bleaching agent making it good for anyone who needs to bleach their hair, as peroxide reacts with melanin to oxidize it and convert it into a compound that is free of color.

In fact, interestingly enough Hydrogen peroxide’s same oxidizing properties allow it to react with bacteria, viruses, spores, and yeasts, making it a great way to disinfect as well as being an overall disinfection.

An improved version of this process used hydrochloric acid, followed by addition of sulfuric acid to precipitate the barium sulfate byproduct.

Hydrogen peroxide is considered a “singlet oxygen therapy” because it releases a single atom of oxygen when it comes into contact with other substances, which is called an oxidation reaction.

This process is believed to be the key to understanding how hydrogen peroxide flushes and detoxifies our system as well as prevent free radical occurrence that can spur cancer and other complicated health concerns.

When a single oxygen atom is released within your body, it is highly reactive and will oxidize or reduce the molecular structure of undesirable and harmful organisms.

These organisms can be such as bacteria, fungi, viruses, parasites and foreign proteins, as well as diseased tissue for those who suffer from diabetic conditions.

Once the oxygen atom is released, hydrogen peroxide breaks down to water or H2O.

This high-energy form of oxygen, represented as O1, displays a greatly enhanced healing capacity compared with the regular oxygen you breathe, which is known as O2.

The significant difference between O1 and O2 can be tremendous as O1 can greatly impact the immune system, giving a rise and a boost to stem off infections as well as complications.

Biological Benefits of Hydrogen Peroxide

A research study published by “Nature” found that hydrogen peroxide plays a role in the immune system.

The Scientists who took part in the research found that hydrogen peroxide presence inside cells increased after tissues are damaged.

This amazing find was conducted on the zebrafish and showed what is thought to act as a signal to white blood cells to converge on the site and initiate the healing process.

The research showed that when the genes required to produce hydrogen peroxide were in fact inactivated, the white blood cells that act to heal did not accumulate at the site of damage.

Although these experiments were conducted on fish it should be clear to everyone that fish are genetically similar to humans as our DNAs almost match.

Within this, the same process is speculated to occur in humans in terms of the hydrogen peroxide effectively working to restore immunity support.

This immunity support of hydrogen peroxide can extend itself from pathogens, viruses, germs, cuts, and as well as infections such as sinus infections.

Clinical studies showed that hydrogen peroxide demonstrates broad-spectrum efficacy against viruses, bacteria, yeasts, and bacterial spores.

Within the study in “Nature”, it suggested that asthma patients have higher levels of hydrogen peroxide in their lungs than healthy people.

This also proved the fact that could explain why asthma sufferers have inappropriate levels of white blood cells in their lungs.

The study also showed that hydrogen peroxide has important roles as a signaling molecule in the regulation of a wide variety of biological processes.

The complex property is a major factor implicated in the free-radical theory of aging.

The free radical theory of aging also known as “FRTA,” states that all organisms age due to the fact that cells accumulate free radical damage over time.

In theory, a free radical is any atom or molecule that has a single unpaired electron in an outer shell.

This theory is based on how readily hydrogen peroxide can decompose into a hydroxyl radical, as well as how superoxide radical byproducts of cellular metabolism can react with water to form hydrogen peroxide.

The problem is that these hydroxyl radicals in turn readily react with and damage vital cellular components, especially those of the mitochondria.

Another study has some even going on to state that they believe that hydrogen peroxide can also cause cancer in people as well, although the study is inconclusive.

Is hydrogen peroxide toxic?

If ingested, solutions of hydrogen peroxide up to concentrations of 9% are generally nontoxic; however, even a 3% solution is mildly irritating to mucosal tissue and may cause vomiting and diarrhea. Ingestion of industrial-strength hydrogen peroxide causes systemic toxicity and has been associated with fatalities.The only grade of the substance hydrogen peroxide that should be used for home or personal use is food grade.

Food Based hydrogen peroxide

The only grade substance of hydrogen peroxide that should be used for home or personal use is food grade hydrogen peroxide.

In fact! This form is typically a concentration of 35% and is significantly more potent than what is often sold in stores and supermarkets.

There are many different grades of hydrogen peroxide that are made and intended for different uses such as:

  • 5% Pharmaceutical Grade. This is the grade sold at your local drugstore or supermarket. This product is not recommended for internal use. It contains an assortment of stabilizers that shouldn’t be ingested. Various stabilizers include acetanilide, phenol, and sodium stannate and tetrasodium phosphate.
  • 6% Beautician Grade: This is used in beauty shops to color hair and is not recommended for internal use.
  • 30% Reagent Grade: This is used for scientific experimentation and also contains stabilizers. It is also not for internal use.
  • 30% to 32% Electronic Grade: This is used to clean electronic parts and not for internal use.
  • 35% Technical Grade: This is a more concentrated product than the Reagent Grade and differs slightly in that phosphorus is added to help neutralize any chlorine from the water used to dilute it.
  • 35% Food Grade: This is used in the production of foods like cheese, eggs, and whey-containing products. It is also sprayed on the foil lining of aseptic packages containing fruit juices and milk products. THIS IS THE ONLY GRADE RECOMMENDED FOR INTERNAL USE.
  • 90%: This is used as an oxygen source for rocket fuel.

For example, electrical grade hydrogen peroxide actually includes chemical stabilizers to prevent it from decomposing.

Food grade hydrogen peroxide, in short, can be used for a variety of reasons such as:

  • Treating sinus infections
  • Cleansing wounds and preventing infection
  • Eliminating parasites
  • Reducing toothache
  • Detoxing the skin and body
  • Killing microbes in the body, in the air, or on surfaces to prevent disease

It should be noted that although hydrogen peroxide is a safe and effective compound to use, food grade peroxide must be diluted before use.

Can you have an allergic reaction to hydrogen peroxide?

Allergic reactions to any properties or compounds truly depend on each individual. For the majority, in dilute concentrations of open wounds hydrogen peroxide can prevent infections, however on healthy skin hydrogen peroxide may cause irritation. So in general one should take precautions when starting or trying anything new.

Hydrogen Peroxide Uses

Hydrogen peroxide is the only germicidal agent composed only of water and oxygen. Even with that simplicity, astonishingly it kills disease organisms by oxidation.

It is also considered one of the worlds safest all natural effective sanitizer.

In fact, hydrogen peroxide kills microorganisms by oxidizing them, which can be best described as a controlled burning process.

Hydrogen Peroxide Teeth

When it comes to the benefits of hydrogen peroxide for teeth it can be broken down into a few different sections.

The first benefit of hydrogen peroxide teeth is for the toothbrush. In fact soaking your toothbrush in hydrogen peroxide will keep the brush free from germs and viruses.

This method is especially great and needed after coming off of a sickness such as the cold and flu.

The next great thing about hydrogen peroxide teeth is its ability to whiten your teeth pretty well.

The hydrogen peroxide plays well in treating the enamel of the teeth as well as treating the surroundings and cavities of our teeth.

Within a few short weeks, you will be able to see a significant difference in terms of brightness and whiteness of the teeth.

The peroxide able to act as a deep cleaner, going deep into the enamel and bed of the tooth, lifting off coffee stains and unwanted yellowness.

Also using baking soda mixed with hydrogen peroxide will have a tremendous impact on getting rid of stains.

Another added benefit of hydrogen peroxide is its ability to be used as toothpaste. This can be great for those who want to use a more holistic approach when it comes to their oral health.

In fact the majority of brand name toothpaste have added chemicals and fillers that can greatly impact our health down the road.

You can also use baking soda and hydrogen peroxide to make a paste for brushing teeth.

Hydrogen peroxide also helps with early stages of gingivitis as it kills bacteria, and can also impact excessive gum bleeding.

Mixed with salt and baking soda, hydrogen peroxide works as its own set standard whitening toothpaste.

In fact, I’ve had a better return on investment when I’ve used this formula to whiten my teeth instead of over the counter whitening solutions.

Hydrogen peroxide can also impact toothaches, as it can act as an anti-inflammatory.

Also, it serves as a mild anti-inflammatory, so it relieves pain associated with toothaches and other common conditions.

It also treats and eradicates any germs or infection that are causing the ache.

Hydrogen Peroxide for Sinus Infections

Sinus infection is inflammation of the air cavities within the passages of the nose. Sinusitis can be caused by infection, allergies, and chemical or particulate irritation of the sinuses.

It should be noted that sinus infections couldn’t be passed on to someone else. Sinusitis may be classified as an acute sinus infection, subacute sinus infection, chronic sinus infection, infected sinusitis, and noninfectious sinusitis.

Used as a sinus infection treatment, hydrogen peroxide functions to eliminate the underlying infection. It clears the nasal passages and kills any existing germs to prevent further progression of the condition.

Hydrogen Peroxide for Wounds

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin.

They often happen because of an accident, but surgery, sutures, and stitches also cause wounds.

Minor wounds usually aren’t serious, but it is important to clean them.

One of the most common uses of H2O2 is a wound sanitizer. When applied to a wound, the product reacts with the organic matter in the lesion and oxidizes to kill any germs and prevent infection.

Hydrogen Peroxide for Parasites

Unfortunately, over 85-95% of the population has some form of parasite and chances are that they don’t have any clue.

A parasite is any organism that lives and feeds off of another organism. Some examples of parasites include roundworms, tapeworms, pinworms, whipworms, hookworms, and more.

Because parasites come in so many different shapes and sizes, they can cause a very wide range of problems.

Some consume your food, leaving you hungry after every meal and unable to gain weight.

Others feed off of your red blood cells, causing anemia. Some lay eggs that can cause itching, irritability, and even insomnia.

If you have tried countless approaches to heal your gut and relieve your symptoms without any success, a parasite could be the underlying cause for many of your unexplained and unresolved symptoms.

As in the other treatment forms, when taken internally, hydrogen peroxide adds oxygen to the body’s internal environment.

This oxidized environment is one in which parasites cannot exist, so they are naturally eliminated from the body.

Hydrogen Peroxide for Detox

Detoxification is what your body does naturally to neutralize, transform or get rid of unwanted materials or toxins. It is a primary function of the body, constantly working and interacting with all other functions of the body.

The detoxification system is a key component of our body’s functioning. Most of the molecules made by our bodies every day are for getting rid of waste products.

Eliminating any toxins in the body is an important step to overall wellness.

Hydrogen peroxide can be used as a detoxification agent to eliminate several different forms of toxins.

Hydrogen Peroxide for Cancer

Cancer a term used for diseases in which abnormal cells divide without control and are able to invade other tissues is a diagnosis that unfortunately has become more common in our world.

Cancer cells can spread to other parts of the body through the blood and lymph systems.

Cancer is not just one disease but also many diseases. There are more than 100 different types of cancer.

Cancer is one of the newest applications that have been discovered for hydrogen peroxide.

In this case, it oxidizes the unhealthy cells to eliminate cancer without harming the good healthy cells.

Hydrogen peroxide can be utilized in a number of ways. While the external application is the most common form of treatment with hydrogen peroxide, the product can actually be used internally when in a diluted form.

Hydrogen Peroxide for Hair Lightening

If you tend to want to highlight your hair during the summer or any other season but prefer to steer clear of harsh chemical lighteners, there is a great use and benefit in trying out hydrogen peroxide.

Hair Lightening Peroxide is a bleaching agent and is used for lightened hair. Dilute 3% Hydrogen peroxide with water (50 / 50) and spray the solution on your wet hair after a shower and comb it through.

You will not have the peroxide burnt blonde hair like the hair dye packages, but more natural highlights if your hair is a light brown, faddish, or dirty blonde.

What you will want to do is dilute hydrogen peroxide half and half with water as well. Apply as directed above and test after 15-20 minutes.

Peroxide will lighten quickly without the worry of drying out like commercial hair bleaches. Wash out well after you get the shade you want.

Hydrogen Peroxide for Contact Lenses

If you’re anything like me it can get frustrating always running to the store to buy contact solutions.

Hydrogen peroxide acts as a strong disinfectant and can work just as well as leading contact solutions.

In fact, contact lenses with hydrogen peroxide can be used as a disinfectant such as any vision’s clear care no rub contact lens cleaning solution.

Hydrogen peroxide has its ability to break down the proteins that build up on the lens from the eye’s immune response, resulting in increased comfort for those with sensitive eyes.

Hydrogen Peroxide for the Dishwasher

To disinfect your dishwasher, add 2 oz. of 3% Hydrogen peroxide to your regular washing formula.

Hydrogen Peroxide for the Kitchen/Household Surfaces

You can clean your counters and tabletops with hydrogen peroxide to kill germs and leave a fresh smell.

Simply put a little on your dishrag when you wipe, or spray it on the counters. Fill a spray bottle with a 50/50 mixture of 3% Hydrogen peroxide and water and keep it in every bathroom to disinfect without harming your septic systems like bleach or most other disinfectants will.

After rinsing off your wooden cutting board, pour or spray hydrogen peroxide (and then vinegar) on it to kill salmonella and other bacteria.

Keep a spray bottle of 3% (straight) to disinfect the interior of the refrigerator and kids’ school lunch boxes.

You can also use hydrogen peroxide to clean glass and mirrors with no smearing. Use it in the bathroom to sanitize the counters, toilets, floors, etc.


It is best to use two spray bottles rather than mixing the solutions together.

Put straight vinegar in one and straight Hydrogen peroxide in the other spray bottle. When you want to sanitize a surface (cutting board, counters, sink, cages, toys, toilets, floors, etc.) spray one mixture on the surface, then the other.

When they mix, for a brief time the chemical action of the two make a very powerful sanitizer.

You can rinse off the surface afterward. This applies for kitchen surfaces as well as vegetable and food decontamination.

Hydrogen Peroxide as Humidifiers

Use 1 pint 3% hydrogen peroxide to 1 gallon of water in a humidifier or steamer.

Hydrogen Peroxide for Washing and Laundry

You can also add a cup of hydrogen peroxide instead of bleach to a load of whites in your laundry to whiten them.

If there is blood on clothing, pour directly on the soiled spot. Let it sit for a minute, then rub it and rinse with cold water.

Repeat if necessary. Peroxide is a perfect alternate solution to keep those clothes white.

Also, when chlorinating clothes, they tend to wear out faster – peroxide won’t do that.

Hydrogen Peroxide for Stain Removing

3% Hydrogen peroxide is an effective stain remove if it is used fairly soon after a spill, although even blood stains as old as 2 days have been successfully lifted with Hydrogen Peroxide.

If a little peroxide is poured onto the stain it will bubble up in the area of the blood, due to a reaction with catalase.

3% H2O2 must be applied to clothing before blood stains can be removed with hot water.

Cold water and soap can then used to remove the peroxide treated blood.

It should be noted that Hydrogen peroxide will bleach or discolor many fabrics.

Hydrogen Peroxide for Food Preparation

Hydrogen peroxide can work effectively as a food preparation as well as decontamination.

With a combination of vinegar and hydrogen peroxide, it can make a cheap, effective and non-toxic disinfectant agent and is said to be more effective at killing pathogens than bleach on its own.

In fact, it is non-toxic, so you can use it to cleanse cooking and food preparation areas as well as fruits and vegetables.

In tests run at Virginia Polytechnic Institute and State University, pairing Vinegar and Hydrogen Peroxide mists kills virtually all Salmonella, Shigella, or E. coli bacteria on heavily contaminated food and surfaces.

For this reason, hydrogen peroxide has become an integral part in many restaurants and buffets.

Hydrogen Peroxide for Vegetable Soak

You can use the mixture as a vegetable wash or soak to kill bacteria and neutralize chemicals.

Add 1/4 cup 3% H2O2 to a full sink of cold water. Soak light skinned (light lettuce) 20 minutes, thicker skinned (like cucumbers) 30 minutes.

Drain, dry and refrigerate. Prolongs freshness. If time is a problem, spray vegetables (and fruits) with a solution of 3%. Let stand for a few minutes, rinse and dry.

Key Takeaways

It should be noted that only 35% Food Grade hydrogen peroxide is recommended for internal use.

At this concentration, however, hydrogen peroxide is a very strong oxidizer and if not diluted, it can be extremely dangerous or even fatal.

Any concentrations over 10% can cause neurological reactions and damage to the upper gastrointestinal tract.

Hydrogen peroxide can be an effective compound and tool to keep around for its many uses and benefits.
