What is Hydrogen Peroxide?

Hydrogen peroxide has a chemical formula very similar to water (H2O). It only has an additional oxygen atom, so its formula is H2O2. This extra atom allows hydrogen peroxide to break down quickly into oxygen and water. This is a great advantage because it can be done so quickly, which means it’s harmless and very safe.

Hydrogen peroxide is found in all living beings. It is produced by white blood cells to fight bacteria and other harmful agents. Similarly, plants, such as fruits and vegetables, regularly produce hydrogen peroxide. In fact, this is one of the reasons why fruits and vegetables are so healthy.

Hydrogen peroxide also boosts immune system. It is found in rain, which makes plants grow faster. Also, it’s one of the best natural cleaners and can be used in the household for various things.
