Definitely don't drink a 35% solution of H202. It will most likely kill you. I am fairly well researched on Hydrogen peroxide. I have also used it in other non growing related experiments.
Some say it's a miracle cure, others say it's a snake oil. I have read about people using diluted solutions through an inhaler to help clean and oxygenate the lungs. Also others that involve oral consumption, direct injection and topical therapy. The only known deaths have occurred from people inadvertently drinking a 30%+ solution thinking it was water.
There aren't a lot of studies in regards to its benefits and side effects as no drug companies can profit from it.
Hydrogen peroxide is man made but it is also formed in the environment and is present in rain water.
It has been said that oral consumption breaks down the H202 in the stomach causing problems rather than benefits.
I recommended that you only use an extremely diluted solution of food grade H202. The 3% Drugstore type solutions contain undesirable stabilizers.

This website seems to be pro H202. There are many that aren't.
