" a few drops of H202 Food grade hydrogen peroxide, taken in distilled water, will kill and eliminate all candida from the body"

I am not sure that this would be of much benefit.

Hydrogen peroxide is produced in the body by natural processes. It can be toxic through production of Reactive Oxygen Species (ROS). ROS can lead to oxidative damage to body cells. Because of this it is rapidly broken down into water and oxygen by a body enzyme called catalase.
