Internal peroxide is pretty strong stuff and I suggest you read OXYGEN OXYGEN OXYGEN first and then don't do it. "IF" you fill you must, always take it on an empty stomach is the golden rule and if you take it anytime you risk stomach cancer.
Olive Leaf and Oregano and sunshine on all your body is more than enough for mold control. The metals will haunt you the rest of your life, I suggest lots of ocean herbs daily and kidney type herbs and start cleansing the metals out.
The chest? Daily use of a leg shaker and the sitz bath will do wonders and at age 75 or 175 anyone can due both of these with almost no effot. The sitz bath will correct the flow and the leg shaker will do wonders for your bones and muscles as they rebuild.
The chest? ANYTIME you feel this, take a pinch of deep earth salts in your mouth and then swallow 3 glasses of home made distilled water and this can be made into fruit juice or herbal tea as well. Most problems such as this are related to dehydration.
Self-Experimentation is great, but if Peroxide is not a human food, then it is always risky to eat such things. If you use 70% peroxide your ready to make rocket fuel!!!
