Exercise is your body's the best defense mechanism. Increasing circulation is key, also bacteria and all sorts of other shit cannot survive in high-oxygen environments.
Interesting. Well to deal with that I'd drink some ozonated water and/or fast for 24-48 hours. I use all sorts of shit like oregano oil, fasting, apple cedar vinegar, zinc, vitamin C. If you want to incubate inside my body then good luck.
God knows what vaccines do to the body, which is why I don't take them.
Forgot to mention baking soda, but yeah also a great supplement to include in ones diet. Rinsing your mouth with it will cure all sorts of sores and tooth pain too. All the answers are right in front of us, our ancestors knew their shit. Humans are the only mammals that don't fast when they are sick for example.
CONSUME. OBEY. DIE.
