Well, to cure antibiotic resistant Clostridium Difficile, they use processed poop from patients with normal GI tracts! Yeah, it's something you have to drink. It is brilliant and works.
Keeping the immune system happy involves more than I have hand strength for today.

Juicing is a great way to get nutrients to the body. The immune system needs as many nutrient dense foods as you can give it. Like Chlorella.
