Sorry, didn't mean to ignore you, I'll actually be making a post on this soon. But one theme that I keep coming across in all my reading is "if it works on cancer, it works on the common cold." It's an immune adaptor, meaning it'll help your immune system do anything that needs done, from filtering heavy metals (these mushrooms do that naturally), to actually helping your immune system calm down if it is being overactive. A very versatile medicine.
