Immune boosting super food, most powerful super food known to man on Earth, makes goji, acai, pomegranates, blueberries look like peanuts. Helps with diabetes, asthma, allergies, high blood pressure, psoriasis, cancer, etc, Chaga mushroom. Area in Siberia where it has been consumed for hundreds of yrs as tea or coffee, cancers and tumors are virtually non-existent. You can buy chunks, powder or pill form. I went out and found my own, it grows around here, on birch trees. Right now is the time to harvest it. I also found some Reishi mushrooms, another super duper food, to late for the reishi though but I now know what they look like and where to find them. There is no poisonous look alike of either, there is no known poisonous polypore fungi anyway. Anyone who has spent time in the woods has probably seen both, I didn't know either.
I was surprised first trying Chaga tea, no fungi flavor, tastes like a mild green tea, very pleasant.
