Reishi (Ganoderma lucidum) and cordyceps (Cordyceps militaris) extract powders, even at extremely high daily doses for 3 months, showed no harmful effects in lab tests on rats. The mushrooms, grown under controlled conditions on organic oats, packed impressive levels of beneficial compounds - reishi contained 29% of the immune-boosting beta-glucans, while cordyceps had 37%, plus the energizing compound cordycepin.
