Cordyceps (Cordyceps sinensis) is a fungus (mushroom) from China and particularly Tibet. In nature it is a parasite that attacks caterpillars and other bugs, leisurely devouring its host. After some time the fruiting body breaks through the victim's head to disperse its spores. Because the natural mushroom is quite rare and expensive it was formerly reserved for the Chinese Emperor. Commercial Cordyceps is now grown on soy. Each tablet contains Cordyceps 500mg. Inert ingredients include maltodextrin, starch, silica, cellulose and vegetable Magnesium stearate.
Cordyceps is most famous as the energy and endurance mushroom.
