The Cordyceps Sinensis (Cordyceps sinensis) is a unique entomopathogenic fungus which is one of the basic components of the Traditional Chinese Medicine. It parasites mostly the larvae of the Himalayan Bat Moth (Hepialis armoricanus). It can be found in its natural environments existing only in some Chinese provinces (Tibet, Sichuan) and also in Bhutan and Nepal on cold mountain meadows at elevations from 3,800 to 6,000 m above sea level. Fruit-bodies from natural habitats are very expensive – one kilogram costs up to 100,000 US dollars. Cultivated fungi, or rather the mycelium, of this species which contain quantities of the relevant substances comparable to those of naturally grown Cordyceps, are used in dietary supplements at present.
