Ophiocordyceps sinensis is an entomopathogenic fungus that parasitizes larvae of ghost moths and produces a fruiting body which is valued as an herbal remedy found in mountainous regions of India, Nepal and Tibet.
The fungus germinates in the living larva, kills and mummifies it, and then the stalk-like fruiting body emerges from the corpse. It is known in English colloquially as caterpillar fungus, or by its more prominent names Yartsa Gunbu (Tibetan: དབྱར་རྩྭ་དགུན་འབུ་, Wylie: dbyar rtswa dgun 'bu, literally "winter worm, summer grass"), or Dōng chóng xià cǎo (Chinese: 冬虫夏草). Of the various entomopathogenic fungi, Ophiocordyceps sinensis is one that has been used for at least 2000 years for its reputed abilities to treat many diseases related to lungs, kidney, and erectile dysfunction. This fungus is not yet cultivated commercially, despite the fact that several fermentable strains of Ophiocordyceps sinensis have been isolated by Chinese scientists.Overharvesting and overexploitation have led to the classification of O. sinensis as an endangered species in China.Additional research needs to be carried out in order to understand its morphology and growth habits for conservation and optimum utilization.
The hosts in which O. sinensis grows are ambiguously referred to as "ghost moths", which identifies either a single species or the genus Thitarodes: they may be one of several Thitarodes that live on the Tibetan Plateau (Tibet, Qinghai, West-Sichuan, SW-Gansu & NW Yunnan), and the Himalayas (India, Nepal, Bhutan).
