A team of researchers from the Institute of Microbiology, Chinese Academy of Sciences (Xiao-Liang Wang and Yi-Jian Yao), summarized all the available information on the insect species associated with the Tibetan medicinal fungus Ophiocordyceps sinensis through an extensive literature survey and analyzed their relationships with the fungus. The study was published in the open access journal ZooKeys.
The fungus has traditionally been used as a tonic to strengthen the human body and in the treatment of kidney and lung problems. It has also been shown to possess a variety of medicinal effects by recent studies, e.g. immunomodulating, hypocholesterolemic, hypoglycemic, anti-tumor, anti-oxidation and anti-aging activities. Natural products of O. sinensis is now sold at a price higher than the gold. The fungus contributes billions of RMB (Chinese yuan) to the rural economy in Tibet Plateau each year and often accounts for some 70% of a local family's annual income. Thousands and thousands of collectors crowd into the Tibet Plateau every summer, causing a sharp decrease in the natural production of O. sinensis and serious damages to the environment.
"Ophiocordyceps sinensis (also Cordyceps sinensis), known as the Chinese Caterpillar Fungus or 'Dong Chong Xia Cao' (winter worm, summer grass) in Chinese, is one of the most widely recognized traditional Chinese medicines. The fungus is endemic to the Tibetan Plateau and has been listed as an endangered species under the second class of state protection since 1999 by the Chinese government. The fungus has a striking developmental biology. As a Sac (ascomycete) fungus, it parasitizes larvae of moths of the family Hepialidae and converts them into sclerotized bodies from which the fungus fruiting body grows. So the natural production of this fungus is closely related to its insect hosts." said the corre
