Yarshagumba Ophiocordyceps sinensis is commonly called the Chinese Caterpillar Fungus. The formation of Yarsagumba is due to the parasitism of larvae of swift moths, resulting in the development of fruiting bodies which is a highly popular herbal remedy.
After the germination of larvae by a fungus, the latter kills the insect and mummifies it. From the fruit body, a dark brown colour emerges from the dead insect and stands upright, taking the form of yarsagumba.
Yarsagumba is found at 3,500-5,000m above sea level in Himalayan meadows of Nepal, Bhutan, India and Tibet. In Nepal, it is collected from more than 12 districts including Darchula, Dolpa, Jumla, Mugu, Bajang, Rukum, Myagdi, Manang, Gorkha, Rasuwa, Sindhupalchok and Sankhuwasabha.
