Cordyceps Sinensis is found in Nepal Himalayas above 3800m. sea level. It is high valued traditional medicine. It is created when a type of fungus parasites the larvae of the Chongcao Bat. Moth and forms a fungus (larva) composite body. The larva forms a cocoon in the winter and hibernates in the ground. Because the fruiting body of the fungus emerges from the head of the larva in the summer time and trembles a grass sprout, this medicine's local name means roughly ' Yarcha Gumba (winter bug, summer grass)' As per customer required
