What is the official website of Cordyceps Naqu? How about that medicine?

Cordyceps Naqu grows on the plateau at an altitude of 45~6 meters in Naqu area of Tibet Plateau. Cordyceps sinensis, referred to as Cordyceps sinensis, is a fungus parasitic on the larvae of Cordyceps sinensis and developed in summer. Cordyceps sinensis got its name. The real cordyceps sinensis are all wild. In summer, worm eggs are laid on the ground, and after a month or so, they hatch into larvae and then drill into the wet and soft soil layer. A fungus sporangium in the soil invades the larvae and grows in the larvae. After a winter, when the next spring comes, fungal hyphae begin to grow, and in summer, they grow out of the ground and look like a grass. In this way, the larva's body and fungal hyphae together form a complete "Cordyceps sinensis". The fungus spore takes the insect body as food and grows rapidly. The insect body is generally four to five centimeters, and the fungus spore can grow to the length of the insect body within one day. At this time, the Cordyceps sinensis is called "head grass" and has the best quality. On the second day, the spore of the fungus grew to about 1.5 times of the insect body, which was called "Chinese grass", and the quality was second; After three days, the spore grows to twice or even more than the length of the worm, which is called "tail grass" and the quality is the worst.

not all cordyceps sinensis have medicinal effects. The cordyceps sinensis with real medicinal value recognized by medicine comes from two top producing areas in China: Naqu in Tibet and Yushu in Qinghai.
