Cordyceps sinensis is a nourishing Chinese medicine. Together with natural ginseng and velvet antler, it is listed as three major tonics, which can treat kidney deficiency, waist and knee pain, shortness of breath and night sweats.

I haven't heard that it can cure toothache.

The price is 20,000-25,000 yuan a catty, which is almost 8,000-10000 yuan//.
