I hope to express my concern about Chinese herbal medicine or health care. The word Cordyceps sinensis on WeChat comes from a precious medicinal material in traditional Chinese medicine, also known as Cordyceps sinensis or Cordyceps sinensis, which refers to a kind of Cordyceps sinensis that grows in cold regions and has high medicinal value. This cordyceps sinensis is considered to have the effects of nourishing yin, moistening dryness and improving immunity in traditional Chinese medicine.
