Cordyceps sinensis is listed as three major supplements in the history of traditional Chinese medicine with ginseng and velvet antler. It has the sayings of “three major treasures of Chinese medicine, ginseng, antler, and cordyceps”. Interestingly, these three treasures are the Chinese people who have been circulating as the top-level nourishing medicine for hundreds of years. More coincidentally, these three treasures are just the “typical” representatives of the three major categories of the biological world – plants, animals, and microorganisms; Cordyceps sinensis also enjoys the reputation of “Oriental Legendary Treasures” internationally.
