Cordyceps (冬蟲夏草) is widely known in Traditional Chinese Medicine (TCM) as an aphrodisiac and have a long history as medicinal fungi. The earliest clear record is a Tibetan medical text authored by Zurkhar Nyamnyi Dorje in the 15th Century outlining the tonic propensities of Yartsa gunbu (Cordyceps sinensis renamed now to Ophiocordyceps sinensis), especially as an aphrodisiac. Although there are often-repeated claims of thousands of years of use in traditional Chinese medicine, so far no clear textual source has surfaced.
