“There are over 680 documented species of the sac fungus genus Ophiocordyceps, and one of the best known of these is Ophiocordyceps sinensis, colloquially known as caterpillar fungus. The fungus is known in Tibetan as yartsa gunbu or yatsa gunbu. O. sinensis is known in the West as a medicinal mushroom and its use has a long history in Traditional Chinese medicine as well as Traditional Tibetan medicine. The highly valuable fungus-caterpillar combination is hand-collected and is used as an aphrodisiac and as a treatment for a variety of ailments from fatigue to cancer”. – Wikipedia
