Cordyceps is a genus of parasitic fungi that grows on the larvae of insects. When these fungi attack their host, they replace its tissue and sprout long, slender stems that extend outside the host's body.
The most well-known species, Cordyceps sinensis, has been used in traditional Chinese and Tibetan medicine for centuries. Cordyceps is believed to enhance athletic performance, increase energy levels, and boost immune function. It is also thought to have anti-aging properties.
Available as a dietary supplement, cordyceps is popular among athletes and those seeking to improve vitality and overall health.
