Name:
Cordyceps sinensis

Cordyceps sinensis is the fungus found in Tibet above the
altitude of 3800m. It's also called "Yarsa gumba" and "Yarcha gumba".
It's the one that takes over caterpillars, and fetches a VERY high price in Asian markets. Traditional folk medicine uses Cordyceps to treat 21
illnesses such as asthma, erectile dysfunction, cancer, TB, cough and
cold, diabetes. It is said to give people increased health and vitality
and energy by acting as an anti-inflammatory.
Cordyceps shows promise, but more studies
need to be done. Cordyceps is currently harvested non-sustainably from
the wild. I know of no commercial production of Cordyceps.
Medical Health Guide gives more details such as dosage (5-10g daily) and side effects (no major problems have been reported yet.)
