Pachymic acid is a naturally occurring steroid that can be extracted from the parasitic fungus Wolfiporia extensa (synonym Wolfiporia cocos). The dried sclerotia of the fungus is used as a traditional Chinese medicine, and pachymic acid is thought to be the principal bioactive component of it.

Effects

Pachymic acid is known to inhibit the Epstein-Barr virus and to inhibit the snake venom phospholipase A2. It also has antitumor and anti-inflammatory properties.
