Cultivated Cordyceps: A Tale of Two Treasured Mushrooms

Ophiocordyceps sinensis and Cordyceps militaris both contain many bioactive compounds that confer potential therapeutic benefits. This review discusses the possible use of cultivated C. militaris as an effective substitute for native O. sinensis in the face of ever-increasing prices of O. sinensis because of its short supply. On the one hand, cultivated C. militaris contains higher levels of cordycepin when compared with that of wild-type O. sinensis and cultivation of C. militaris has been shown to be capable of reducing the risk of heavy metal contamination. On the other hand, there is a paucity of robust in vivo studies and randomized controlled tests comparing the pharmacology and use of C. militaris and O. sinensis. For extraction of cordycepin as western-style tablets, the use of cultivated C. militaris rather than O. sinensis represents the most appropriate future approach. For many other purposes, comparative pharmacology and clinical trials are in urgent needs.
