Cordyceps
Cordyceps militaris / Ophiocordyceps sinensis
Once so rare it was reserved for emperors.
Wild cordyceps grows only above 3,000 meters on the Tibetan Plateau, formed through a rare parasitic relationship between a fungus and a caterpillar.
It's referenced in old Chinese and Tibetan medical texts, and was historically exclusive to imperial use given its extreme rarity in the wild.
Nearly all cordyceps sold today is lab-cultivated Cordyceps militaris, grown on a grain substrate rather than wild-harvested from a caterpillar host — a meaningfully different product from the traditional wild form.
A high-altitude tonic for lungs and stamina.
In Traditional Chinese and Tibetan medicine, cordyceps is traditionally used to support lung and kidney function, stamina, and daily vitality.
This reflects historical use of the wild fungus, not a claim about the cultivated form sold commercially today.
How it has been, and is, prepared.
Traditional: Wild fungus-caterpillar complex prepared as a decoction.
Modern: Lab-cultivated Cordyceps militaris, sold as capsules, powder, or extract.

Common questions on cordyceps.
Is supplement cordyceps the same as wild cordyceps?
Usually not — most commercial products use lab-cultivated Cordyceps militaris rather than the rare wild Ophiocordyceps sinensis.
Is cordyceps vegetarian?
Lab-cultivated Cordyceps militaris is grown on a grain substrate, not on an insect host, unlike the traditional wild form.
Why was wild cordyceps historically so expensive?
Its extreme rarity and difficulty of harvest at high altitude made it one of the most valuable substances in Chinese medicine.
