The mushroom

What Is Cordyceps Militaris?

Cordyceps militaris is a fungus with bright orange, club-shaped fruiting bodies a few centimetres tall. In nature it grows on insect pupae in forests across the Northern Hemisphere; the supplement kind is grown in culture on grain or other substrates, which makes it consistent and far more available than wild cordyceps. A 2021 review in the journal Foods describes its long tradition in Asian practice as a tonic, the compounds found in its fruiting bodies and mycelium, and concludes that it deserves to be considered a functional food.

Two species

Cordyceps Militaris vs Cordyceps Sinensis

Cordyceps militaris

The orange species, cultivated at scale. It forms fruiting bodies in culture, so supplements can use the mushroom itself rather than only the mycelium. This is the species on VapoLung's label: organic Cordyceps militaris fruit extract.

Cordyceps sinensis

The wild "caterpillar fungus" of the Himalayan plateau, now classified as Ophiocordyceps sinensis. It is rare and costly, so most products sold under this name use cultured mycelium strains instead. The two are related but not the same.

What is in it

Cordycepin and the Other Compounds in Cordyceps Militaris

Cordycepin

The best-known compound of C. militaris, a nucleoside studied extensively in the laboratory.

Polysaccharides

Complex carbohydrates found in many medicinal mushrooms, a large part of the dry weight.

GABA

Gamma-aminobutyric acid, an amino acid the review reports in cultured material.

Ergothioneine

A sulfur-containing antioxidant amino acid found in mushrooms.

Compounds as listed in the 2021 Foods review. Most of the research it covers is laboratory and animal work.

Forms

Fruiting Body, Mycelium and Extract: Reading a Cordyceps Label

Fruiting body

The mushroom itself. Labels that say "fruit" or "fruiting body", as VapoLung's does, use this part.

Mycelium

The root-like network, often grown on grain; products may include some of the grain it grew on.

Extract vs powder

An extract concentrates the compounds; a powder is the dried mushroom ground up. "Organic" refers to how it was cultivated.

Research and safety

Cordyceps Militaris Benefits: What the Research Covers

The 2021 review is a careful summary of what C. militaris contains and what laboratory and animal studies have explored, with its traditional reputation as a tonic in Asian practice. Human trials are fewer, so no specific benefit is established for people, and supplement labels use general wording tied to the standard disclaimer. Human safety data are limited as well: use a labeled product as directed, and check with a doctor first if you are pregnant, nursing, under 18, have a known medical condition or take medication.

In VapoLung, organic Cordyceps militaris fruit extract is the fifth and smallest ingredient of the 154 mg blend, alongside mullein leaf, ginger root, bromelain and organic lemon.
