Cordyceps militaris is the orange, club-shaped fungus behind every Cordygen product. This guide brings together what it is, how it relates to Himalayan Kida Jadi, how it is grown, what scientists have studied, and how to compare products. It is written by the team that cultivates Cordygen in Rau, Indore.
What is Cordyceps militaris?
Cordyceps militaris is a fungus in the order Hypocreales and the family Cordycipitaceae.1 In nature it grows on insect pupae in forests across the Northern Hemisphere, producing slender orange fruiting bodies a few centimetres tall. Unlike many of its relatives, it can be grown indoors on a prepared substrate without an insect host, which is why it is one of the most widely cultivated Cordyceps species.
The part most people eat is the fruiting body: the orange strands, harvested and dried. It is sold whole, ground, or as an extract.
What is Kida Jadi?
Kida Jadi (कीड़ा जड़ी, "insect herb") is the Indian name for the Himalayan caterpillar fungus, Ophiocordyceps sinensis. It grows on ghost moth larvae high in the Himalaya and is collected by hand each spring. It is scarce and expensive, and most of what is traded is wild-collected. Our Kida Jadi guide covers it in detail, including price and what to check before buying.
Cordyceps militaris vs Cordyceps sinensis
The caterpillar fungus used to be called Cordyceps sinensis. In 2007 a large molecular study reorganised the group and moved it to the genus Ophiocordyceps, in a different family from C. militaris.1 So the two are related, but they are different species.
| Cordyceps militaris | Ophiocordyceps sinensis (Kida Jadi) | |
|---|---|---|
| Family | Cordycipitaceae | Ophiocordycipitaceae |
| Appearance | Bright orange, club-shaped | Dark brown stalk on a larva |
| Source today | Mostly cultivated indoors | Mostly wild-collected |
| Insect host in commercial product | No (when cultivated on substrate) | Yes |
| Cordycepin | A major source; levels vary with strain and conditions3 | Measured about five times lower than natural C. militaris in one comparison2 |

Fruiting body vs mycelium
A fungus has two main parts. The mycelium is the thread-like network that grows through the substrate. The fruiting body is the visible structure that grows up from it. With C. militaris the fruiting bodies can be lifted cleanly off the substrate and dried.
Some Cordyceps products are made from mycelium that is dried and milled together with the grain it grew on, so the powder can contain substrate as well as fungus. Neither label is automatically better, but you should know which one you are buying. All Cordygen products are made from fruiting bodies: Raw is the whole dried fruiting body, and our Capsules and Tincture use fruiting-body extract.

How Cordyceps militaris is cultivated
Research reviews describe a common sequence for growing C. militaris fruiting bodies:3
- Liquid culture – the fungus is first grown in a liquid medium to build up healthy, even inoculum.
- Inoculation – the liquid culture is added to containers of solid substrate; cereal grains such as rice are the most common base.
- Dark incubation – the containers stay in the dark, typically for one to two weeks, while mycelium colonises the substrate.
- Light-induced fruiting – light–dark cycles, cool temperatures and high humidity trigger the orange fruiting bodies to form.
- Harvest and drying – mature fruiting bodies are cut and dried.
Strain, substrate, light and temperature all change how much of each compound the finished fruiting bodies contain, which is why products from different growers can differ.3
How Cordygen grows Cordyceps militaris
Cordygen is grown and packed by Shnikh Agrobiotech Private Limited, a DPIIT-recognised agri-tech startup in Rau, Indore, Madhya Pradesh (FSSAI Reg. No. 21426850004712). Our growth room follows the same three-stage flow, which is written on its wall: liquid culture → dark phase → light phase.
- Liquid cultures are grown in flasks on a laboratory shaker.
- Inoculated containers incubate in the dark until the substrate is colonised.
- They then move to multi-tier racks under LED lighting in an air-conditioned room, where the fruiting bodies develop.
- The harvested fruiting bodies are dried and packed as Cordygen Raw, or extracted for Vital Capsules and the Tincture.

Cordycepin and other compounds researchers study
C. militaris naturally contains several compounds that are the subject of scientific research:4
- Cordycepin (3′-deoxyadenosine) – a nucleoside closely related to adenosine; the compound most associated with C. militaris research.
- Adenosine – a nucleoside found throughout living cells.
- Polysaccharides – complex carbohydrates from the fungal cell wall.
- D-mannitol – a sugar alcohol, historically called "cordycepic acid".
- Ergosterol and carotenoids – a fungal sterol and the pigments that give the fruiting bodies their orange colour.
Most studies on these compounds have been done in cell cultures and animals, and reviewers note that more clinical research is needed.4 Research on an organism or an isolated compound does not show that any particular product will have a specific health effect. Cordygen products are food supplements and are not intended to diagnose, treat, cure or prevent any disease.
Raw vs capsules vs tincture
| Raw | Vital Capsules | Tincture | |
|---|---|---|---|
| What it is | Whole dried fruiting body | Fruiting-body extract in HPMC capsules | 1:5 fruiting-body extract in water and food-grade ethanol (≤10%) |
| Pack | 30 g jar | 60 × 500 mg | 30 ml dropper bottle |
| Suggested use (label) | 1–2 g daily | 1 capsule twice daily after meals | 1–2 ml, 1–2 times daily |
| Good for | Tea, warm water, cooking | Work and travel | A flexible liquid routine |

How to choose a Cordyceps product
- Check the species. The label should name Cordyceps militaris or Ophiocordyceps sinensis, not just "Cordyceps".
- Check the part used. Fruiting body, mycelium, or an extract of one of them.
- Look for an FSSAI number and the manufacturer's name and address.
- Read the ingredient list. Dried whole Cordyceps should list only the fungus; extracts should state what else is in the capsule or liquid.
- Follow the label dose and speak to a doctor first if you are pregnant, nursing, on medication or have a medical condition.
- Be wary of cure claims. Food supplements in India may not claim to treat or cure disease.
