Cordyceps sinensis is a mushroom that grows in the Himalayan mountains of the Tibetan Plateau region. It is known by the name "Chinese Caterpillar Fungus" because it is a parasite that grows in the wild on the larva of the ghost moth.
Demand for this mushroom for use in extracts for Chinese medicine is strong both in coastal Chinese cities, as well as, in more recent years, for world export, and it has become a significant cash crop in the Himalayas.
There are many species of the cordyceps. However, the cordyceps sinensis is the most significant in terms of worldwide demand. It is sold in a number of forms including whole-dried for use in cooking, capsule, powder and liquid.

Things you need
- Live cordyceps sinensis extracts
- Silk worm residue
- Rye grain
- Plastic bags, glass jars
- Temperature, humidity control equipment
Place cereal grain, such as rye, in a dry plastic bag or glass jar. Make sure to sterilise with hot water or other method beforehand. While cordyceps sinensis grows on moth larva in the wild, it can also be grown in other hosts such as rye grain, millet or rice. Rye or millet produces a higher quality product than rice.
Additionally, in China or countries other than the United States, a high quality product can be obtained using silk worm residue from dead silk worms. While these are easy to obtain in China and Japan, they are regulated in the United States and most growers there use grains. Silk worm residue from dead silk worms produces a higher quality product than does use of grains.
Inoculate the substrate of rice, millet, rye or silk worm extract, with the cordyceps sinensis fungus. Temperature should be 20.0 to 23.3 degrees C. There should be diffuse light and atmospheric oxygen conditions comparable to sea level. Growth under these conditions should be for 28-30 days.
Move the fungus and substrate in its glass or plastic containers to a controlled environmental chamber with 50 per cent oxygen, and 50 per cent nitrogen, carbon monoxide and carbon dioxide. The temperature should be thirty-seven degrees F with no light. The fungus should grow under those conditions for 15-20 weeks.
Harvest and process the mushrooms. The chemical composition of the cordyceps sinensis grown under these conditions will be almost identical to that in the wild. The mushrooms should be dried and can be sold as it is to consumers, or for processing into powder or liquid for use in the Chinese medicinal market.
