Cordyceps is one of the most valued medicinal fungi in all of Classical Chinese Medicine. Once reserved exclusively for emperors, this versatile mushroom is now the tonic of choice among world-class competitive athletes.

Cordyceps attracted public attention when a group of Chinese runners, who reported using Cordyceps extract to enhance endurance and recovery, broke nine world records in the World Outdoor Track and Field Championships in Germany. Modern clinical applications and research closely mirror those uses described in Classical Chinese Medicine.

Fatigue, adrenal support (similar to ginseng), respiratory health, immune modulation, kidney support, increasing endurance and enhancing performance in athletic training and competition.*

Instructions For Use
Two to four capsules two times a day.

Toxicity, Cautions, Contraindications
No toxicity or side effects are reported in the available literature. Due to Cordyceps' reported platelet aggregation-inhibitory activity,* caution may be advised for those patients using anticoagulants or preparing for surgery. Also, immuno-modulating substances should be used with extreme care or avoided completely in organ-transplant patients utilizing immuno-suppressive agents.

Clinical Research
There has been a significant amount of research done on Cordyceps. Studies have looked at the immuno-modulating and immuno-regulating activities, uses in supporting renal health and respiratory health, and adrenal and glycemic modulation.* 1,2

Traditional Use and Preparation
Cordyceps is sweet and acrid in taste and warm in nature, acting through the lung and kidney channels.3 Cordyceps invigorates the kidneys and protects the lungs.* Cordyceps is also used to replenish the bone marrow and increase blood production, and is used in cases of fatigue, sexual impotence, night sweats, anemia, bacterial infections, and debility after illness.*4 For most conditions Cordyceps is prepared as a decoction, although when used as a tonic in TCM the fruit bodies are often cooked into a chicken broth.5

Active Constituents
Polysaccharides, Cordycepin, Sterols, Adenosine, Cordycepic Acid

Extraction Information
Wild Cordyceps fruit bodies and cultivated Cordyceps mycelium have demonstrated equal levels of immune activity,* neither being superior to the other.6 Most of the modern clinical research has been conducted with hot-water extracts of the cultivated mycelium. The optimal preparation for both is a hot-water or hot-water/ethanol extract.

Our product is a hot-water/ethanol extract from the Cs-4 strain. The mycelium is grown on silkworms, an all-natural chemical-free nutrient base. This process yields all of the active constituents that make Cordyceps one of the most highly prized medicinal mushrooms.

Latin ... Cordyceps sinensis
Chinese ... Dong chong xia cao
Common Name ... Caterpillar Mushroom

Cordyceps is found in the highlands of China, Tibet, and Nepal, above 10,000 feet. In China it is called "winter worm, summer grass" and the "caterpillar mushroom." In the wild, Cordyceps infects insect larvae and mature insects with its spores. The myceliuim then grows inside the body of the host, eventually killing it. A mushroom then fruits from the body of the dead host, always growing from the insect's head. The small slender fruit body resembles a blade of grass and is a half inch to one and a half inches long.
