Plant Part Used



Cordyceps is a unique black mushroom that extracts nutrients from and grows on a caterpillar found in the high altitudes of Tibet and China. Even though it is difficult to find and harvest, cordyceps is one of the most valued medicinal agents in the Chinese medical tradition.

Fortunately for consumers, a patented lab fermentation process has allowed large-scale production and availability of cordyceps. While it has served for centuries as a general tonic for promoting longevity, vitality, and endurance, it is now being researched for its potential for increasing energy, aiding respiration, treating kidney disorders, and more.

Reported Uses

Cordyceps’ ability to increase vitality and respiratory health is linked, studies suggest, to its role in improving the availability of oxygen to the lungs and bloodstream. (1) These functions could prove useful for the treatment of asthma and bronchitis.

In addition to supporting the respiratory system, cordyceps may help the body ward off certain types of cancer. Studies have suggested that the mushroom can decrease the reproduction of cancer cells. (2) , (3) , (4) , (5) Cordyceps has also been used to help alleviate some of the side effects of chemotherapy and radiation therapy. (6)

Cordyceps has also affected the activity of the immune system. Numerous studies show opposite results. Depending on the part of cordyceps studied, either immune system stimulation or immune system suppression was noted. (7) , (8) , (9) , (10) , (11) Uneducated use of cordyceps in people with diseases affecting the immune system, including people using medications to either stimulate or suppress their immune system could cause serious problems with their therapy.

Other studies have focused on Cordyceps’ role in supporting kidney function. It is believed that cordyceps may help facilitate the processes by which toxins are processed in the kidneys, while strengthening the overall health of the organ. (12) , (13) , (14)

Cordyceps’ role as an antioxidant, as well as its possible role in supporting cardiovascular health, are also part of its list of potential benefits. One study suggests that cordyceps increases the body’s supply of an enzyme that hunts down free radicals. (15) This may explain its role as an antioxidant. The risk of atherosclerosis may be lowered by cordyceps because of its ability to reduce blood cholesterol levels in some studies. (16)
