Uses and Functions
Cordyceps is a unique and precious fungus, which has been widely used in traditional herbalism. Cordyceps militaris supports a variety of biological activities, including immunomodulation, antioxidant, and anti-aging functions.*
Consistent consumption of Cordyceps helps to strengthen the skeletal structure, and specifically benefits the lower back region, the knees, and ankles. It is traditionally used for minor and temporary backache due to injury, fatigue, stress, or aging.*
Cordyceps sinensis is an invigorant in Chinese tradition and was honored as one of the five greatest invigorants together with Panax Ginseng, Deer Antler, Astragalus root and Eleuthero (Siberian Ginseng). The New Compilation of Materia Medica, a classic herbal text by Wu Yiluo, written during the Qing Dynasty, lists the traditional usage of Cordyceps as a “Yin/Yang double invigorant.” It further states that Cordyceps goes to the Lung and Kidney meridians and is useful for “Lung support” and for “Kidney improvement” (the “Kidney” in traditional Chinese healthcare includes the renal functions, all skeletal structures, bone marrow, the adrenal glands, sexual organs, and the brain itself).
Cordyceps is a major Lung tonic. It can be used to strengthen respiratory power in those who require extra energy in order to perform physical work (e.g., labor, sports, exercise, recreation or sex) or it can be used by those who experience a deficiency of Lung power.* It has been widely used by superior world class athletes.

Cordyceps has always been used as a primary herb to fortify the defensive system of the body, and recent data indicate that Cordyceps is a potent immune system potentiator. Researchers in Japan and China have isolated a number of polysaccharides in Cordyceps which strengthen the immune system. The constituent known as cordycepin plays a major role in fortifying and fine tuning the body’s defenses. Maintaining the immune system is one of the mechanisms involved in healthy aging and helps mitigate dysfunctions typically associated with aging.*
Other studies have shown that Cordyceps can have a benefit in the vascular system as well. Cordyceps has been shown to support healthy blood pressure and to strengthen heart muscle.* Cordyceps improves the function of the micro-circulation and improves efficiency at the capillary level. This is very important to our longevity.
Cordyceps sinensis and militaris are both very highly regarded in China, the Himalayan countries, Japan, and Korea as a tonic for those who are recovering from an illness or an operation, or after giving birth.* In these cases, the Cordyceps helps the patient recover their physical power, improve their appetite, and helps protect the body by developing increased immunological capacity.* It is also a go-to herb for people who have already experienced a trauma or significant stress. Cordyceps directly and quickly helps restore spent Jing of the Kidneys – both Yin (fluids, hormones, neurotransmitters) and Yang (vital capacity, inner power).*
Cordyceps militaris has recently been shown to help with normal blood sugar maintenance.
Cordyceps militaris has been found to have no known cytotoxicity.*
Cordyceps species have been traditionally and broadly used for the enhancement of sexual function by those who can obtain it. It is also considered to be a fertility enhancing herb.
Cordyceps can be added to soups, teas, elixirs, and formulations.
Traditional Health Principles and Uses
Pharmacology of Yin and Yang
Cordyceps is famous for being both a Yang and Yin tonic. A major herbal materia medica written during the Qing Dynasty, lists the traditional usage of Cordyceps as “going to the Lung meridians, being useful as a Lung protector,” and “for Kidney improvement and as a Yin-Yang double invigorant.”
An article from The Hong Kong University of Science and Technology Department of Biochemistry, entitled “Pharmacological basis of 'Yin-nourishing' and 'Yang-invigorating' actions of Cordyceps, a Chinese tonifying herb,” by KM Siu et al, is enlightening.
Here is the published abstract of the article, published in 2004:
“Cordyceps sinensis (Berk.) Sacc. (Cordyceps), a popular Chinese tonifying herb, was revered for being both 'Yin-nourishing' and 'Yang-invigorating' in Chinese medicine. In order to establish the pharmacological basis for the 'Yin-nourishing' and 'Yang-invigorating' action of Cordyceps, the effects of wild and cultured Cordyceps on concanavalin A (Con A)-stimulated splenocytes, an in vitro bioassay for 'Yin-nourishment', and myocardial ATP generation capacity, an ex vivo bioassay for 'Yang-invigoration', were investigated in mice. The results indicated that methanolic extracts of wild and cultured Cordyceps enhanced both the Con A-stimulated splenocyte proliferation in vitro and myocardial mitochondrial ATP generation ex vivo in mice, with no significant difference in potency of action between the two types of Cordyceps. While the immuno-potentiating effect was associated with the increase in interleukin II production, the stimulation of myocardial ATP generation was paralleled by an enhancement in mitochondrial electron transport. When compared with typical 'Yin' and 'Yang' tonifying Chinese herbs, Cordyceps was found to possess both 'Yin-nourishing' and 'Yang-invigorating' activities. The pharmacological characterization of Cordyceps by means of contemporary bioassays is consistent with the time-honored clinical observation from Chinese herbalists.”
A Powerful Yang Kidney Tonic
Traditionally, wild Himalayan Cordyceps and Cordyceps militaris are used for the purposes of strengthening the primal Kidney functions, which include sexual functions, brain power, structural integrity (bones, joints and connective tissues), wound healing and recovery ability.*
Jing is the primordial “Inner Power” of the body and mind. We are born with a certain amount of Jing, which determines approximately how low we can live. Jing is depleted as we live, and is further depleted by stress, disease and extreme challenge. This loss of Jing is believed in Asian health philosophy to shorten our lives. Fortunately, the Jing we lose by living a robust (or stressful or dangerous) life can be replenished by the consumption of Jing tonifying herbs. This is one of the great secrets of longevity. The most famous of these Jing tonifying herbs are Cordyceps, Eucommia bark, He Shou Wu, Goji berries, Morinda root, Epimedium and a few others. As great as all these herbs are, Cordyceps is definitely at the top of this list – accounting for its extreme value.
As a sexual tonic, Cordyceps is considered to be one of the best. Like the other major Yang tonics such as Deer Antler Tips (tips are the last 1 inch of the antler, literally the tips), Epimedium (“Horny Goat Weed”), Desert Cistanche, Morinda (“Strength Builder”), Eucommia bark and wild Cynomorium root and herb (“Ever Young Herb”), it has a profound long-term strengthening capacity, and of course, may be used along with the other Yang tonics.
Nevertheless, many people claim that Cordyceps is the most powerful aphrodisiac of them all! It is used by both men and women.*
Cordyceps seems to promote fertility (which reflects inner vitality and Jing). Cordyceps has been shown to support innate spermatogenic function in males, and studies indicate it may significantly improve sperm motility. Animal studies indicate that it increases testosterone and estradiol-17 concentrations, but not other hormones such as FSH (follicle stimulating hormone), LH (luteinizing hormone) or prolactin. Thus, supplementation with Cordyceps is widely thought to improve sperm quality and quantity.*
Consistent use of Cordyceps is traditionally used to help strengthen the skeletal structure, and specifically benefits the lower back region, the knees and ankles. It supports the other joints as well. It is traditionally used for minor and temporary backache due to injury, fatigue, stress or aging. The bone is the “house of marrow.” Marrow quality and health plays a determinative role in human health and longevity, as stem cells for the whole body reside in the marrow. Marrow plays a key role in blood health, immune cell regeneration, kidney functions and hormone-mineral balance. Cordyceps is being intensely studied with regard to all these functions.*
A word to the wise – every depleting episode of our lives should be accompanied by the consumption of some Cordyceps. If you know you are about to embark on a significant challenge, take Cordyceps. While you are going through the challenge, take Cordyceps. Afterwards, take Cordyceps to help recover. And remember, the Cordyceps you consume today will not only be beneficial today and tomorrow, but will have also benefits in the later years of your life.
Watch Ron talk about Inner Power - Jing:
A Powerful Qi Tonic
Qi is our vitality. This vitality animates our muscles, blood flow, organ functions and all bodily activity, including that of the brain. It is produced in the body from the nutrients we consume and the air we breathe. Therefore, the Lungs and the Spleen-Pancreas-Stomach complex (the digestive system) are considered the primary organs associated with energy accumulation, production and replenishment. Cordyceps strengthens both the lung functions and the digestive functions. As a result we produce more Qi.
Cordyceps has long been recognized in Chinese traditional health practice as a primary herb to fortify the defensive system of the body. Dozens of studies have shown that Cordyceps sinensis and Cordyceps militaris have profound beneficial effects on our immune functions, helping to protect us from the dangers of the natural environment in which we live every moment of our lives, and even more so in crowded spaces of unmasked revelers, in cities, on planes or in wild jungles.
Circulation is important in all fields of health care. Studies have shown that Cordyceps can have a benefit in the vascular system. Cordyceps has been shown to support healthy blood pressure and to strengthen heart muscle. However, Chinese healthcare puts extra emphasis on the micro-circulation – more than does western health care does. There is an important saying in Chinese health care: “Qi leads Blood.” The vitality of the circulatory system at the microcirculatory level is controlled by our Qi.
Weak Qi. Poor circulation is a consequence of weak Qi. Cordyceps has been shown to improve the function of the micro-circulation and improves efficiency at the capillary level. This is very important to our health and longevity. Combining Cordyceps with Red Salvia and/or Dang Gui root accentuates the circulatory benefits of both herbs.
Cordyceps is very highly regarded in China as a tonic for those who are recovering from an illness or an operation, or after giving birth. In these cases, the Cordyceps helps the patient recover their physical power (Jing) and their overall Qi. Cordyceps helps improve their appetite of those who are in a weakened state, and it helps protect the body immunologically.
When combined with both Jing and Qi tonic herbs, Cordyceps has a broad, all-encompassing power to improve human functioning.
Hear Ron talk about Yin and Yang below:
A Powerful Shen Tonic
A wild and hardy herb such as wild Cordyceps naturally has a ton of spirit. It is capable of handling sub-zero weather, extreme wind, and blizzard conditions, high intensity ultraviolet light and much more. Those who consume it feel a surge of inner power, mental clarity, and sharpening of the senses. The Himalayans and other Asian connoisseurs of wild Cordyceps consider it a potent wisdom-supporting herb, one that vivifies the life spirit that we call Shen. It is considered a “happy herb,” – that is, those who take it feel a sense of awe, and even a sense of satori. Cordyceps, however, it not considered to be a psychoactive mushroom. The Shen tonifying effect is cumulative upon continued use.
Combining and Safety
Cordyceps combines very well with all major tonic herbs. When blended with other Qi tonics such as Ginseng (Asian and American), Reishi mushroom (Ganoderma species), Astragalus root, Schizandra berries, Goji berries, Gynostemma leaf, Mountain Ant and/or Codonopsis root, Cordyceps’ Qi-building power is increased as the synergy of the various herbs results in an even more powerful tonic.
When blended with other Jing tonics such as He Shou Wu, Goji, Eucommia, prepared Rehmannia, Ever Young Herb (Cynomorium), Epimedium and Morinda, Cordyceps will have even more capacity to build Jing.
When blended with other Shen tonics such as wild Ginseng (Chinese and/or American), Reishi, Pearl powder and Albizia flowers, the power of Cordyceps is accentuated.
Cordyceps is commonly blended together with Blood tonics like Dang Gui and Goji berries, and also with blood vitalizers like Red Salvia and Carthamus flower. Cordyceps is frequently combined with Snow Lotus flower, which also grows at the Himalayan snowline and is one of the most powerful, effective and safest detoxification herbs in the world.
Cordyceps combines very well with many nutraceuticals like resveratrol, nicotinamide riboside (NR), Astragaloside IV, Tanshinone IIa (from Red Salvia), ginsenosides from Ginseng, green tea polyphenols, L-theanine (from green tea), and Quercetin, etc.
Cordyceps has no known toxicity. It has also been widely used for over a thousand years (probably for much longer). However, those with established mushroom allergies should use all mushroom products with extreme caution and under the guidance of a professional herbalist and/or physician or professional nutritionist.*
Cordyceps is safe for most people, straight into the mouth or as an ingredient in an herbal tea, elixir or food. [† See Precautions section for rare exceptions].
Cordyceps is also considered safe and beneficial for dogs and cats (in their food). In fact, until Cordyceps became world renowned and became a valuable economic commodity, the Himalayan nomads and herdsmen would encourage their pack animals and herds to forage on Cordyceps-rich grasslands when at the snowline, and would add it to their feed in order to increase their vigor and longevity. [Please introduce this and all herbs to your pet’s diet judiciously, in small doses, so that you can detect any allergic responses (highly unlikely). If you believe your pet is not responding in a positive way, simply cease providing this supplement to your pet].
