Over the millennia, Cordyceps has been treasured in Asia as one of the most effective natural tonics and body harmonizers. It mysteriously grows in the winter as a parasite fungus feeding off caterpillars and as grass in the summer through its emerging fruiting body, making it known as ?winter worm , summer grass?.

Because Cordyceps is only found in China's Southwest highlands (3,000~5,000 meters high), it is deemed a priceless entity. Now, we have closely replicated its natural growing conditions, at low temperatures and in the presence of proprietary rare elements, and we use freezing extraction that preserves carefully all the bio activities. This unique process gives our Cordyceps a tasteful, unmatched quality.

Contains no lactose, starch, preservatives, artificial coloring or flavoring , and no yeast.

Suggested Usage:1~2 capsules twice a day.

Storage:Keep dry and cool; avoid sunlight; keep cap tight.

60 capsules per bottle

    Cordyceps Sinensis

    The Cordyceps sinensis craze first started in 1993 when 2 female Chinese athletes, within the span of a week, shattered the world records for track & field's 1,500 meter race, 3,000 meter race and 10,000 meter race. Such unprecedented performances raised immediate suspicions. Steroids and other performance enhancing drugs were tested for but the subsequent results came back negative. Repeatedly questioned as to why these 2 athletes outperformed everyone else by such a large margin, their coach finally revealed that in addition to rigorous training and dedication, the women were given a secret elixir made from Cordyceps sinensis.

    Cordyceps sinensis is a fungus that's been used to treat a multitude of diseases for at least 1,000 years. The herb of choice for treating kidney and lung ailments, it is said that Cordyceps sinensis goes directly to these organs and enhances their functions.1

    In Chinese medicine, the kidneys are known as the "roots of life" since all of the body's other organs are completely dependent on the kidneys for their life activity. Nephrotic Syndrome, erectile dysfunction, sterility and reproductive problems are brought about when the kidneys don't function properly.

    Qi, which is one's life energy, is thought to be ruled by our lungs. Qi normally flows through the lungs without impairment but weak lungs and certain illnesses can impede Qi's continuity. When one's Qi isn't emanating properly, one's life force is bound to be drained. Occurrences such as bronchitis, fatigue, a decreased libido and other ailments become much more likely.

    Cordyceps sinensis treats the lungs and kidneys directly which is why there are multifarious health benefits associated with this prize fungus. Recent studies and clinical trials have suggested that Cordyceps sinensis has the vast potential to improve a variety of conditions, including the ability to inhibit cancer. Although the results have been positive, Cordyceps sinensis is still a fairly new introduction into western medicine and more studies are warranted to gauge the full extent of its abilities.

    What exactly is Cordyceps Sinensis?

    Cordyceps sinensis is a fungus that only grows in the high altitudes (9,000 - 14,000 feet above sea level) of China's & Tibet's mountain ranges, namely the Himalayas. The term "Cordyceps" refers to the genus of parasictic fungi that germinates and feeds on the bodies of insects. Cordyceps sinensis germinates specificially in caterpillars.

    During the winter, the fungus grows inside the body of the caterpillar, feeding off its body and absorbing its nutrients. The mycelium invades and eventually replaces the host tissue, while the elongated fruiting body sprouts from the caterpillar and releases the fungus' spores into the air, further infecting other nearby caterpillars. Chinese medicine focuses on the encapsulated mycelium since that is the portion of the fungus that contains the most medicinal properties.

    What to look for when purchasing Cordyceps Sinensis

    One of the biggest obstacles to growing Cordyceps sinensis is its extreme growing conditions. Cordyceps sinensis is very specific when it comes to its nutrients, choosing to only feed on caterpillars. Furthermore, it'll only grow in the extreme climates of the Himalayan mountains. Therefore replicating it's growing conditions had been a huge obstacle.

    When purchasing Cordyceps sinensis, be sure to look for whether or not the formulation consists mostly of the fungus' mycelia or fruiting body. As is the case with most fungi, most of the beneficial properties are concentrated in the mycelium.

    Another key point is the actual manufacturing process of each capsule. Cordyceps sinensis, like most food, has natural enzymes. Enzymes are highly beneficial to digestion and other physiological functions. However they are highly unstable and they die when temperatures surpass 104?F. Therefore, low-temperature, freeze-drying technologies are necessary to preserve all of the fungus' bio activities.

    Wild grown Cordyceps sinensis is extremely rare and the Chinese government has made it illegal to harvest the fungus due to environmental concerns. Genuine wild grown Cordyceps sinensis is only available on the black market and costs more than $9,000 a kilogram. It's suffice to say that any company claiming its product is naturally harvested needs to be carefully investigated. In addition, it's debateable whether naturally harvested products are more potent than lab cultured mycelium. Naturally harvested products suffer from inconsistencies due to pollution, inclimate weather, poor soil and other environmental factors while lab cultured mycelium is germinated in controlled environments using the highest quality strains.

    Cordyceps sinensis In the News - 3rd Party Research Reports and Articles*

    • Boost energy with cordyceps: this Chinese fungus helps athletes go further 2 [show/hide]
      After the 1992 Olympics, Chinese athletes attributed their wins to their use of the fungus (Cordyceps), which sparked American interest...

      One double-blind study, published in the American Journal of Clinical Nutrition in February, tested the energy and endurance of 110 healthy sedentary adults. In it, half took 3 g of cordyceps daily while the other half took a placebo. After 12 weeks, the cordyceps group could bicycle 2.8 percent longer than they could before taking the supplement, while the placebo group decreased the length of their rides by 5.6 percent.

      In a double-blind study published in Medicine & Science in Sports & Exercise last year, researchers gave 30 male athletes either 4.5 g of cordyceps daily or a placebo. The athletes did not change their exercise routine during the study. After six weeks, the cordyceps group's oxygen intake was almost double the placebo group's. This increased oxygen intake helped their bodies work more efficiently.

      In another study published in the same journal in 1999, 30 healthy elderly Chinese people took either 3 g of cordyceps daily or a placebo. After six weeks, aerobic capacity in the cordyceps group increased 9 percent, which researchers say produced higher energy levels, while those taking the placebo saw no energy change.

      Researchers don't know exactly how cordyceps boosts energy and endurance. They theorize that it may help your body use energy more efficiently by increasing blood flow to your liver and other organs and by improving your oxygen use. Cordyceps's antioxidant activity may alleviate fatigue.

    • Polysaccharide from Cordyceps sinesnsis may protect against hydrogen peroxide-induced injury. 5 [show/hide]
      Cordyceps Sinensis, a well-known traditional Chinese medicine, possesses anti-tumor, immunostiumlant and antioxidant activities; however, the identities of active componenets have not been determined. Through previous studies, we've isolated a polysaccharide(CSP-1) from Cordyceps sinesnsis which protects against hydrogen peroxide-induced injury. CSP-1 produced a significant drop in blood glucose levels in diabetic rats. The studies suggest that CSP-1 may stimulate pancreatic release of insulin and/or reduce insulin metabolism.

    • Mushroom medicine boosts endurance, reduces fatigue 6 [show/hide]
      Today, practitioners of traditional Chinese medicine use it (Cordyceps) to treat respiratory diseases, impotence, and weakness in the back and knees...study found that cordyceps lowered total cholesterol and raised "good" HDL cholesterol levels in rats fed a cholesterol-enhanced diet...other research has shown that it possesses antitumor and immune-enhancing properties...

      Study: In a 12-week study of 131 healthy but sedentary men and women ages 40 to 70, half the group took 3 g a day of a cordyceps supplement; the other half took a placebo. Both groups completed a 1-mile walk before and after the study.

      Results: Those who took cordyceps raised their oxygen capacity (which means muscles have more energy reserves) by 5.5%, making the poststudy walk easier and less tiring. This relatively small improvement suggests that cordyceps may help sedentary people get fitter. The study was conducted at the Rippe Lifestyle Institute, an independent research facility in Shrewsbury, MA, and presented in April at the American Physiological Society's annual scientific conference in Washington, DC.

    • Chinese athletes shatter world records 7 [show/hide]
      AT CHINA'S 1993 National Games in Beijing, Wang Junxia and Qu Yunxia, two unknown women, smashed the world records for 1500, 3000 and 10,000 metres. Their coach, Ma Junren, was besieged by athletes and journalists eager to know how the athletes had achieved such incredible results, which have not been bettered to this day. Their success, he said, was down to the "revitalizing" properties of a fungus (Cordyceps Sinensis) that has been used in Tibetan and Chinese medicine for 2,000 years. Since then, a surge in demand for the fungus has led to environmental damage in the Tibetan plateau where it grows.
