Our dietary supplement Cordyceps Cs-4 contains a specific extract of the fungus or mushroom Cordyceps sinensis. Little-known in the West, this fungus is native to Asia where it grows primarily at an altitude of over 4000 metres in the mountainous regions of Tibet, Nepal, Bhutan, China and India. Despite the quite specific conditions in which it grows, it has been used for several thousand years in traditional Asian systems of medicine.
What are the benefits of Cordyceps sinensis?
Cordyceps sinensis has been used therapeutically for millennia. In traditional Chinese and Tibetan medicine, it is regarded as an invigorating food, excellent at fortifying the body. It is also used to help with certain cardiovascular, kidney, respiratory and nervous problems. In addition, research has shown that taking Cordyceps sinensis may be associated with benefits for the immune system.
As a result of its exceptional properties, Cordyceps sinensis is much valued in the sporting world for its particular benefits for improving physical performance. This mushroom sprang to fame at the World Athletic Championships when the Chinese female athletes won almost all the endurance events and broke several records. Their coach attributed their success to “intensive training and a diet high in Cordyceps”. According to the magazine Track & Field News, “the Chinese athletes made the greatest quantum leap in the history of human performance”. Since their achievements, Cordyceps sinensis has regularly been the subject of scientific studies published in specialist journals. It’s safe to say, we’ve not heard the last of this mushroom!
Scientific progress has meant that the Cordyceps sinensis mushroom is now available to buy in dietary supplement form. Our new supplement is formulated from the main variety of Cordyceps sinensis: Paecilomyces hepiali Chen, also known as Cs-4. Available in bottles of 120 vegetarian capsules, this product has a recommended dose of two to three capsules a day.
What do the studies say about Cordyceps Cs-4?
Given its therapeutic potential, a number of research studies have been conducted on this exceptional fungus. At the end of the 1970s, the Institute of Materia Medica in Beijing launched a major, 10-year research programme on Cordyceps sinensis which produced a number of key advances. In 1985, Chinese scientists succeeded in developing a brand new fermentation method for producing Cordyceps Cs-4. Two years later, this product was approved as a class 1 traditional treatment by the Chinese Minister for Health. This authorisation followed a number of clinical trials conducted on a total of 1800 subjects, the results of which showed that Cordyceps Cs-4 may help:
- Promote physical strength and endurance in patients suffering from respiratory or cardiovascular disease.
- Reduce oxidative damage by trapping free radicals.
- Increase levels of intracellular ATP and use of oxygen.
- Encourage healthy lung function.
- Relieve symptoms in patients with respiratory disease, particularly asthmatics.
- Improve tolerance to the cold, especially in elderly patients.
- Improve the overall condition of patients with fatigue.
- Increase levels of SOD.
- Increase aerobic capacity in healthy elderly patients.
