Pure Cordyceps (Hirsutella sinensis): Cordyceps capsules are the ideal supplement for supporting lung health and improving oxygenation, increasing energy levels, and improving stamina and endurance. Research also indicates Cordyceps can reduce symptoms of depression, increase testosterone in men, promote fertility in women, improve focus, and reduce inflammation.
Cordyceps sinensis is the most highly prized ingredient in Traditional Chinese Medicine, priced at up to $4,000 an ounce due to their rarity and difficult wild harvesting process in the high altitudes of the Himalayan Mountains. Unlike the other Cordyceps supplements available on the market which are comprised of the less expensive Cordyceps militaris, we have sourced this from a supplier who has replicated the natural environment to cultivate wild Cordyceps (Cordyceps sinensis), resulting in a strain of Cordyceps proven to be 99.645% identical to wild Cordyceps, according to rDNA sequence analysis (ITS 1, ITS 2 and 5.85rDNA).
Though Cordyceps has only recently exploded in popularity in the west, it has a long history of use in Tibetan and Chinese medicine. The first mention of Cordyceps in medical literature comes from the 15th century Tibetan medical tract Ten Million Instructions: A Relic, where it is mentioned as a remedy for ailments of sexual virility. Due to its limited availability, Cordyceps did not become known in China until as late as the Qing dynasty. The first mention of the medicinal comes from the 1713 volume “Annals of Sichuan” in which it was purported to be “warm in nature and restorative of the vital essences”. Subsequent Chinese materia medica would all generally emphasize Cordyceps effectiveness in chronic lung conditions and its potency as a virility-enhancing drug.
In modern times, the celebrated Chinese physician Li Ke (李可) used Cordyceps as a key medicinal in his formulas for treating people recovering from diseases of the lungs such as chronic bronchitis and pulmonary fibrosis. It is thus no surprise that the Journal of Science and Healing recommended cordyceps as a key medicinal in convalescence from Covid-19, citing its ability to improve ventilatory capacity and reduce airway inflammation.
After Chinese long-distance female runners shattered world records in 1993 and 1994 with the help of Cordyceps sinensis supplements, research into the caterpillar fungus exploded in the west. In the following we’ll detail some highlights from this bevy of research with regard to three particular actions: exercise performance enhancement and anti-fatigue, anti-inflammation and sexual health.
Exercise Performance Enhancement and Anti-Fatigue
Sexual Performance Enhancement and Infertility
