The Himalayan Powerhouse Goes Mainstream. Cordyceps, which was initially discovered growing on caterpillar larvae in high altitudes in the Himalayas and Tibetan Plateau, has a long history of use in the Traditional Chinese Medicine (TCM) to improve vitality, fight fatigue and increase longevity. Cultivated Cordyceps militaris, the commercially viable analogue of the wild Cordyceps sinensis, is now providing the same incredible benefits, at a sustainable, cost-effective price.
