On grasslands of Himalayan Plateau
lives a caterpillar that according to legend, can transform itself from animal to plant and back again. Tibetan herders discovered thousands of years ago that when yaks ate the fruiting bodies of the plants that grow from the head of caterpillar larvae, they seemed to have more energy to climb the mountain trails.
Winter Worm Larvae and Fungus |
The herb, Cordyceps sinensis, is the name of the fungus that grows on caterpillar larvae. In its native habitat, the spores of Cordyceps infect and get into the body of caterpillar larvae. When the fungus grows in the body it kills the larvae in the winter, and eventually fungus fully consumes the larvae and sprouts into a little plant in the summer. The Chinese name Dong Chong Xia Cao literally describes the life cycle of Cordyceps. Cordyceps sinensis (Dong Chong Xia Cao, 冬虫夏草) or Yartsa Gubu (Tibetan) is perhaps the rarest and most precious herb in traditional Chinese medicine. Cordyceps has been used for the general health well being by Chinese for centuries, but remained unknown for the rest of the world until in 1992 Olympics when the Chinese women's track team athletes broke multiple world records and attributed their success in part to Cordyceps they took as an herbal dietary supplement.
Modern studies suggest Cordyceps may enhance the immune function of our body, may stimulate progesterone production, boost energy and endurance (Rajesh Kumar, P.S. Negi, Bhagwat Singh, Govindasamy Ilavazhagan, Kalpana Bhargava, Niroj Kumar Sethy (2011). "Cordyceps sinensis promotes exercise endurance capacity of rats by activating skeletal muscle metabolic regulators". Journal of Ethnopharmacology 136: 260-266.)
It will be interesting to see how all the athletes, particularly the Chinese woman, perform at the London Olympics. We might discover some more ancient Chinese herbal secrets as a result! Pass the Cordyceps si'l vous plait.
