Reishi has been used in traditional Chinese medicine for at least 2,000 years.2 The Chinese name ling zhi translates as the "herb of spiritual potency" and was highly prized as an elixir of immortality.3 Its traditional Chinese medicine indications include treatment of general fatigue and weakness, asthma, insomnia, and cough. A Japanese study showed that long-term application of Reishi promoted deep, slow-wave sleep in insomniacs. It has also been used to treat neurasthenia, a condition common in chronic fatigue syndrome. http://www.shilajeet.com/store/Rehi-Mushroom-Powder-45-0-513.html en Sat, 23 Jul 2005 13:10:24 EDT
