cordycepsCordyceps has been used for a long time in China and Tibet. For at least a thousand years according to the written record. It has always been very highly regarded, but it has also been the most expensive herbal raw material in the world. This is because it only grows at high elevation in the Himalayas around Tibet and Nepal and in small border sections of India and China. The high altitude makes its collection difficult, and this rarity of Cordyceps has limited its use by the general public. The great demand and the limited supply act to drive the price up, sometimes to as much as $35,000 a pound! The scarcity and high price lead many people to try to cultivate Cordyceps like a normal farm product. But unlike the common button mushroom that we find on pizzas worldwide, Cordyceps proved to be extremely difficult to grow.
