Folklore and History

According to legend, yak herders in the Himalayas of Tibet and Nepal noticed that when their Yaks grazed on a certain mushroom (cordyceps) they suddenly become very energetic and playful. The herders investigated what the Yaks were eating and the strange and mysterious cordyceps caterpillar-mushroom was discovered.

The first written record of cordyceps was made during the Tang Dynasty (620AD). Cordyceps quickly becomes prized by the ruling emperors of China for its healing and longevity properties. Physicians of the Ming dynasty are said to have used cordyceps to make powerful tonics. From the 1400's onwards, Tibetan scholars wrote extensively about cordyceps.

Cordyceps were brought to Europe by a French priest who was a guest of the Chinese Emperor when he was introduced to cordyceps and their revitalizing powers. In 1757 Cordyceps made its first appearance in a European medical text - New Compilation of Materia Medica. From that point on, scientist have been fascinated by the health properties of the cordyceps sinensis mushroom.

Cordyceps sinensis is just one member of the massive Cordyceps family which has over 400 members. All cordyceps are endoparasitoids and have similar, life cycles. Basically, cordyceps spores infect a host insect and finally take over. The stroma (fruiting body) of the fungus sprouts from the insects brain. Each species of cordyceps invade only a single species of insect. Cordyceps sinensis invades the larvae of the Chongcao bat moth which hibernates for the winter underground in a cocoon. The mycelium of the cordyceps sinensis mummifies the body of the larvae whilst it is asleep and when the spring comes a single thin stroma sprouts from the head and pushes upwards like a single blade of iridescent blue grass. Land rich in cordyceps can apparently be easily identified - that's where the yaks prefer to graze!
