Discovered by yak herders in the Himalayan mountain region. Recorded history of the mushroom’s use in Traditional Chinese Medicine started about 1,000 years ago. Traditionally recommended for various ailments and for energy. In the last few decades knowledge of the mushroom has progressed significantly. Once the most expensive edible food substance in the world and only available to the upper class recent cultivation techniques have changed this. In the last 13 years indoor cultivation methods have produced cordyceps that are bio-identical to ones found in the wild but stronger in health constituents and lower in environmental toxins. Nutritionally the most concentrated form of naturally occurring Adenosine, cordyceps have been proven to increase cellular energy by allowing the cells in the body to use oxygen more efficiently.
