Jarrow Formulas Organic Cordyceps is cultivated from the wild cordyceps strain found at high altitude in the Himalayan Mountains of Nepal and is harvested at the mycelium stage of growth. The biomass of the entire growing medium and mycelia in this product provide a broad spectrum of physiologically active compounds. Cordyceps has been traditionally used in Chinese medicine for strengthening Qi (energy).* The modern use of cordyceps includes energy enhancement; stamina and immune function.* Residual powder on the tablet surface is a normal result of the organic manufacturing process; and does NOT affect product performance.
