The Tibetan cordyceps whose name means “Winter worm, Summer grass” is highly valued in tradational Asian medicine. The mushroom grows in the body of a caterpillar until it sprouts from the head. Due to its rarity and difficulty gathering, the prices have increased exorbitantly. To add to the difficulty obtaining this mushroom the Chinese government has warned the fugus is frequently contaminated with arsenic, due perhaps to fallout from air pollution in India in the high plains of Tibet where the mushroom is exclusively found. Peru Biotech have found an alternate source in the pristine Andes mountains of Peru. A sister species, Cordyceps , has been genetically sequenced by the scientists at the Chinese Cordyceps Museum. The results show it is the closest DNA relative to the Tibetan mushroom, and analysis shows it contains similar amounts of cordyceptin, thought to be the active substance. The fungi are bigger, as they parasitise a larger caterpillar than in Tibet. Peru Biotech delivers as promised, though one may have to make allowances for delivery due t the difficulties in harvesting a rare ingredient from a remote area. We are well satisfied with Juan Chavez' service and look forward to reordering from next year's harvest. Richard Kaufman, President, Kingherbs USA Inc.
