Western Siberian

Agarikon (Laricifomes officinalis) has one of the longest documented medicinal use histories of any organism — described by Dioscorides (~65 AD) for tuberculosis and fevers, and maintained in Western pharmacopoeias for nearly 2,000 years until the early 20th century. Agaric acid was listed in the US and British Pharmacopoeias as an antisecretory agent. Paul Stamets' modern screening program identified potent in vitro activity against orthopoxviruses (smallpox surrogates), influenza H5N1, and Mycobacterium tuberculosis — a striking potential validation of the ancient tuberculosis indication. However, no human clinical trials exist. The species is endangered in Europe due to old-growth forest loss and slow growth (individual conks may take decades to centuries). Modern research and commerce should rely exclusively on cultured mycelium.
