Each mushroom species collected by Paul from the old growth forests of the Pacific Northwest is sustainably harvested by taking a small sample of tissue with which to generate a master culture. The ecosystem and its mushrooms remain intact and unharmed. We then carefully culture this mycelium for the Host Defense products under strictly controlled laboratory conditions at our facility here in Washington State, supervised by Paul Stamets and his skilled staff.
Fungi Perfecti grows and maintains its cultures using the Stamets P Value® system for quality assurance. The proprietary P Value system ensures the provenance and genetic vitality of each mushroom strain we use. Our verifiable chain-of-custody guarantees the efficacy and viability of the species in the Host Defense line.
