Host Defense emerged from the fusion of skill sets from two experts: Paul Stamets and C. Dusty Yao. Paul’s longtime expertise in mushroom taxonomy and cultivation perfectly complimented Dusty’s years of making herbal extracts. The union - literally - of these two gave rise to Host Defense. Their shared passion for exploring the natural world, from thousands of hours hiking (and laughing) through the Old Growth forest, and their combined ideas created the wellspring that gave birth to the brand and the global mission Host Defense stands for today. Join us as we continue to walk this path of exploration and healing, bridging modern science with ancient tradition.
