I’ve recently been researching and experimenting with local medicinal fungi. In particular the woody polypores that grow on trees and logs in this area. These fungi are part of traditional medicine in China, Nepal, and also the Pacific Northwest (PNW). It turns out that in both Nepal and the PNW these same fungi have been used as shamanic masks. See http://forestpathology.cfans.umn.edu/pdf/Fungi_Magazine_Polypore_Masks_2017.pdf This is peculiar because there was little (no?) contact between the cultures of Nepal and the native cultures of the PNW. BTW- These polypore’s are hard woody fungi, and many of them are large. They contain complex water soluble sugars (polysaccharides) and alcohol soluble triturpinoids. In order to extract these compounds the mushrooms need to be cut up into small pieces, and a khukuri is the ideal tool to do this. After cutting with a khukuri I toss them into a high powered blender to further mince them for efficient solvent extraction.
