The decline of bees worldwide is well-documented, as is the threat to crops that rely on them for pollination. Little known is that natural mycelial extracts are being developed which boost bee immunity. According to mycologist Paul Stamets, “Mycelium is the immune system of the mushroom.” Stamets, along with Washington State University scientists and the USDA, found that colonies showed a 45,000-fold decrease in viral infections compared to untreated colonies.
