This fascinating fungus has been revered in Asian societies for thousands of years and is one of the oldest symbols of well-being and longevity. The reishi mushroom has a rather bitter, woody taste which is why it is traditionally prepared in a tea or as an extract or blended into smoothies and the like. Medicinal uses include: increased longevity, anti-cancer, liver regeneration, neuroprotective properties, immune enhancement, improved mood and to relieve depression.
