Trametes versicolor, more commonly known as turkey tail, is a Polyporaceae family fungus growing worldwide on dead hardwood in temperate climates of North America, Europe, and Asia, producing thin, multicolored, leathery fruiting bodies with an earthy aroma. It has been studied for immunomodulatory, anti-inflammatory, & anticancer properties, largely attributed to its polysaccharide-rich constituents including protein-bound polysaccharide K (PSK) and polysaccharopeptide (PSP), as well as beta-glucans that stimulate immune responses. Clinically, turkey tail extracts have been investigated for adjunctive therapy use in cancers, particularly gastrointestinal cancers, with research indicating that PSK and PSP may support immune function and improve survival outcomes when combined with more conventional treatments. A recent review of polysaccharides from turkey tail found that these compounds exert direct cytotoxic effects on cancer cells in vitro, modulate immune cell activity, and show promising efficacy at the in vitro, in vivo, & clinical levels, supporting their investigation as adjuvants in cancer therapy PMID: 32466253. Historically, in Asian medicine, turkey tail  has been revered for promoting vitality and resilience. And its concentric, feather-like bands have made it a symbol of longevity & regeneration.
