Turkey Tail (Trametes versicolor) is a common polypore mushroom found worldwide, growing on dead hardwood. Its name derives from its colorful, fanned appearance, resembling a turkey's tail. For centuries, it has been utilized in traditional medicine, particularly in Asia, for its purported health-promoting properties. Modern scientific interest in Turkey Tail has focused on its complex carbohydrate compounds, specifically polysaccharides, such as polysaccharide K (PSK) and polysaccharopeptide (PSP), which are believed to be responsible for many of its biological activities. These extracts are commonly isolated and used in supplemental forms. While generally considered a dietary supplement, in some countries, like Japan, PSK derived from Turkey Tail has been approved as an adjuvant cancer therapy. The mushroom is typically consumed as an extract, tea, or in powdered form. Its role in supporting overall well-being and its specific effects are areas of ongoing research.
