Turkey Tail (Trametes versicolor): The Definitive Species Guide
Among medicinal fungi, Trametes versicolor (Turkey Tail) is singular in having undergone clinical investigation in Japan, where studies have concentrated on its two principal polysaccharide-peptide fractions—PSK and PSP—and their capacity to modulate immune responses.
Polysaccharide-K (PSK): The Clinically Recognized Active Compound in Turkey Tail Mushroom
Polysaccharide K (PSK) has been the most extensively studied polysaccharide in Japanese oncology support research since the 1980s.
A Comparative Overview of Lentinan, PSK, and Beta-Glucan
Although both lentinan and PSK belong to the beta-glucan family, they operate through entirely distinct mechanisms of action.
Mushroom Polysaccharides in Cancer Research: Lentinan, PSK, and the D-Fraction
PSK is a polysaccharide complex that has been investigated for decades in Japan as part of oncology supportive care research.
Pachyman: The Defining Beta-Glucan of Poria cocos
Pachyman is a water-insoluble β‑glucan polysaccharide found in the sclerotium of the basidiomycete fungus *Poria cocos*. Its molecular architecture, the chemical transformations yielding bioactive derivatives, and the body of in vitro pharmacological evidence have been comprehensively surveyed.
