Phellinus linteus (Japanese "meshimakobu", Chinese "song gen", Korean "sanghwang", English "Meshima") is a medicinal mushroom used in Japan, Korea and China for centuries to prevent ailments as diverse as gastroenteric dysfunction, diarrhea, haemorrhage and cancers. It is shaped like a hoof, has a bitter taste, and in the wild grows on mulberry trees. The stem's color ranges from dark brown to black. In Korean traditional medicine, the mushroom is consumed in the form of hot tea.
A paper published by Harvard Medical School reported that Phellinus linteus is a promising anti-cancer agent, but that more research is required to understand the mechanisms behind its anti-cancer activity.
Nine compounds were isolated from the active ethylacetate fraction of the fruiting body and identified as protocatechuic acid, protocatechualdehyde, caffeic acid, ellagic acid, hispidin, davallialactone, hypholomine B, interfungins A and inoscavin A of which interfungins A is a potent inhibitor of protein glycation.
Extracts from fruit-bodies or mycelium of Phellinus linteus stimulate the hormonal and cell-mediated immune function; quench the inflammatory reactions caused by a variety of stimuli, and suppress tumor growth and metastasis.
