Polyporus umbellatus

Polyporus umbellatus is a medicinal mushroom in the family Polyporaceae of class Basidiomycetes. Polyporus umbellatus is commonly referred to as Grifola umbellata and more infrequently as Dendropolyporus umbellatus. Its common names include Zhu Ling (Hog Tuber) in Chinese, Chorei-Maitake (wild boar dung Maitake) or Tsuchi-maitake (Earth Maitake) in Japanese, Eichhase in German, polypore en ombelle in French, and umbrella polypore in English. Polyporus umbellatus is one of the commonly used and valued medicinal fungi, with sclerotia having been widely used for many years as an antidiuretic agent as well as an antidote in east Asian countries, most notably China, Korea, and Japan. Over the past few decades, researchers have found this taxon to contain numerous bioactive compounds shown to be responsible for antitumor, anticancer, antioxidant, nephroprotective, free radical scavenging, immune system enhancement, and antimicrobial activities. It was also reported that sclerotia of P. umbellatus had potent effects, suppressing the cytotoxic activity of leukemia and hepatitis.
