Bái Hè Jūn is a traditional Chinese medicinal herb. It is the fruiting body of Trametes orientalis (Yasuda) Imaz. [also known as Polystictus orientalis Yasuda], a fungus belonging to the family Polyporaceae. The fruiting body is corky and woody, sessile or semi-applied to applied and reflexed, often overlapping like roof tiles. The pileus is semicircular, nearly shell-shaped or nearly rounded, 4–20 cm in long diameter, 3–12 cm in short diameter, and 3–10 mm in thickness. The surface is yellowish, reddish-brown or greyish-brown, with fine hairs that later fall off to become smooth, often with concentric rings ranging from light brown to dark greyish-brown. The pore surface is nearly white to pale yellow or pale rusty; the pores are round. It has a faint odor and a bland taste. It grows on rotting wood of broad-leaved trees.

Modern Pharmacology
Currently, specific modern pharmacological research on Bái Hè Jūn is relatively limited. Its medicinal value is primarily based on traditional Chinese medical theory and clinical experience. As the fruiting body of a polyporaceous fungus, Bái Hè Jūn is taxonomically related to other medicinal fungi such as Poria (Fú Líng) and Polyporus (Zhū Líng), and may contain similar active components including polysaccharides and sterols. However, its specific pharmacological mechanisms require further investigation.
