The Polyporus umbellatus grows wildly in Germany. It is not a very popular mushroom but has been known and valued in Asia for centuries.

The valuable ingredients that have been identified in the polyporus are acetosyringone and 3,4  Dihydroxybenzaldehyde. These play an important role in hair growth, however it is not yet clear as to how.

Additionally, they contain small quantities of calcium, potassium, iron, and only a small amount of sodium. Trace elements such as zinc, copper and manganese are also found in the mushrooms.
