Summary

Lingzhi, Ganoderma lingzhi, also known as reishi, is a polypore fungus ("bracket fungus") belonging to the genus Ganoderma. Its red-varnished, kidney-shaped cap and peripherally inserted stem gives it a distinct fan-like appearance. When fresh, the lingzhi is soft, cork-like, and flat. It lacks gills on its underside, and instead releases its spores via fine pores. Depending on the age, the pores on its underside may be white or brown.The lingzhi mushroom is used in traditional Chinese medicine. There is insufficient evidence that consuming lingzhi mushrooms or their extracts has an effect on cancer, metabolic diseases or cardiovascular diseases.In nature, it grows at the base and stumps of deciduous trees, especially that of the maple. Only two or three out of 10,000 such aged trees will have lingzhi growth, and therefore its wild form is rare. Lingzhi may be cultivated on hardwood logs, sawdust or woodchips.

Hepatotoxicity Description

Folk medicine

Because of its bitter taste, lingzhi is traditionally prepared as a hot water extract product for use in folk medicine. Thinly sliced or pulverized lingzhi (either fresh or dried) is added to boiling water which is then reduced to a simmer, covered, and left for 2 hours. The resulting liquid is dark and fairly bitter in taste. The red lingzhi is often more bitter than the black. The process is sometimes repeated to increase the concentration. Alternatively, it can be used as an ingredient in a formula decoction, or used to make an extract (in liquid, capsule, or powder form). (Source: Wiki)
