Naming
Phylogenetic analysis has begun to better differentiate between many closely related species of ''Ganoderma''; however, there is still disagreement as to which have the most medicinal properties. In addition, variations within the same species as well as the growth substrate and environmental conditions all the way through to preparation can have a substantial effect on the medicinal value of the product.
Uses
Like ''G. lucidum'', ''G. tsugae'' is non-poisonous but generally considered inedible, due to its solid woody nature; however, teas and extracts made from its fruiting bodies allow medicinal use of the compounds it contains. A hot water extraction or tea can be very effective for extracting the polysaccharides; however, an alcohol or alcohol/glycerin extraction method is more effective for the triterpenoids.Studies in mice has shown that ''G. tsugae'' shows several potential medicinal benefits including anti-tumor activity through some of the active polysaccharides found in ''G. tsugae''
''G. tsugae'' has also been shown to significantly promote wound healing in mice as well as significantly increase the proliferation and migration of fibroblast cells in culture.
