Fomitopsis officinalis: a Species of Arboreal Mushroom with Promising Biological and Medicinal Properties

Medicinal mushrooms of the order Polyporales have a long history of use, which is evidenced by the finding of dissected fruiting bodies with Ötzi, who lived over 5000 years ago. Because of its valuable biological properties and its use in 18th and 19th‐century pharmacy, Fomitopsis officinalis used to be mass‐collected. Moreover, the large demand for larch wood and non‐wood materials (resin) caused an excessive exploitation of larch forests, which directly contributed to the disappearance of F. officinalis from its natural environment. The qualities of medicinal preparations obtained from the F. officinalis fruiting bodies are determined by the unique composition of its bioactive compounds, such as: triterpenoids, polysaccharides, organic acids, coumarins and phenolic compounds. It has been proved that both crude extracts and the compounds isolated from F. officinalis have a wide spectrum of therapeutic effects, including anti‐inflammatory, cytotoxic, and antimicrobial effects.
