Certain mushrooms, particularly tree-dwelling saprophytic mushrooms, contain significant quantities of terpenoids.
As with mushroom polysaccharides and glycoproteins it would appear that terpenoids and related triterpenes exhibit host-mediated anti-tumour activities.
Host-mediated Anti-tumour Activities
Terpenoids are also the most abundant group of anti-inflammatory molecules found in mushrooms.
Reishi (Ganoderma lucidum), for example, contains an impressive 140 variations of terpenoids and hence the reason is has been revered for thousands of years.
Terpenoids help reduce inflammation by reducing the production of pro-inflammatory mediators such as cytokines, TNF-α, IL-6, postaglandins and nitrous oxide.
