WHAT IS Oyster mushroom USED FOR?

Inflammation is a protective response to tissue injury which usually subsides after healing occurs. Inflammation can be triggered by an innocuous agent or by an autoimmune process, as in rheumatoid arthritis. During the process of inflammation, proinflammatory cells (macrophages and monocytes) release proinflammatory mediators, such as tumour necrosis factor-α (TNF-α), cytokines (interleukin (IL)-1 and IL-2), prostaglandin E2, and nitric oxide (NO).

Increased expression and activity of cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) also play an important role in the inflammatory process. In such cases, the defense reactions may cause tissue injury where anti-inflammatory drugs may be needed to overcome the inflammatory process. Currently available anti-inflammatory drugs possess side effects which can cause problems during clinical use. Nonsteroidal anti-inflammatory drugs (NSAIDs) which are COX-2 inhibitors are known to cause serious gastrointestinal disturbances including bleeding, ulceration, and other effects such as hypersensitivity reactions. This has led to an increase in demand for natural products with anti-inflammatory activity with fewer side effects. Plants as well as mushrooms have been targeted in the search for new anti-inflammatory agents. Some plants and mushrooms have been screened and identified as sources to treat inflammation.

Pleurotus species which are commonly called “oyster mushrooms” belong to the Basidiomycetes fungi of the order Agaricales and family Pleurotaceae. They are characterized by a fruiting body with an eccentric stalk and a wide cap. Pleurotus ostreatus is an edible mushroom commonly known as American oyster.

Studies have reported various properties of P.o such as antinociceptive, hypocholesterolaemic, antioxidant [1]
