Pleurotus species are predominantly found in tropical forests and often grow on fallen branches, dead and decaying tree stumps, and wet logs  .
Many scientists have conducted extensive study on the nutritional and therapeutic properties of Oyster Mushroom as it is well known for possessing three required properties from food which are nutrients, biological properties and taste. The existence of bioactive molecules, which have been identified from oyster mushroom fruiting bodies, is responsible for the health-promoting and medicinal actions  . The known bioactive compounds are β-Glucans, peptides and proteins, terpenes, fatty acid esters and polyphenols. Because of the presented bioactive substances, Oyster mushrooms demonstrate some important therapeutic activity including, reduce blood sugar, fights inflammations, enhance immunity system, protects liver, lowers blood pressure, prevents strokes and reduces risks of heart attacks. When compared to vegetables, Oyster mushrooms have a larger protein content, minerals such as sodium, calcium, iron, phosphorus, and potassium, and Vitamin C and B complex were also observed.
