Auricularia auricula(Black fungus) powders and extracts


Auricularia auricula-judae, known as the Jew's ear, wood ear, jelly ear or by a number of other common names, is a species of edible Auriculariales fungus found worldwide. The fruiting body is distinguished by its noticeably ear-like shape and brown colouration, it grows upon wood, especially elder.Today, the fungus is a popular ingredient in many Chinese dishes, such as hot and sour soup, and also used in Chinese medicine. In the West, A. auricula-judae was used in folk medicine as recently as the 19th century for complaints including sore throats, sore eyes and jaundice, and as an astringent. It is also used in Ghana, as a blood tonic. It has been found that A. auricula-judae contains various bio-compounds that have anti-tumpr, antiviral, antibacterial, anti parasitic, hypoglycemic, anticoagulant and cholesterol-lowering properties. Auricularia auricula-judae has been the subject of research into possible medicinal applications. Experiments in the 1980s concluded that two glucans isolated from the species showed potent antitumour properties when used on mice artificially implanted with Sarcoma 180 tumours [1] . Another chemical extracted from the species was an acidic polysaccharide (made up of mostly mannose, glucose, glucuronic acid and xylose) which showed anticoagulant properties. The article concluded that "the polysaccharides from these mushrooms may constitute a new source of compounds with action on coagulation, platelet aggregation and, perhaps, on thrombosis" [2] .Further, research on genetically diabetic mice showed that a polysaccharide extracted from A. auricula-judae had a hypoglycemic effect; mice fed with food including the polysaccharide showed reduced plasma glucose, insulin, urinary glucose and food intake [3] .
