Yuan(1998) demonstrated that Wood Ear’s water-soluble polysaccharide fraction has a hypoglycemic effect on genetically diabetic mice. A water insoluble glucan similar to β 1-3 D-glucans and β 1-6 D-glucans (560,000-610.00 bp) was isolated from the hot water extract of the fruiting bodies. In vitro tests have shown strong antitumor activity against the solid form of Sarcoma 180 Kio(1991).

In Chinese medicine, mushrooms are used in patients suffering from arteriosclerosis to improve the flow of blood and thus treat circulatory problems. They also have anti-inflammatory effects and lower cholesterol levels.
In commerce, Judas ears are usually available dried and are imported in large quantities, especially from Vietnam. They are rich in iron, potassium and magnesium and contain phosphorus, silicon and vitamin B1. In Chinese cuisine, fresh or rehydrated and freed from the stalk are used. When swelling, they reach many times their size in the dry state. They have only a slight, mushroom-like inherent flavor, but a special mouthfeel: a peculiar texture reminiscent of fresh seaweed. In addition, the Judas ear absorbs very well the flavors of the liquids in which it is prepared.
