Auricularia auricula not only has nutritional function, but also has the functions of benefiting qi and strengthening body, nourishing kidney and stomach, promoting blood circulation, etc. It can resist blood coagulation, thrombosis, reduce blood fat, reduce blood viscosity, soften blood vessels, make blood flow smooth and reduce the occurrence of cardiovascular diseases. Auricularia auricula also has a strong adsorption effect, and regular consumption is conducive to the timely discharge of garbage generated in the body. Auricularia auricula also has a good dissolving function for gallstones and kidney calculi, because it contains plant alkaloids which can promote the secretion of various glands in the digestive tract and urinary tract. Plant alkaloids can cooperate with these secretions to catalyze stones, lubricate the intestines and excrete stones.

Auricularia auricula also contains plant gum beneficial to human body and a substance called "polysaccharide", which is a natural tonic. It works together with the rich cellulose in Auricularia auricula to promote gastrointestinal peristalsis and prevent constipation, which is beneficial to the timely removal and discharge of toxic and harmful substances in the stool, thus preventing cancer such as rectal cancer, promoting the excretion of intestinal fatty foods and reducing the absorption of fat in foods, thus preventing obesity and losing weight.

Auricularia auricula contains a component that inhibits platelet aggregation, and its anti-platelet aggregation effect is equivalent to that of low-dose aspirin, which can reduce blood viscosity and make blood flow smooth. The research results of Beijing Cardiopulmonary Center have confirmed that the daily consumption of auricularia auricula10 ~15g has obvious anti-platelet aggregation, anticoagulation and cholesterol lowering effects. Eating auricularia auricula regularly for middle-aged and elderly people with high blood viscosity and high blood cholesterol can prevent cerebral thrombosis and myocardial infarction, which is beneficial to the prevention and treatment of hyperlipidemia, arteriosclerosis and coronary heart disease.

The study also found that lipid peroxidation is closely related to aging, and auricularia auricula also has the effect of anti-lipid peroxidation, which makes people live longer.
