According to the Yuan Dynasty's Daily Vegetation, Lentinus edodes has the functions of benefiting qi, nourishing muscles, treating wind and breaking blood. Huang Fuji's "Materia Medica Seeking Truth" in the Qing Dynasty also recorded that "Lentinus edodes is sweet in taste and flat in nature, which can benefit qi and contribute to urinary incontinence". In China, mushrooms are also used to treat acne, measles, detoxification bacteria poisoning, headache and dizziness, prevent colds and lower blood pressure, and prevent various mucosal ulcers, skin inflammation, weakness, scurvy, rickets, cirrhosis and various cancers.

Therefore, mushrooms have become health food for patients with hypertension.

Mushrooms are an excellent food raw material. There are many ways to eat mushrooms in China: fried pork slices with mushrooms, stewed chicken with mushrooms, drunk ribs with mushrooms, braised yellow croaker with mushrooms, steamed lean meat with mushrooms, etc. Especially mushroom soup, with unique flavor, refreshing and clearing the stomach.

Lentinus edodes is an edible fungus that grows on rotten wood. Pick it up and dry it with slow fire. It's a semi-finished product. However, it is inevitable that it will not be polluted during collection and drying. Therefore, before cooking, it is advisable to cut off the mushroom stalks and impurities, and then soak them in water to make the fruiting bodies scattered and easy to wash. After cleaning, soak in clear water for more than 4 hours to expand the fruiting body. When cooking, the clear water soaked in mushrooms can be used to make vegetable soup.
