Dandelion is a perennial herb of Compositae, which can be used as medicine and food.

According to "Compendium of Materia Medica", it has the functions of clearing away heat and toxic materials, reducing swelling and dispersing stagnation, and promoting lactation, which is very effective in treating mastitis. Whether decoction is taken orally or mashed externally, it is effective. In addition, dandelion also has diuretic, laxative, jaundice-relieving, cholagogic and other effects, and is widely used in clinic. There is a saying in Compendium of Materia Medica: "Dandelion tender seedlings are edible, and eating them raw is particularly good for treating infectious diseases."

Shen Nong's Classic of Materia Medica, Tang Materia Medica, Dictionary of Traditional Chinese Medicine and other medical monographs of past dynasties all gave high praise.
