According to Dr. Ngo Duc Phuong, Director of the Institute of Traditional Vietnamese Medicine, the Vietnamese dandelion, scientifically known as Lactuca indica, belongs to the daisy family (Asteraceae), and is different from the European dandelion (Taraxacum officinale). In Vietnam, Lactuca indica is a familiar plant, used as a vegetable and medicinal herb for treating heat-related ailments, liver and gallbladder problems, and digestive issues.

In traditional medicine, dandelion has a bitter-sweet taste and a cooling nature, with the effect of clearing heat. In addition, this plant is used to detoxify, cool the liver, support those with hepatitis, internal heat, acne, aid digestion, and reduce bloating. Notably, dandelion is also used in folk medicine for cases of mastitis and blocked milk ducts.

In daily life, the leaves and young shoots of the dandelion can be eaten as vegetables (boiled or used in soups), and the whole plant can be dried and brewed into a tea.
