Abstract. Arctium lappa, commonly known as burdock, is being promoted/recommended as a healthy and nutritive food in Chinese societies. Burdock has been used therapeutically in Europe, North America and Asia for hundreds of years. The roots, seeds and leaves of burdock have been investigated in view of its popular uses in Traditional Chinese Medicine (TCM). In this review, the reported therapeutic effects of the active compounds present in the different botanical parts of burdock are summarized. In the root, the active ingredients have been found to "detoxify" blood in TCM term and promote blood circulation to the skin surface, improving the skin quality/texture and curing skin diseases like eczema. Antioxidants and anti-diabetic compounds have also been found in the root. In the seeds, some active compounds possess anti-inflammatory effects, and potent inhibitory effects on the growth of tumors such as the pancreatic carcinoma. In the leaf extract, the active compounds isolated can inhibit the growth of micro-organisms in the oral cavity. The medicinal uses of burdock in treating chronic diseases like cancers, diabetes and AIDS have been reported. However, it is also essential to be aware of the side-effects of burdock including contact dermatitis and other allergic/inflammatory responses that might be evoked by burdock.
