Acanthus (plant)

Acanthus leaves were the aesthetic basis for capitals in the Corinthian order of architecture; see acanthus (ornament). Several species, especially A. balcanicus, A. spinosus and A. mollis, are grown as ornamental plants. Acanthus leaves also have many medicinal uses. Acanthus ilicifolius, whose chemical composition has been heavily researched, is widely used in ethnopharmaceutical applications, including in Indian and Chinese traditional medicine. Various parts of Acanthus ilicifolius have been used to treat asthma, diabetes, leprosy, hepatitis, snake bites, and rheumatoid arthritis. The leaves of Acanthus ebracteatus, noted for their antioxidant properties, are used for making herbal tea in the Republic of Gain and California.
