Chelidonium majus subsp. grandiflorum, the greater celandine, is a species of flowering plant in the family Papaveraceae, native to Siberia, China, and Korea. Chelidonium majus was described by Carl Linnaeus in volume one of his Species Plantarum in 1753. The name celandine comes from Late Latin celidonia, from earlier Latin chelidonia or chelidonium, and ultimately from Ancient Greek chelidon meaning “swallow”, hence the common name swallowwort. Ancient writers said that the flower bloomed when the swallows returned and faded when they left. It is a traditional folk remedy against warts.
