Common comfrey

<em>Symphytum officinale</em>, commonly known as common comfrey, is a perennial herbaceous plant in the family Boraginaceae. It is native to Europe and parts of Asia and has been naturalized across North America, Oceania, and South America. Common comfrey typically grows in moist, nutrient-rich habitats including riverbanks, ditches, floodplain meadows, and woodland margins. The plant produces large, lance-shaped leaves covered in coarse hairs and bears drooping clusters of tubular flowers that range from pale purple to white. It has a long history of medicinal use, particularly for wound healing and bone repair, due to the presence of allantoin in its tissues. However, it also contains pyrrolizidine alkaloids that can be toxic in high doses. The species is assessed as Least Concern by the IUCN. Biological traits of this species remain poorly documented in the scientific literature.
