Boraginaceae > Symphytum officinale var. ,



Symphytum officinale is a perennial flowering plant of the genus Symphytum in the family Boraginaceae. Along with several other species of Symphytum, it is commonly known as comfrey.

The hardy plant can grow to a height of 60 cm.

Comfrey has been used in folk medicine as a poultice for treating burns and wounds. However, internal consumption, such as in the form of herbal tea, is discouraged, as it can cause serious liver damage.[1]
