'''''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.<ref>http://journals.cambridge.org/download.php?file=%2FPHN%2FPHN7_07%2FS1368980004001156a.pdf&code=f5f837200b6f79862cf84720c13bb8d5</ref>
