Latin Name: Symphytum officinale
Common Names: Boneset, Bruisewort, Knitbone, Slippery Root
History: Native to Europe and parts of Asia, comfrey has a long history (at least 2000 years) in healing. It has been used to treat coughs and lung ailments, stop excessive bleeding, treat stomach problems, and to ease joint pain and inflammation. Its most common use, however, has been to heal wounds, bruises, and broken bones; in fact, almost every name (in all languages) for comfrey refer to knitting or mending bones or healing cuts and contusions. “Comfrey” comes from a Latin word meaning “to grow together,” and the botanical name “Symphytum” comes from the Greek, meaning plant that knits bones together. It was once also used as food for both people and animals.
Caution: Comfrey has been found to be toxic to the liver when taken internally in large amounts. It’s generally safe to use externally, but is best avoided by pregnant and nursing women, infants, and by people with liver, kidney, or vascular disease. It’s also toxic to animals, so be sure not to let them eat it.
Victorian Language of Flowers Meaning: Home sweet home
Cultivation: Perennial in zones 4 to 9. Easy to grow from seed, comfrey prefers full to part sun and rich, well-drained soil. It’s quite adaptable and can survive less-than-ideal conditions, including drought. Sow early indoors or outside as soon as soil can be worked. Sow just below surface of soil and tamp down–keep seeds moist (not wet). Sow seeds or seedlings with 2 feet (60 cm) of space around them as the plants get fairly large. Once plants are established in a spot they can live for decades and be difficult to remove, so take care when selecting a site. Comfrey is generally non-invasive, although it can self sow.
Uses: Comfrey is still used externally to treat inflammation, joint pain, and closed wounds and bruises. You can crush fresh leaves to make a poultice, apply fresh leaves to the affected area, use a salve, or apply oil that has had comfrey steeped in it. Treat poison ivy blisters by rubbing a fresh leaf on them. You can also use the chopped roots to make salves, ointments, and oils (or use a combination of leaves and roots). Leaves are best used before the plant blooms; roots are best harvested in late autumn or early winter.
In the garden, nitrogen- and potassium-rich comfrey leaves are used as fertilizer, in compost, and as mulch. Avoid using stems as they can take root and spread the plant where you don’t want it. You can also make a compost tea with the chopped leaves by steeping them in water for several weeks and then straining and diluting the resulting dark liquid 12:1 before applying to the garden.
Mara’s Uses: She makes a poultice of comfrey leaves to help speed up healing of a particularly bad injury. Comfrey would be one of the herbs used to make salves and oils for her apothecary business.
