Comfrey is a perennial herb related to forget-me-not and borage. Also known as Bruisewort and Knitbone, comfrey has earned an entry in every Materia Medica written since the 15th century, although it's been in use for much longer.

​Due to the presence of pyrrolizidine alkaloids, comfrey leaf is limited to topical uses today but should not be applied to open wounds. 

​Comfrey, also called boneset, bruisewort and radix consolidate, is a flowering perennial original to Eurasia and now distributed throughout temperate zones in North America. Although the plant is considered an invasive weed by some, it is also grown as an ornamental due to its drooping, bell-shaped flowers that range in color from yellow to red or violet.

​In Japan, comfrey has been cultivated as a vegetable for more than 2,000 years. The plant also has a long history of use in Asia and Europe as a topical anti-inflammatory agent, usually prepared as a poultice. However, because the leaf and root contain several hepatotoxic pyrrolizidine alkaloids, the internal use of this herb is limited to homeopathic formulations.












​Background: Comfrey has been used to treat respiratory problems of pleurisy
and bronchial inflammation. It was also once used to treat digestive problems
​such as irritable bowel syndrome and stomach ulcers. For thousands of years
​it has also been used to promote healing of injuries.

Research shows that some Comfrey Leaf and Root components are useful
in cell repair and have anti-inflammatory effects.

While the comfrey plant has its roots in Europe, it grows in many areas of
the world. North America, Australia, and Asia are all places where comfrey is found. It thrives in moist places.











Applications:
Anti-inflammatory/cell-proliferantComfrey is used to aid in healing and
reduce inflammation of injuries and infections.

Healing:
Comfrey root is used to promote healing of injuries such as broken bones,
sprains, bruises, and strains.
Skin:

Comfrey, in oil or ointment form, is useful in treating skin conditions. Acne, psoriasis, and boils are all improved by comfrey. It also reduces scar tissue during healing.

Description:
​Comfrey is a perennial plant that grows up to three feet high. It has bell-shaped flowers that are pink or white. The root and aerial parts are all rich in anti-inflammatory chemicals. The leave and flowers are harvested in the summer and the roots are harvested in the fall.

Comfrey Leaf and Root Dosage:
​Comfrey compresses can be placed on injuries to reduce the severity of the problem and speed up healing. Infused oil or ointment can be used for this purpose.Tincture of the root can be applied to acne to reduce spots.

Safety:
Comfrey root should not be used on dirty wounds because it can trap dirt. Make sure to apply to clean areas only. It should not be taken internally unless supervised by a health professional.

​Comfrey root is very high in nitrogen and potassium, two nutrients that plants require to grow and produce flowers, fruits and seeds.

Powdered comfrey root offers a convenient way to side dress plants directly or to enhance potting soil.Comfrey is one of 35 species of hairy-leafed, flowering plants in the Boraginaceae family, which includes many well-known relatives such as fiddlenecks, heliotrope, forget-me-nots and borage. Although comfrey itself is an attractive plant that produces colorful bell-shaped flowers, some gardeners would argue that its persistence to either invade or escape uncontained settings would constitute a weed.

​For centuries, comfrey leaf has been regarded as a vegetable in Asia and the root as a tonic in central and western Europe. While it was once common to produce teas and tinctures from the herb, the use or sale of comfrey products for internal use are now restricted in the US, Canada and Germany due to a high concentration of multiple pyrrolizidine alkaloids. Other compounds in comfrey, however, such as rosmarinic acid and allantoin, make the herb suitable for topical applications to counter inflammation and minor skin irritations.
