Comfrey

The Basics
Comfrey, also called knitbone, is made primary from the leaves of this plant. It contains Vitamins A, C, and E along with allantoin and rosmarinic acid. Allantoin benefits wound healing and is found in the leaves and roots of the comfrey. Rosmarinic acid has anti-inflammatory properties.

More specifically, comfrey is used to treat the following: bedsores, stings, bruises, burns, dry skin, dermatitis, leg ulcers, rashes, and sunburn.

Sources
Comfrey is available in the following forms: ointments (5%- 20% comfrey), creams, and liniments. The leaves may be prepared as a poultice to relieve pain from sprains, pulled muscles, and broken bones.

Guidelines and Cautions
Comfrey should only be used externally. Always follow package directions. Pay strict attention to limited use guidelines on packaging.

Only use comfrey under the supervision of a medical professional.

Do not apply to broken skin.

Comfrey is very toxic to the liver. Preparations made from the comfrey root are 10 times more poisonous than those made from the leaves. Death from poisoning is possible.

Women who are pregnant or nursing should not use comfrey.

As with any vitamin, herb, or supplement, always consult a medical professional prior to incorporating these substances into your diet.
