Comfrey

Comfrey is used for bruises, sprains, and dislocations. Applied in ointment form, Comfrey is considered an effective treatment for blunt injuries. The root portion of Comfrey is also used as a mouthwash and gargle for sore throat and gum disease. Taken internally, the root has also been used as a remedy for stomachache, ulcers, rheumatism, chest congestion, diarrhea, and inflammation in the lining of the lungs; but its effectiveness for these problems is unconfirmed and internal use is not recommended due to the presence of dangerous, cancer-causing compounds.

Do not use preparations containing Comfrey root. Ointments containing Comfrey leaf are considered safe when applied to unbroken skin for limited periods of time. Limit use of leaf-based Comfrey ointments to no more than 4 weeks. No drug interactions have been reported.
