Comfrey Leaves, Comfrey Roots
Comfrey - Research
Comfrey extract has been studied for its ability to reduce pain and swelling in minor sprains when applied topically.6
The future of comfrey is under much debate. Because it contains chemicals that can cause liver damage and tumors when used internally, efforts are underway to develop a comfrey that is free of those chemicals.7
Traditionally the powdered root of comfrey has been applied topically to wounds, insect bites, bruises, sores; and to help stop bleeding.2 It has been used in baths to soften the skin2 and as an astringent.5 The root of comfrey was used in the past to treat bronchitis, cough, excessive menstrual flow, and diarrhea. A mouthwash or gargle made from the root of comfrey has been used for bleeding gums, throat inflammation, and hoarseness.2
The root, leaves, and extracts of comfrey can be found in various cosmetics such as hair products, lotions, creams, ointments and eyedrops.2
