The Greeks used Comfrey (Symphytum officinale) as a healing herb since 400 BC as it was said to promote body tissue repair. They used it to stop heavy bleeding and treat bronchial problems. Dioscorides, a Greek physician of the 1st century, prescribed the plant to heal wounds and mend broken bones. Comfrey contains allantoin, a cell proliferator that stimulates new cell growth and increases cell production and thus supports more rapid healing. Comfrey has been used successfully on all parts of the body that have been injured. Comfrey (called the “knitter and healer”) stops hemorrhaging and bleeding and is particularly useful in treating blood in the urine. It aids in soothing inflammation and when used as a poultice can be applied to sore breasts, burns, wounds, swelling, and bites. It helps promote the secretion of pepsin, useful as a digestive aid.
