I have to admit, when I first learned about comfrey, it scared me. Herbs are complex and require studying before using.  Comfrey was also called “knitbone"  because it was used to heal bone fractures and wounds.  Something that could heal a bone fracture made me very cautious and nervous to add to my products.  I needed to get hands on and experiment with this plant.  Even though Comfrey should not be ingested; when used topically, the anti-inflammatory and emollient/demulcent action can help soothe pain, redness, swelling, bruising, and other signs of inflammation of the skin and musculoskeletal system.  This is why this plant is an important component in my Muscle/Joint Pain Salve.  Combined with St. John's Wort and Tulip Poplar, these plants provide a powerhouse of healing and pain relief.
