This is Dr. Christopher’s original BF&C formula, made with white oak bark, comfrey root, marshmallow root, mullein leaf, black walnut leaf, gravel root, wormwood, lobelia and skullcap. It’s the classic blend herbalists have used for generations in fomentations and poultices over areas that need extra care, like sore joints, strained muscles, bumps and bruises. How to use it: to make a fomentation, steep the herbs in hot water, soak a cloth in the warm tea and wrap it over the area. For a poultice, mix the powder with a little water or oil into a paste, apply it to the skin, and cover it with a cloth. Traditionally it’s left on overnight. Cautions: for external use only, because it contains comfrey. Do not take internally. Do not apply to broken skin or open wounds. Do not use if pregnant or nursing. Sold by the ounce.
