Comfrey is an amazing plant and has many medicinal gifts. It is known to help with sprains, bruising even bone breaks, it's kickname is 'boneset'. My homegrown comfrey is infused in extra virgin olive oil, beeswax is added and essential oils of peppermint, eucalyptus, black pepper, lavender and clove to help with warmth to the skin. Also good as a massage balm.
