This deep dark green, can’t see-through oil is made by several week dried comfrey leaf maceration in organic olive oil. The ratio of comfrey leaf to olive oil is 1:8. Comfrey has a great reputation as a topical skin aid and was used for a variety of ailments for many generations. Its Latin name is Symphytum officinale, and 'symphytum' actually means to join or unite. This is an excellent oil to use in massage, or in your own salve-making creations to further moisturize and strengthen the skin. This is not an essential oil but a whole leaf extraction.
