Looking for a topical preparation? Try our ointments. All Be Gone ointments are in a base containing equal parts of lanolin and petrolatum. The petrolatum used in our base is pharmaceutical (USP) grade, which means it goes through a purification process to remove impurities. Petrolatum is traditionally used in homeopathic topical applications because it creates a seal allowing the active homeopathic ingredients to be absorbed by the skin.
