In general, there is no real distinction between CBD salve, CBD balm, or CBD ointment. One can use these terms interchangeably!
According to the Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health, an ointment is defined as: “a semisolid preparation for external application to the skin or mucous membranes… [that] consists of medicinal substances incorporated in suitable vehicles.”
So, a CBD balm or salve is in essence a medicine-infused mixture that is applied directly to the skin.
CBD salves and balms differ from CBD creams and lotions in that they contain no water. Salves and balms use only fatty oils and waxes. Because cannabidiol (CBD) is hydrophobic in nature, the more fatty acids a balm contains, the more CBD it can carry.
