Warming lubricant  Warming lubricant is a personal lubricant with the warming effect created due to added ingredients. The warming thermoception is achieved on the contact with skin or by natural body moisture. The main ingredient of the majority of warming lubricants is glycerol, a viscous sugar alcohol. Some of them include capsaicin, the active component of chili peppers. Other ingredients are: propylene glycol, alcohol, herbal extracts, and even some vitamins. Natural and artificial flavors are used for manufacturing flavored and edible warming lubricants. Warming lubricants can be water-based or honey-based. Water-based lubricants are applied for vaginal or anal intercourse or while playing with sex toys or for masturbation. The honey-based products are stickier and are usually applied for tummy play. Such lubricants are not intended or recommended for internal application. A small amount of the warming lubricant may be rubbed into nipples, ears, or other sensitive parts for erotic sensation. Warming lubricants are often used as a massaging aid for rubbing into muscles to warm them. Though warming lubricants contain no toxins, they may cause an allergic reaction. The content of glycerin or acacia honey may encourage the development of infections such as yeast infections.
