Extreme Comfort is a concentrated topical liniment containing comfrey and menthol. Comfrey, also known as “knitbone”, is a medicinal plant that has been used in traditional medicine for centuries to treat many types of injury. Extreme Comfort may help alleviate pain associated with minor joint and bone diseases as well as soft tissue and muscle injuries. It may also be used for bucked shins, strained tendons and suspensory ligaments, hot or swollen joints, stocked up lower limbs, sore backs, and strained or pulled muscles. It can be applied as a sweat, under bandages or unbandaged - the thick, concentrated formula will not easily run off once applied. Extreme Comfort is natural, safe and it does not test in competition.
