Have rubefacients been shown the red light?
Have you got a cupboard full of those creams that you rub on to soothe sore muscles and they make your skin red and hot? That must work, mustn’t it? Well a Cochrane review has just been updated with the latest evidence on these topical ‘rubefacients’; the lotion or potion contains a drug (in this review they all contained salicylates, a commonly used rubefacient) which increases the blood flow, hence the reddening effect. They were used for acute painful conditions, sprains, and chronic ones, like osteoarthritis.
Bottom line? There’s no good evidence that they give useful pain relief. You can read more by visiting the link below.
