Pain balms generally contain 3 components i.e methyl salicylate,menthol and camphor. When balm applied, salicylate absorbed through the skin and acts as an analgesic, menthol dilates the blood vessels. Because of the increased blood flow one gets a cool sensation in the balm applied area. This is useful in case of headache and rheumatic pains. Camphor also acts as rubefacient and mild analgesic.
