Radian-b pain relief spray pump action provides symptomatic relief of muscular aches and rheumatic pain including fibrosis, sciatica, lumbago, sprained ligaments, bruises, muscle stiffness, strains, tennis elbow and golf shoulder. This preparation contains three active ingredients menthol, camphor and salicylic acid. Menthol relieves itching and causes the blood vessels on the surface of the skin to widen. This causes a sensation of coldness followed by a reduction in pain. Camphor and methyl salicylate are counter-irritants, which when applied, cause redness and heat to be produced. When applied directly, this distracts the brain from the original pain and therefore reduces perception.
