In 1985, Procter & Gamble acquired the Vicks Chemical Company. Vicks VapoRub contains camphor, eucalyptus oil, menthol, cedarleaf oil, nutmeg oil, special petrolatum, thymol, and turpentine oil. People working in a morgue often smear Vicks VapoRub above their upper lip to mask the odor of a decomposing corpse.
