Mustard Oil : A Medicinal Miracle
Mustard is a rubefacient which causes reddening and warming of the skin. Its plaster or paste made with water, is applied as analgesic in rheumatism, sciatica, paralysis of limbs and other muscular pains. The plaster should, however, never be directly applied to the skin as it may cause painful blistering. A layer of lint material should be put between the mustard paste and the skin.
