Liniments are topical preparations meant for external application that are rubbed on the skin. They come in liquid or semi-liquid forms and contain substances dissolved or suspended in oils, alcohol, or emulsions. Liniments are used for their antipruritic, astringent, emollient, analgesic, rubefacient, and counterirritant properties. There are two main types - alcoholic liniments that penetrate the skin more readily and oleaginous liniments that are milder but better for massage. Examples given are Compound Calamine Liniment for dermatitis and eczema, and Efficascent Oil for temporary relief of minor muscle and joint aches and pains.
