What type of lotion is Salicylic acid and coal tar lotion?

Salicylic acid and coal tar lotion is generally used to treat scaly conditions of the scalp, including psoriasis and seborrhoeic dermatitis. Moderate to severe conditions respond better to other medications that are prescribed for application on the affected areas. Salicylic acid helps in softening the scales which aids in their removal. Coal tar is the result of destructive distillation of bituminous coal. It is a black and viscous substance that has a characteristic odour. Some users may find this odour unpleasant, enough to stop using the lotion. In the form in which it is applied, coal tar is diluted in solvents. Before the advent of corticosteroids, tars were prized as valuable drugs. Coal tar helps in suppressing itching of the diseased skin. In nature, salicylic acid is found in willow bark. It has been in therapeutic use for over a hundred years. Salicylic acid has multiple properties that make it useful in skin therapy. It is a keratolytic, i.e. helps in peeling rough, calloused skin. It has anti-inflammatory, antifungal and antimbacterial actions; it also helps other substances penetrate the skin (eg. corticosteroids). posted by Kumar.
