Coal Tar Preparations
Crude coal tar extracts have been used to treat the inflammation and itch of eczema. Coal tar treatments have a soothing effect on inflamed skin. Tars contain hundreds of chemicals, most of which have never been identified, but seem to have a medicinal effect. However, most people shy away from these preparations because they tend to be messy, time consuming, smelly, and inconvenient.
Cautions:
Coal tar should not be used for acute dermatitis because it may cause stinging and irritation. As well, folliculitis (inflammation of the hair follicle) and sensitivity to light have been reported.
