Note(s)This section has been translated automatically.
The therapeutic significance of tar products in dermatology is increasingly disappearing due to their toxicological component. Obsolete are the large-scale applications of tar products for inflammatory skin diseases (e.g. at the atopical eczema) which were common in former decades. Oil shale products extracted from natural sources still play an important role (e.g. in seborrhoeic eczema).
