Ichthammol BP, also known as ammonium bituminosulfonate, is a dark brown to black, viscous, sulfur-rich, semi-solid substance derived from the distillation of shale or bituminous rocks. It has a characteristic tar-like odor and is highly valued in pharmaceutical and dermatological applications for its anti-inflammatory, antiseptic, antipruritic (anti-itch), and keratolytic properties. Ichthammol penetrates deeply into the skin and soft tissues, helping to alleviate inflammation and promote healing. It is widely used in topical preparations for treating skin conditions such as eczema, psoriasis, boils, abscesses, and other dermatological infections.
