Coal Tar

Coal tar is a thick, dark liquid produced from the carbonization of coal, a process that heats coal in the absence of air. It contains a complex mixture of substances, including aromatic hydrocarbons, which have various industrial and medical uses. Coal tar is primarily known for its applications in paving, roofing, and the production of chemicals. It's also used in dermatology to treat skin conditions like psoriasis and eczema due to its anti-inflammatory and anti-fungal properties. However, some components of coal tar can be harmful, necessitating careful handling and regulation.
