Pine tar along with many other ingredients due to a lack of proof of their effectiveness. Some pine tar products contain creosote, a probable carcinogen. Creosote potentially may be produced when the pine wood is heated up to high temperatures in the creation of pine tar. Pine tar is also used in veterinary medicine as an expectorant and an antiseptic in chronic skin conditions. Pine tar Pine tar is a sticky material produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation).

Coal gas flame but the light output could be greatly increased by using a gas mantle. The by-products of coal gas manufacture included coke, coal tar, sulfur and ammonia and these were all useful products. Dyes, medicines such as sulfa drugs, saccharine, and dozens of organic compounds are made from coal tar. Coke is used as a smokeless fuel and for the manufacture of water gas and producer gas. Coal tar was subjected to fractional distillation to recover various products, including Used in the manufacture of sulfuric acid Used in the manufacture of fertilisers Coal gas was initially manufactured by independent companies
