Creosote is a wood preservative made by distilling wood or coal tar at very high temperatures. It is commonly used to protect telephone poles, fence posts, and other wood that is exposed to the elements. Historically, it's also been used in tinctures and home remedies for different ailments, although the usage is largely discouraged today. There are a few long-term health applications associated with creosote as well.

Wood creosote is a greasy liquid that has a clear to yellow tint. It usually has a burned taste and flavor that is not considered to be appealing, but it was used for a number of years as an effective laxative, as well as treatment for coughs associated with a cold. This type has also been used as a disinfecting agent. It may also be found in liquid smoke meat flavoring.

Coal tar creosote tends to have different properties. It's amber to black in hue and is quite thick. This form was sometimes used in the treatment of psoriasis. More commonly, it has been used in animal dips, various types of insecticides, and repellants for animals and birds around camp sites. It is most often used as a wood preservative, however.
