Creosote is a dark, oily liquid that is produced by the distillation of coal tar or the wood of certain trees, particularly from the genus *Cryptomeria*. It is primarily used as a preservative to protect wood from decay and insect damage. In addition to its use in wood treatment, creosote has applications in various industrial processes and has historically been used in medicinal formulations. However, it is also known to be toxic and potentially carcinogenic.
