healing with turpentine
"Turpentine (also called spirit of turpentine, oil of turpentine, wood turpentine and colloquially turps[1]) is a fluid obtained by the distillation of resin obtained from live trees, mainly pines. It is mainly used as a solvent and as a source of materials for organic synthesis.
Turpentine is composed of terpenes, mainly the monoterpenes alpha-pinene and beta-pinene with lesser amounts of carene, camphene, dipentene, and terpinolene.[2]
The word turpentine derives (via French and Latin) from the Greek word τερεβινθίνη terebinthine, the name of a species of tree, the terebinth tree.[3] Mineral turpentine or other petroleum distillates are used to replace turpentine, but they are very different chemically.[4]"

certainly the modern petroleum distillates are likely poison... but the old version, from tree resin... i guess it depends.
