Pine Oil

Pine oil is an essential oil obtained by the steam distillation of stumps, needles, twigs and cones from a variety of species of pine, particularly Pinus sylvestris. As of 1995, synthetic pine oil was the "biggest single turpentine derivative. Synthetic pine oils accounted for 90% of sales as of 2000.

In alternative medicine, it is said to be used in aromatherapy, as a scent in bath oils or more commonly as a cleaning product, and as a lubricant in small and expensive clockwork instruments. It may also be used varyingly as a disinfectant, sanitizer, mircobicide / microbistat, virucide, insecticide, and a massage oil. It is also used as an effective organic herbicide where its action is to modify the waxy cuticle of plants, resulting in desiccation.
