What is pine oil composed of?

Question

Also, how is it made...can you get oil from ground up needles and wood?

Answer 1

From Wikipedia:

"Chemically, pine oil consists mainly of cyclic terpene alcohols.[1] It may also contain terpene hydrocarbons, ethers, and esters. The exact composition depends on various factors such as the variety of pine it is produced from and the parts of the tree used."

and

"Pine oil is an essential oil obtained by the steam distillation of needles, twigs and cones from a variety of species of pine, particularly Pinus sylvestris."

So yes, you can get it out of ground up needles and wood.  Although grinding may not be necessary, it should facilitate the distillation process.
