For modern refining of turpentine, there are basically two ways of doing it: 1) gum spirits of turpentine is distilled from the bark resin only, and 2) wood turpentine is made from ground or chipped pine wood treated with a petroleum-based solvent called naphtha. The naptha draws out the resin from the wood.
Both frankincense and myrrh are derived from the gummy sap that oozes out of the Boswellia and Commiphora trees, respectively, when their bark is cut. The leaking resin is allowed to harden and scraped off the trunk in tear-shaped droplets; it may then be used in its dried form or steamed to yield essential oils.
