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.
From what I've read, Edgar Cayce also used turpentine as part of his healing regimens. Also, apparently in the old days, some people gave their kids some drops of turpentine on sugar cubes as a de-wormer. Here is a thread on earthclinic talking about it....OTE OF CAUTION: From what I've read the ONLY acceptable Turpentine that can be used is  100% pure gum spirits of turpentine . Apparently any other turpentine/paint thinner is petroleum based and NOT to be used.
