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.
Turpentine and its related products have a long history of medicinal use primarily as topical counterirritants for the treatment of rheumatic disorders and muscle pain. A gum derived from turpentine was used in traditional Chinese medicine to relieve the pain of toothaches. Other extracts (including the semi-synthetic derivative terpin hydrate) have been used for the treatment of cough and cold symptoms; 5 the cis-form of terpin hydrate is used as an expectorant.
