Balsam turpentine is the oleo-gum-resin obtained by incisions made on the trunks of several trees belonging to the genus Pinus. The common American turpentine comes from P. palustris. Crude turpentine contains 75 to 90% resin and 10 to 25% oil. It is of paramount importance to use special techniques in making incisions, because the tree otherwise may die in a short time. A gum (gum turpentine) consisting of white incrustations is formed around the incisions in the tree. Rosin is the resinous residue of the distillation of turpentine. There are several varieties of rosin, varying in color from the palest amber to nearly black and from translucent to opaque, depending on the turpentine source. Colophony is the name of the common rosin variety. The part used is the oleo-gum-resin (turpentine balsam). Turpentine has a penetrating and characteristic odor and a pungent, bitter taste.

용도Turpentine is a mixture of substances called terpenes, primarily pinene. Gum turpentine is extracted from pine pitch; wood turpentine, from wood chips. It has had greater home than industrial use as a solvent. It is irritating and anesthetic and is one of the few solvents that causes allergic contact dermatitis. The incidence of sensitization varies with the type of pine, being generally higher with European than American pines. Owing to the frequency of allergic dermatitis, the availability of turpentine is now extremely limited. One recent study suggested that occupational paternal exposure to turpentine was associated with neuroblastoma in offspring.
