Pinus palustris and other Pinus species
FAMILY: Pinaceae
SYNONYMS: Terebinth, therebentine, gum thus, gum turpentine, turpentine balsam, spirit of turpentine (oil).
GENERAL DESCRIPTION: ‘Gum turpentine’ is a term loosely applied to the natural oleoresin formed as a physiological product in the trunks of various Pinus, Picea and Abies species. Turpentine refers both to the crude oleoresin (a mixture of oil and resin) and to the distilled and rectified essential oils.
DISTRIBUTION: All over the world. The largest producer is the USA, also Mexico, France, Portugal, Spain, Greece, Scandinavia, New Zealand, Tasmania, India, China, the USSR, etc.
OTHER SPECIES: Apart from the longleaf pine (Pinus palustris), which is the leading source of American gum turpentine, other sources in the USA include the slash pine (P. elliottii) and the Mexican white pine (P. ayacahuite). In India the chir pine (P. roxburghii); in Tasmania the lodgepole pine (P. contorta var. latifolia); in China the masson or Southern red pine (P. massoniana); in Europe and Scandinavia the Scotch pine (P. sylvestris) and the sea pine (P. pinaster), as well as many others. See Botanical Classification section.
HERBAL/FOLK TRADITION: Known to Galen and Hippocrates for its many applications, especially with regard to pulmonary and genito-urinary infections, digestive complaints and externally as a treatment for rheumatic or neuralgic pain and skin conditions. In China the oleoresin has been used (both internally and externally) for centuries for excess phlegm, bronchitis, rheumatism, stiff joints, toothache, boils, sores, ringworm and dermatitis.
The turpentine essence or spirit of turpentine is said to be four times more active than the crude turpentine.
ACTIONS: Analgesic, antimicrobial, antirheumatic, antiseptic, antispasmodic, balsamic, diuretic, cicatrisant, counter-irritant, expectorant, haemostatic, parasiticide, rubefacient, stimulant, tonic, vermifuge.
EXTRACTION: Essential oil by steam (or water) distillation from the crude oleoresin, then rectified. ‘It has to be purified because it is viscous, coloured and acidic.’.
CHARACTERISTICS: A colourless, water white mobile liquid with a fresh, warm balsamic, familiar odour.
PRINCIPAL CONSTITUENTS: Mainly alphapinene (approx. 50 per cent), betapinene (25–35 per cent) and carene (20–60 per cent) in the American oils. In European oils the alpha pinene can constitute up to 95 per cent – constituents vary according to source.
SAFETY DATA: Environmental hazard – marine pollutant. Relatively non-toxic and non-irritant; possible sensitization in some individuals. Avoid therapeutic use or employ in moderation only.
AROMATHERAPY/HOME: USE Use with care for:
Skin care: Boils, cuts, fleas, insect repellent, lice, ringworm, scabies, wounds.
Circulation muscles and joints: Arthritis, gout, muscular aches and pains, rheumatism, sciatica.

Genito-urinary system: Cystitis, leucorrhoea, urethritis.
Immune system: Colds.
Nervous system: Neuralgia.
OTHER USES: Used in many ointments and lotions for aches and pains; and in cough and cold remedies. Neither oil nor oleoresin is used in perfumery work, although resin derivatives are used as fixative agents and in pine and industrial perfumes. Mainly known as a paint and stain remover, solvent and insecticide. Also used as a starting material for the production of terpineol, etc.... turpentine
