Monographs of essential oils that have caused contact allergy / allergic contact dermatitis
Published in Anton C. de Groot, Monographs in Contact Allergy, 2021
One individual developed erythema multiforme-like contact dermatitis from the application of thuja essential oil on hemorrhoids. He reacted to thuja oil (pure and 1% in petrolatum), the fragrance mix, colophony, juniper tar and pine tar, which are, with the exception of the fragrance mix, all tree products (9).

At Yoshioka Skin Clinic, Yoshimi was prescribed pine tar ointment and low-potency topical steroids. Since she had been using such potent topical steroids before then, switching to a lower potency caused a sudden exacerbation of her symptoms. Her symptoms became so severe that she was not even able to stand, so she was forced to quit her job. At the time, while still wearing her pyjamas, she had her boyfriend help her into a taxi to her office, and her boss came out to the taxi so that she could take care of her resignation documents.

Leaves yield circa 0.3% of a balsam-scented oil compared to about 0.4% for longleaf pine. This leaf oil consists mostly of borneol, cadinene, camphene, and beta-pinene. The natural oleoresin exudate from the resin ducts contains circa 66% resin acids, 25% turpentine, 7% nonvolatiles, and 2% water. Turpentine from slash pine contains I-α-pinene, while that from longleaf contains some i/-pinene. Pinene is the main constituent of turpentine. Dipentene and other monocyclic terpenes constitute 5 to 8% of gum and refined sulfate turpentine, 15 to 20% of wood and crude sulfate turpentine. Camphene constitutes 4 to 8% of wood turpentine, and 0% of gum turpentine. Rosin consists mostly of diterpene resin acids of the abietic (abietic, neoabietic, palustric, and dehydroabietic) and pimaric types (pimaric, iso-pimaric, and sanaracopimaric). Pine tar contains turpentine, resin, guaiacol, creosol, meth-ylcreosol, phenol, phlorol, toluene, xylene, etc. Crude tall oil contains 40 to 60% resin acids, 40 to 55% fatty acids (mostly n-C18, 75% monoenoic, and 25% dienoic, with traces of trienolic and saturates), and 5 to 10% neutral properties.17

Eczema or atopic dermatitis (AD) is a common childhood skin disease associated with impaired quality of life (1,2). Baseline treatment includes regular emollient usage and the proactive usage of topical corticosteroid and immunomodulating agents during disease quiescence and flares (1–4). Pine tar is derived from pine and claimed to contain anti-inflammatory and antibacterial ingredients (5). Pine tar and other tar products had limited popularity in previous time due to uncertain carcinogenic properties; however, manufacture process, pine tar is purified to remove toxic and carcinogenic components in the modern manufacture process. It is suggested that the high polycyclic aromatic hydrocarbon (PAH) content of tars could be one of the active ingredients that contribute to anti-inflammatory effects and skin barrier repair in AD (5–7). In a pilot study, a proprietary bath oil containing pine tar was efficacious in reducing AD severity (8). It is noted that parents are very receptive to daily showering and bathing despite inconsistency with topical treatment. Hence, bathing could offer an alternative therapy for repairing the skin barrier, inflammation, and infections associated with AD. The null hypothesis of this randomized trial is that there is no difference in clinical efficacy between a pine tar product and its vehicle for childhood AD.
