Monographs of essential oils that have caused contact allergy / allergic contact dermatitis
Published in Anton C. de Groot, Monographs in Contact Allergy, 2021
Thuja occidentalis L. is an evergreen coniferous tree which grows up to 25 meter tall and one meter in diameter. It is native to Canada and the USA and is cultivated in China, Korea, Russia (European part), and Europe, often for ornamental purposes (2,12). One of its common names is ‘Arborvitae’, which is particularly used in the horticultural trade in the United States and is Latin for ‘tree of life’ - due to the supposed medicinal properties of the sap, bark and twigs. In folk medicine, Thuja occidentalis has been used to treat various diseases (2). It has a myriad of applications in Western herbal medicine, traditional Chinese medicine, homeopathy and aromatherapy. The pharmaceutical, pharmacological and clinical properties of Thuja occidentalis (products) have been reviewed (3,4).

Aldhebiani et al. (2015) describe in the Saudi Journal of Biological Sciences something of the background regarding viral diseases of fig trees, most especially Ficus carica, the fig of commerce (Lansky et al. 2008, 2010). A sign of one of these diseases, Fig leaf mottle-associated virus-1 (FLMaV-1), is chlorosis (as in bleaching): the appearance of white spots, streaks, blots, rings, or feathery wisps throughout the leaf. These chlorotic areas can be measured and the severity of disease in leaves appearing 3 weeks after a graft graded. Extracts of four plants, Thuja leaf, ginger roots, harmal seeds, and turmeric rhizome (Curcuma longa), were investigated as possible inhibitors of FLMaV-1. Pretreatment for days prior to grafting of FLMaV-1 infected rootlets with either the Zingiber or the Curcuma provided protection against the development of viral symptoms in the leaves, and against infection-associated higher total photosynthesis pigments, total soluble intracellular proteins, and total phenolics. As protectors, harmal and Thuja leaf had no effect. But as potential treatments following the outbreak of leaf signs, the ginger and turmeric extracts were without effect, but the harmal and Thuja leaf extracts were effective as antiviral agents, resulting in significant reduction in the infection-associated parameters.

Thuja occidentalis extracts are antiviral against warts14, anti-inflammatory, antioxidative and affect cell-mediated immune responses and cytokine levels15–18. Similar to most herbal preparations, Thuja occidentalis extracts and Baptisia tinctoria extracts comprise multitudes of substances which contribute or may contribute to their multi-target immunomodulatory activities. The set of active contributors in Thuja occidentalis extracts mainly includes essential oils, flavonoids and polysaccharides19, and in Baptisia tinctoria extracts contain mainly arabinogalactans and arabinogalactan proteins20. Baptisia tinctoria extracts stimulate lymphocytes and elevate antibody production21,22.

As homeopathy aims at treating the individual person, not a certain disease or bacteria, medication was chosen individually. Consequently, not a single, but several different remedies were used. All remedies were used as liquids in high potencies (LM-potency).15 In the 16 men receiving homeopathic treatment, 6 different remedies were used (Staphysagria, Nux-vomica, Lycopodium clavatum, Hypericum, Sulphur and Acidum nitricum) with Staphysagria and Nux-vomica being the most frequently used medications. In the 9 female participants, more and different remedies were used (Causticum, Staphysagria, Medorrhinum, Nux-vomica, Sulphur, Sepia, Lycopodium clavatum Thuja, Silicea und Kalium- carbonicum), and the medication had to be changed more frequently within the course of the study.

Several other natural plant extracts have been reported to have similar positive effects on hair growth. For example, Geranium sibiricum L. (Geraniaceae) extract (Boisvert et al. 2017) and Miscanthus sinensis var. purpurascens Andersson (Gramineae) flower extract (Jeong et al. 2018) have exhibited propensity to not only induce the anagen phase but to maintain it. In addition, Zhang et al. (2013) observed that topical application of Thuja orientalis L. (Cupressaceae) extract in C57BL6/N mice induced an earlier anagen phase and prolonged the mature anagen phase, whereas the extract of Polygonum multiflorum Thunb. Polygonaceae has been demonstrated to increase the number and size of hair follicles in telogenic C57BL6/N mice (Park et al. 2011).
