Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Thuja, particularly Thuja occidentalis (also known as white cedar or arborvitae), has a long-standing history in traditional medicine systems, especially in homeopathy and certain herbal practices. Traditionally, Thuja has been used to address a variety of skin conditions, including warts and other growths, and in some cases has been applied as a remedy for psoriasis. The rationale for its use in psoriasis is mainly anecdotal, based on centuries-old herbal and homeopathic traditions rather than robust clinical evidence.

In homeopathy, Thuja is considered for skin eruptions and is believed to help with scaling and thickening of the skin, which are characteristics of psoriasis. However, scientific studies examining the efficacy of Thuja—whether as a topical preparation or as a homeopathic dilution—for psoriasis are almost nonexistent. There are rare references in herbal medicine literature to its use for chronic skin diseases, but these are not substantiated with controlled trials or modern clinical studies. Any positive effects reported are based on individual case reports or traditional knowledge, not on systematic research.

Therefore, while Thuja continues to be used in some traditional and alternative medicine circles for psoriasis, there is little to no scientific validation for its effectiveness, and its safety profile for this use has not been rigorously studied.
