Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Thuja occidentalis, commonly known as white cedar or arborvitae, has a long history of use in traditional medicine, particularly in Native American and European herbal systems. It has been used for various ailments, including infections, especially those of viral origin such as warts (which are caused by the human papillomavirus, HPV). The primary active compound in Thuja is thujone, along with other essential oils and flavonoids, which have demonstrated mild antiviral and immunomodulatory properties in vitro. Historically, Thuja preparations (such as tinctures, ointments, and teas) have been applied topically or taken internally to address viral infections, most notably warts, respiratory tract infections, and other skin conditions believed to have an infectious etiology.

However, scientific validation for these uses is limited. Some small laboratory and animal studies have shown that extracts of Thuja can stimulate immune cell activity and may have modest antiviral effects, but well-designed human clinical trials are lacking. The use of Thuja for viral infections remains primarily justified by traditional usage rather than robust scientific evidence. Most modern herbalists and practitioners use Thuja cautiously, given the potential toxicity of thujone at higher doses. Therefore, while there is a traditional basis for using Thuja to support or treat viral infections, the scientific evidence supporting its efficacy is weak, meriting a low evidence rating.
