The leaves were often utilized to make teas or poultices believed to have therapeutic properties.
One notable traditional use of Thuja is its association with respiratory health. The plant was employed by indigenous communities to address respiratory issues, such as coughs and bronchitis.
The aromatic qualities of Thuja, attributed to compounds like thujone, may have contributed to its use in these contexts.
Additionally, Thuja has been explored in homeopathy. In homeopathic practices, preparations derived from Thuja are sometimes used for skin conditions, such as warts, and as an immune system booster.
It’s important to note that while Thuja has a history of traditional use, scientific evidence supporting its efficacy in these areas is limited, and any medicinal use should be approached with caution and under the guidance of healthcare professionals.
