Thuja’s main action is related to its content of stimulating volatile oil. In bronchial catarrh, thuja promotes expectoration and provides systemic stimulation that is especially beneficial when heart weakness is also part of the picture. However, thuja should be avoided in cases in which cough is due to overstimulation (for example, dry, irritable coughs).
Thuja has a specific reflex action on the uterus and may help with delayed menstruation. Because of this property, however, the herb is best avoided during pregnancy. Thuja may also be used for ordinary incontinence due to loss of muscle tone. It has a role to play in the treatment of psoriasis and rheumatism when used internally.
Externally, it may be effective against warts and demonstrates a marked antifungal activity against ringworm and thrush.

Brief History
The botanical name of Thuja is derived from a Greek word meaning to fumigate. In pre-Christian times it was customary to burn sweet-scented thuja wood during sacrificial rites and to ward off evil spirits. The tree was introduced into France from Canada and planted in the grounds of the royal palace at Fontainebleau.
Many Native American peoples prized thuja as a medicine for fever, headaches, coughs, swollen hands, and rheumatic problems. The 19th-century Eclectic herbalists used it as a remedy for bronchitis, rheumatism, and uterine cancer. It has also been used to treat the side effects of the smallpox vaccination.
