Thuja is an evergreen in the cypress family and is native to eastern North America. The branches, stems, and leaves, which contain the oil thujone, are used in herbal remedies. Native Americans used thuja to treat menstrual problems, headaches, and heart ailments. Thuja is also used as a homeopathic remedy to treat an enlarged prostate in men who are experiencing incomplete urination, frequent urination, difficulty initiating urination, and small urinary volume, as well as for lack of libido and erectile dysfunction.
There is no scientific evidence, however, to support the use of thuja in the treatment of prostate problems. A 2006 study published in Integrative Cancer Therapy did not find carcinosin, sabal, conium maculatum, or thuja to be effective against prostate cancer cell growth or gene expression in mice. (Thangapazham 2006) If you are interested in trying thuja, you should consult a professional homeopath to determine which remedy is best for you.
