This remarkable extract of the Australian plant Melaleuca alternifolia has powerful natural antifungal properties. Douching daily with a 1 percent solution in water (or, once a week, soaking a tampon into such a solution and inserting it into the vagina as a pessary, leaving it there for no more than 24 hours) can be very helpful as a natural treatment for vaginitis or cervicitis. This approach is useful whether the cause is candida or trichomonas. Tea tree oil can also be used as a gargle or mouthwash (one drop in a tumbler of water) for oral thrush, or applied directly onto the skin as an ointment. It is somewhat irritating to the skin if used neat as an oil, but there are many products with a 15 percent tea-tree-oil content that are relatively nonirritating and are great antifungal supplements.
