Cedarwood oil has a sweet, slightly camphoraceous, and woody-balsamic scent. The oil is a powerful antiseptic, used particularly for respiratory and urinary tract infections. It is a mucolytic (breaks down mucus), which makes it an excellent treatment for catarrhal conditional, especially chronic bronchitis. It is also used extensively in incense, as a preservative and as an insect repellent. Its mildly astringent and antiseptic properties make it a good treatment for acne.
