Roman chamomile contains only trace amounts of the intense blue component azulene, which gives German chamomile its color. This oil is commonly used in perfumery. It blends well with bergamot, jasmine, neroli and clary sage, lending a warm, fresh note when added in small quantities. The aroma is not long-lasting like that of the German chamomile but it is a mild, soothing oil. This product can be diffused by fan, lamp ring, and cold or warm diffuser.
