Cedarwood oil, typically derived from Cedrus atlantica, has a long history of use in folk medicine and aromatherapy for promoting calm and overall well-being. Research suggests that inhaling cedarwood oil may support relaxation and improve sleep quality, with some studies pointing to its active compound cedrol as a mild sedative that may influence the autonomic nervous system. Preliminary evidence also indicates potential benefits for hair health, as one older clinical trial found that cedarwood oil, used in combination with other essential oils, helped improve symptoms of alopecia areata. Additionally, it has been traditionally applied to soothe minor insect bites and is sometimes explored in attention-related research, though more rigorous studies are needed across all of these areas to draw firm conclusions.
