Abstract
IntroductionAromatherapy is prominent in complementary and alternative medicine. Little endocrinological evidence, however, of the effects of aromatherapy has yet been presented. We used salivary stress marker chromogranin A (CgA) to examine the effects of lavender aroma on women watching a stressful video. MethodsHealthy female university students (n = 23) aged 20–22 years old were randomly assigned to two groups: an aroma group exposed to lavender and an unexposed control group. Both groups watched a stressful video for 10 min. During the protocol, the aroma group was exposed to lavender aroma. Samples of salivary chromogranin A (CgA) were collected immediately before and after watching the video, and at 5 and 10 min after that. ResultsIn the aroma group, the levels of CgA statistically significantly decreased throughout the experimental period. In the control group, there was no such change. ConclusionThe findings suggest that lavender aroma may reduce the stress effects of watching a stressful video.
