Physiological and Psychological Effects of Lemongrass and Sweet Almond Massage Oil

Abstract

The aim of this study was to evaluate the physiological effects of lemongrass massage oil on human vital signs. The study design was a controlled trial with a cross-over study. Twenty nine volunteers participated in this study. Blood pressure and pulse rate were measured by the auscultatory method with a contact electrode secured over the left brachial artery. The parameters of assessment were measured before and after using the paired t-test statistical procedure. The results showed that each subject who received one of the three forms of massage once a week for 3 weeks showed a greater reduction in diastolic blood pressure (DBP) than those in the control group. However, there were no significant differences in systolic blood pressure (SBP) or pulse rate. These results suggest that lemongrass oil has harmonizing effects on the function of nervous system. Interestingly, it could be inferred from this study that massage with lemongrass essential oil might also affect emotional and sensation states.
