the relaxation effect of essential oil from the leaves was performed on 142 healthy female student volunteers from the Faculty of Traditional Thai Medicine, Prince of Songkla University from December 2016 to March 2017 using Taro Yamene’s Formular and G*Power data analysis program. The result indicated that 20 ml of essential oil was the minimum concentration needed for the highest relaxation effect which was statistically significant (p < 0.05) and had the effecting on relaxation with statistically significant (p < 0.05) when compared between the treatment and control group.
