The mean pain intensity after massage in the first stage of labor was compared in two groups (Table 3). Overall increasing labor pain intensity in two groups after intervention was decreased. This drop in massage group with lavender was more dramatic than massage only group (from 8.16 to 6.16). This was probably due to the sedating effects of linalool acetate in lavender as a narcotic. In a study on 635 patients who complained of perineal pain after childbirth, six drops of pure Lavandula in comparison to lavender synthetic oil as daily bathroom for 10 days resulted in most patients expressing a satisfaction with lavender essence (Dale et al., 1994). In a systematic review by Smith et al. (2011) on 535 women in comparing aromatherapy with placebo for pain management of labor, there was no difference between groups for the pain intensity and the length of labor. The authors, however, concluded that further research is needed before final recommendations (Smith et al., 2011).
