Aromatherapy is a noninvasive, alternative medicine used as an adjunct for labor pain control. A study, published in the Archives of Gynecology and Obstetrics, evaluated the effectiveness of aromatherapy for reducing pain during labor. The randomized controlled trial included 104 primigravidae who were a low-risk singleton pregnancy undergoing vaginal delivery. Aromatherapy was provided to the study group during the first stage of labor. The median pain score of latent and early active phase was lower in the aromatherapy group - 5 vs. 6 and 7 vs. 8, respectively. The mean differences of pain scores between latent and early active phase and the baseline were significantly lower in the aromatherapy group, 1.88 vs. 2.6) and 3.82 vs. 4.39, respectively. Aromatherapy was thus found to be effective in reducing pain in latent and early active phase, and could possibly serve as an adjunctive method for labor pain control without serious side effects.
