Aromatherapy started from 3-4cm of cervix dilatation. In first group, 0.2 ml of essential oil of Peppermint and in second group, 0.2 ml of essential oil of Clove was stained to gas and attached to dresses collar of women and aromatherapy was repeated every half hour. Intensity of labor pain was measured in 3,4cm, 5,7cm and 8,10cm of cervix dilatation and anxiety was measured in 3,4cm and 8,10cm of cervix dilatation.
