In the aromatherapy group, gauze impregnated with 4 drops of citrus aurantium aroma (Adonis Gol Daru Company-Iran) will be attached to the neck of the participants. gauzes will be changed every 30 minutes until the cervix has reached 10 centimeters dilation. In addition, in order to avoid bias, for all participants in the aromatherapy group, grain-free adhesives will be applied on four unrelated points (ankle, knee, tooth and jaw) of both ears. Then every 30 minutes in between uterus contraction, a gentle palpation is placed on one of the ears by the project manager, but these points will not be pressed.
In the auriculotherapy group, pressure on the main points of the ear in the external ear (point zero, shen men, sympathetic, thalamus) with the aim of reducing pain and anxiety and the primary points of the ear (uterus (C), uterus (E), Gonadotrophins, ovaries, pelvis , abdomen) with the aim of reducing pain and helping the progress of labor, is applied by a trained researcher who has completed the preliminary auriculotherapy course in 22 hours under the supervision of the Iranian Midwifery Association. To avoid creating bias, auriculotherapy is performed by one person for all research subjects. First, the right ear is cleaned using alcohol, pressure is applied using adhesives containing vacaria seeds for auriculotherapy by ZhongyanTaihe Company, which is available in the Iran, for 30 seconds between contractions, and finger pressure is applied on the vacaria seeds. After 30 minutes, the same points in the left ear are pressed for 30 seconds between contractions, and with finger pressure on the Vacaria seeds. The seeds are compressed alternately on the right and left ear every 30 minutes and each time for 30 seconds until the time of dilation of 10 cm. Finger pressure on the seeds to the extent that the pain is tolerable for the samples. In order to avoid bias, in the auriculotherapy group, a moisten gauze with 4 drops of distilled water will be attached to the collar of all participants. gauzes will be changed every 30 minutes until 10 cm dilation
For all participants in the control group, seedless adhesives will be applied on four unrelated points (ankle, knee, tooth and jaw) of both ears. Then, every 30 minutes, a gentle hand is placed on one of their ears, but these points will not be pressed. In addition, for all participants in this group, gauze soaked with 4 drops of distilled water will be attached to their collars. Gauzes will be changed every 30 minutes until 10 cm dilation.
Also, all three groups will receive the usual maternity care.
For blinding, the outcome evaluator and the participants will not be informed of which group each sample belongs to, and only the project manager who performs the necessary interventions in the labor and delivery room will know about the groups.
