Peppermint is a refreshing mental stimulant if the labor is long and tiring. Relaxing oils can help relieve some of the emotional trauma associated with labor. The inhalation of the vapors from Clary sage has been found helpful to improve the efficiency of uterine contractions towards the end of a long labor. Using aromatherapy for pregnancy and birth is also an age old process. Aromatherapy is usually done to relive tension and promote relaxation.
Massage is especially good for a women during pregnancy to help relax the body and ease discomforts.
Scenting the air can also relax or rejuvenate you, and it's easy to do. Additionally, you can add 2 to 6 drops of essential oil to a cotton ball with a gentle oil such as lavender, place it on your pillow. Sometimes I put lavender on my hand and then rub my hand over the pillow when I'm trying to relax or having trouble sleeping. Remember to use a cold diffuser if you are diffusing oils. Heating with a candle or potpourri burner is not diffusing.
