I googled "clary sage for labor" and this is just a sample of what I got! ***AND, I also *did* see warnings to NOT use during pregnancy, *except* for during labor.http://www.moondragon.org/aromatherapy/aromabirth.html
This essential oil must not be confused with sage. Don't use sage for the baby's sake - it leaves too high toxic residues in the body. Clary sage is a milder version, although still should be used with care.
Helps respiratory, muscular, and uterine systems.
Facilitates birth; uterine tonic.
Helps breathing by calming the lower part of the spinal cord."http://www.naturesgift.com/childbirth.htm
(there's also an interesting study noted on this page.)
"The list below came from a Doula in British Columbia:
Clary Sage-relieves tension, brings on labor, helps with expelling afterbirth
Geranium Rose-enhances circulation and is good for labor management techniques which focus on breathing
Jasmine-dulls uterine pain, strengthens contractions, promotes birth and increases milk supply. Excellent when mixed with lavender and a carrier oil of Evening Primrose and Vit. E for perinial and cervical massage
Lavender-dulls and eases uterine pain but also increases the strength of contractions while calming the mother. Great for reducing stretch marks!
Myrrh- speeds labor, opens cervix
Neroli-reduces fear, tension, insomnia, apprehension, anxiety
Rose-cleansing effect on the uterus, antidepressant, softens ligaments (easier to open pelvis to push for larger babies and smaller Mamas)"
