“…Although it is still common in some parts of the world, the use of castor oil for IOL has largely been abandoned since the introduction of oxytocic drugs. 10,21,23 A number of studies have investigated its effectiveness. Boel and colleagues 24 examined the hospital records of 612 women who were more than 40 weeks pregnant and attended antenatal clinics on the Thai-Burmese border.…”

“…For labor induction, 77% of midwives reported using herbs, 31% using nipple stimulation, and 23% using sexual intercourse 12 Table 3. lists these herbs in addition to membrane sweeping, with dosages and methods of implementation suggested by various authors 5,13–20 . Many of the suggestions in Table 3 have not been scientifically tested to indicate appropriate methodology, dosage, risks, and benefits.…”

“…Dosage of castor oil is not standardized as seen in Table 3. The exact mechanism by which castor oil stimulates uterine contractions is unknown, but there are some effects that may promote labor 13 . Physiologically, castor oil ingestion by mouth decreases the absorption of fluids and electrolytes in the small intestine, stimulating peristalsis and causing diarrhea 13 .…”

M.S., a healthy 20‐year‐old gravida 2, para 0010 presented at 40 and 2/7 weeks' gestation for a routinely scheduled prenatal visit. She had an uncomplicated prenatal course with a history of termination of pregnancy at 8 weeks without complications 3 years ago. Her due date was based on the date of her last menstrual period. She denied pain, vaginal bleeding, or loss of fluid, and reported positive fetal movement with occasional mild uterine contractions every 30 minutes. Leopold's maneuver revealed an estimated fetal weight of 3200 g in longitudinal lie, vertex presentation. Her vaginal exam revealed a soft, posterior cervix with dilation of 1 cm, 50% effacement, –2 station, with an overall Bishop score of 5. Her membranes were intact. The fetal nonstress test was reactive, with a biophysical profile score of 8/8 and an amniotic fluid index of 12.3 cm. At the visit, the midwife made an autonomous decision to sweep her membranes to encourage spontaneous labor in order encourage labor before 42 weeks so that M.S. would not have to transfer out of the in‐hospital birthing center, M.S.'s desired birthing location. M.S. reported discomfort during the exam. She returned home with counseling regarding fetal movement counting, danger signs, signs of labor, and instructions to eat, drink, and rest if possible in preparation for labor. Two days later, at 7:30 pm, M.S. presented to the birthing center experiencing painful uterine contractions every 5 to 7 minutes since 5:00 pm. She denied vaginal bleeding, reported positive fetal movement and a “gush of clear fluid” at 6:30 pm. Upon triage in the birthing center, the fetal heart rate was 140 bpm with moderate variability, accelerations, and no decelerations. Contractions via tocodynamometer were measured every 4 to 6 minutes lasting 60 seconds. Ruptured membranes were confirmed by sterile speculum exam. Her cervix via sterile vaginal exam was noted to be soft, midposition, 4 cm dilated, 80% effaced, –1 station, and vertex with an overall Bishop score of 10. She was admitted to the birthing center with the diagnosis of early labor, spontaneous rupture of membranes, and reassuring fetal status. Labor was monitored per protocol and she progressed to have a normal spontaneous birth of a healthy baby girl early the next morning.

“…A Cochrane review concluded that breast stimulation appears to be somewhat effective and safe for low-risk women at term (Kavanagh et al, 2005). Castor oil may work, although it has potential serious side effects such as meconium-stained amniotic fluid and maternal nausea (Azhari, Pirdadeh, Lotfalizadeh, & Shakeri, 2006;Boel et al, 2009;Davis, 1984;Garry, Figueroa, Guillaume, & Cucco, 2000;Harris & Nye, 1994;Holmes, 1934;Kelly, Kavanagh, & Thomas, 2001). Petridou et al (2001) reported that physical exertion is related to preterm birth.…”

Many behaviors and substances have been purported to induce labor. Using data from the Third Pregnancy, Infection, and Nutrition cohort, we focus on 663 women who experienced spontaneous labor. Of the women who reported a specific labor trigger, 32% reported physical activity (usually walking), 24% a clinician-mediated trigger, 19% a natural phenomenon, 14% some other physical trigger (including sexual activity), 12% reported ingesting something, 12% an emotional trigger, and 7% maternal illness. With the exceptions of walking and sexual intercourse, few women reported any one specific trigger, although various foods/substances were listed in the "ingesting something" category. Discussion of potential risks associated with "old wives' tale" ways to induce labor may be warranted as women approach term.
