Dear WW: one more word from root "toco""

Abstract: At least a third of the women giving birth in the United States
received intravenous oxytocin for the induction and augmentation of labor.
The problem of inactive or ineffective labor remains a major challenge for
birth attendants, midwives, and physicians who practice obstetrics. Before
the discovery of oxytocin, traditional approaches to augmentation ranged
from magical and folk interventions to extensive bloodletting. Despite its
wide use the effectiveness of oxytocin augmentation has not been well
studied, and current research raises new questions about its effect on the
brain.
