Herb Lore's Labor Tincture contains herbs to help initiate labor, to re-start a stalled labor, to detach a retained placenta, to stop postpartum bleeding and to help with an incomplete miscarriage. Labor Tincture will not force labor, but gently encourage it. If the baby is not ready to come, it will not typically work.  Note: Do not use Labor Tincture until the due date to avoid causing premature labor. It is also not for use while nursing. In rare cases, the Blue Cohosh in the combination may either raise or lower blood pressure.
