Are juniper berries safe during pregnancy?
Medicinal use of juniper should be avoided during pregnancy, while trying to conceive, and during breastfeeding; a prenatal clinician should guide any question about food-level exposure.

The short answer
Medicinal use of juniper -- tea, tincture, capsules, extracts, or essential oil -- should be avoided during pregnancy, while trying to conceive, and during breastfeeding. Because self-foraged material varies in species and strength, a prenatal clinician should guide any question about food-level exposure rather than assuming a small culinary amount is automatically fine. Do not confuse common juniper (Juniperus communis) with savin juniper (Juniperus sabina), which has a historical use as an abortifacient and should never be foraged or used for food or medicine by anyone.
