Sagebrush (Artemisia tridentata) Oil

Culinary seasoning is fine, but sage (especially concentrated extracts) is traditionally avoided in medicinal doses during pregnancy — it has a long-standing reputation as an emmenagogue and, at high doses, contains thujone, a compound associated with uterine stimulation.

Sage is one of the classic traditional herbs used specifically to reduce milk supply (used deliberately for weaning) — avoid regular/medicinal use while trying to maintain supply.

Culinary amounts are fine; concentrated sage extracts or essential oil (thujone content) are not recommended for young children.
