Avoid this essential oil during pregnancy
These oils are contraindicated in pregnancy. Clary sage, myrrh and jasmine are uterotonic (clary sage is used deliberately to strengthen labour contractions). Wintergreen and birch are largely methyl salicylate — a salicylate load comparable to aspirin. Sage, wormwood, tansy, thuja, hyssop and rue are high in thujone or similar neurotoxic ketones. Aniseed, fennel, tarragon and basil oils are estragole-rich.
