Essential Oils to Avoid While Pregnant or Breastfeeding

Just because something is natural doesn’t necessarily mean it’s alway safe.

This is especially true when it comes to essential oils.

While essential oils can provide numerous benefits to everyday living such as promoting proper immune function, soothing regular aches and pains, encouraging a restful nights sleep, and more — when used incorrectly, or during certain periods in our lives when we should take extra precaution (i.e.; pregnancy, breastfeeding, childhood, with special medical conditions), we can quickly run into some serious trouble.

By their very nature, essential oils are organic substances which not only have the ability to cross the placental barrier during pregnancy, but also have the potential to cross over into your milk supply (and possibly even decrease it) during lactation. (source, source)

What this means…

Essential oils should absolutely only be used with extreme care while pregnant or breastfeeding as they can potentially cause harm to a developing fetus or infant since the ability to clear essential oils from their systems is impaired due to an underdeveloped capacity for metabolism and renal excretion. (source)

Knowing which oils are safest to use, which ones should be completely avoided, how to safely use them, and more are all key factors in assuring your own safety and the safety of your little one(s) while venturing into the wonderful world of EOs.
