Why are most essential oils not recommended for pregnant and breastfeeding women?

During this unique period in some women's lives, it is often tempting to turn to natural remedies, and thus to aromatherapy. However, essential oils contain aromatic compounds with potent effects; they can be counterproductive and pose a real risk to the health of the woman and her baby.

What could be the risks associated with the use of essential oils during pregnancy?

Whether taken orally or applied topically, essential oils should be avoided during the first trimester of pregnancy.

The first risk is associated with the neurotoxic potential of certain essential oils, particularly the ketones they contain. These compounds can cause nervous or respiratory spasms, as well as nausea which can increase the risk of miscarriage. Furthermore, it is possible that the active ingredients in essential oils can cross the skin barrier and the placenta, affecting the developing embryo.

What could be the potential risks associated with the use of essential oils while breastfeeding?

According to a study, essential oil penetrates the skin barrier at a concentration equal to or greater than 3% in a topical formula. As a result, traces of it can be found in breast milk, which can cause respiratory spasms and/or nausea in infants.

What precautions should be taken when using essential oils after the first trimester of pregnancy?

Some essential oils should be avoided throughout the entire duration of pregnancy : Ajowan, Dill, Angelica, Bergamot, Bergaptene-free Bergamot, Juniper, Cajeput, Wild Chamomile, Cinnamon, Caraway, Atlas Cedar, Javanese Lemongrass, Clove, Kaffir Lime, Coriander, Sea Fennel, Turmeric, Frankincense, Tarragon, Eucalyptus Globulus, Eucalyptus Smithii, Sweet Fennel, Galbanum, Juniper, Madagascar Helichrysum, Italian Helichrysum, Khella, Lavandula Stoechas, Greenland Moss, Lemongrass, Lovage, Wild Marjoram, Lemon Balm, Peppermint, Spearmint, Nutmeg, Green Myrtle, Red Myrtle, Lemon Myrtle, Himalayan Spikenard, Sweet Orange, Compact Oregano, Green Oregano, Spanish Oregano, Palmarosa, Grapefruit, Patchouli, Douglas Fir, Scots Pine, Black Pepper, Hemlock, Camphor Rosemary, Cineole Rosemary, Siberian Fir, Balsam Fir, Mountain Savory, Lavender Leaf Sage, Clary Sage, Turpentine,Linalool Thyme, Thymol Thyme, Goldenrod, Exotic Verbena, Vetiver.
