There are many different schools of thought about what is safe and what is not for baby and mother during pregnancy and lactation.  At Selah we have decided to follow the advice given by Robert Tisserand and Rodney Young in their book, Essential Oil Safety (2nd edition), for many reasons.   They are very conservative on their allowances, they have based their reasoning on sound research and testing and their information is the most up-to-date, as this book was published in 2014.

These are the Selah Essential Oils and Blends that should be avoided and used with caution during pregnancy.  Remember, we are following Robert Tisserand and Rodney Young's safety information that can be found in their book, Essential Oil Safety, 2nd Edition (2014) on pages 152-156.

PLEASE NOTE: 

If you use another brand of essential oils, check their safety before using.

A note about Peppermint oil and Pregnancy:
We have found that several professionals recommend that peppermint not be used by pregnant women.  However, Tisserand and Price both categorize peppermint as OK.  In an effort to give you only the best information possible, we contacted Mr. Tisserand and asked his opinion regarding peppermint essential oil and pregnancy.  This was his reply:
"I have always believed that if peppermint oil was risky in pregnancy there would need to be warnings on peppermint-flavored gum and candy. There is evidence that menthol is safe in pregnancy (p 592 of my book) and there's none that I am aware of that either menthol or peppermint poses any risk. If others think differently, I don't know what their thinking is based on."


Some guidelines:
*Never take essential oils internally when pregnant.
*Never use an essential oil topically without dilution. 
*Never apply essential oils directly to the stomach when pregnant.
*Only use the following suggestions with the approval of your doctor.
*Be sure to always follow your doctor's advice.

A note about photosensitivity and pregnancy:
"Although photosensitizing oils are not a major problem in aromatherapy because possible ill effects are ineffective within 2 hours of administration, pregnant women should take extra care as they have an increased production of melanocytic hormone, which may make them more prone to being affected if the minimum waiting period of two hours is not observed before going into direct sunlight."
(Price, p.239)
