Pregnancy and Nursing Safety – Part 2

As an expecting mother and essential oil lover I have found myself with a lot of questions about using essential oils safely while pregnant and while nursing. In Pregnancy and Nursing Safety – Part 1 we discussed safe usage while pregnant and reviewed our updated pregnancy and nursing safe chart. In this installment we will look at using essential oils safely while nursing.

When using essential oils while nursing it is important to keep in mind that they do have the potential to cross over into your milk supply. Normally less than 1% of the amount of oil the mother absorbs will cross over [1] however, “[i]t should also be remembered that infants have an undeveloped capacity for metabolism and renal excretion, and so their ability to clear [essential oils] is relatively impaired.”[2]

With all this in mind, one must consider the following when using essential oils while nursing:

  • The method of use
  • The amount of essential oil used
  • How often you choose to use essential oils
  • How often feeding occurs and in what volume
  • Duration of use
  • Your baby’s age and health

The more often we use essential oils, the longer the duration of use, the higher the dilution rate and the amount of absorption, the more essential oils have the potential to transfer to our milk supply. This can in turn affect our little ones. You can safely use essential oils while nursing, we just recommend keeping your dilution rates low, only using your oils as needed, and using essential oils that are safe for children and breastfeeding. Essential oils should not be applied directly to the chest or breasts while nursing.

If your little one has health issues or is premature please email an Aromatherapist directly at so that we can offer guidelines and recommendations specific to your needs.

  1. Oh dear, I thought Rosmerry was the opposite nursing safe but not.pregnant safe. I’ve been using it in my shampoo and I’m nursing. What are the effects of rosemary while nursing?

  2. Can you comment on lavandin being safe for pregnancy? I thought is was to be avoided during 1st trimester? Thanks.

    1. Sorry, I went back to the part one of this series and see that you addressed first trimester there. Thanks again for this series.

    1. Thanks for the question Kim! Blue Tansy, also known as Tanacetum annuum, can be safely used while pregnant and while nursing. The oil you want to avoid is Tansy, Tanacetum vulgare, which is contraindicated.

    1. Thanks for asking Lauren. There are a few reasons we generally do not recommend using Peppermint while nursing, reducing your milk supply is one of them. In addition, Peppermint is not considered a KidSafe oil. Since there is the potential for the oil to cross over into your milk supply, as well as the possibility of your baby inhaling the essential oil while nursing, we generally do not recommend using it.

    1. Thanks for asking Annie. I wouldn’t advise using essential oils to boost milk supply for your sweet little one. Many of the helpful things in herbs (which can be used) do not translate to the essential oils. For this reason, it’s often said that fennel is helpful. This is the herb that people refer to. The essential oils basil & fennel can be estrogenic and should not be used with or near children. This is true even of lactating mothers, since it may transfer to the milk.

      There are essential oils that can promote a peaceful nights rest and help you to relax which in turn can have a positive effect on milk supply. Some of my favorite synergies for these purposes include Roman Chamomile, Bergamot, and Neroli. You can also use our KidSafe Sweet Dreams to promote sleep or our Spring Blossoms synergy to help you relax during the day. I hope this helps!
