What essential oils are safe for pregnancy and which ones should be avoided? It's a commonly asked question that we felt deserved it's own post. We’ve compiled information from trusted sources in the aromatherapy community, erred on the side of caution, and even given you some recipes to use that we’ve personally used or have been used in clinical trials.

Though there aren’t very many clinical trials to pull from, more research is being done all the time. And because it would be unethical to test an expecting mother and her fetus, we rely heavily on the history of safe use.


How do I safely use essential oils during pregnancy?

Dilution, dilution, dilution!

The recommended dilution rate for pregnant women is 1% which is 1 drop of essential oil per 5ml of carrier oil or 6 drops for every ounce of carrier oil. I know it doesn’t seem like much, but trust us… more oil does not mean more benefits or faster results. Your body is doing a lot right now and a lot is changing so don’t weigh your liver down with an excessive amount of essential oils to process.

It’s also not uncommon for pregnant women to have more sensitive skin, so using a higher dilution rate helps prevent a reaction. If the 1% dilution isn’t enough and bothers your skin you can try increasing the dilution to .5% which is 1 drop per 10ml of carrier oil or 3 drops for every ounce of carrier oil. Using essential oils at their proper dilution is considered safe. Using a lower dilution could be a possible risk to the fetus.

In general we don’t recommend casual ingestion, but definitely NOT in pregnancy. Essential oil ingestion is not necessary for most cases and the desired outcome can be achieved with topical application or inhalation. Please check out this FAQ: Essential Oil Ingestion post for a more in depth explanation of our stance.

A Word About The First Trimester

The first trimester is a critical time in the development of the fetus so it’s recommended by many aromatherapists and doctors alike to avoid most essential oils in the first trimester. If you are experiencing nausea though, essential oils have proven to be beneficial in helping ease the intensity. There are a few recipes at the end of this post that are considered safe for the first trimester.
