About the Use of Essential Oils during Pregnancy and Their Precautions


When pregnant, turning to essential oils can be a smart choice. All the changes are stressful enough on your body, and you don’t really have an ally in medicines. We know medicines are very powerful and they can cause serious side effects. When you’re pregnant, the last thing you want to do is endanger your unborn child.


As I’ve told you in one of my previous articles, essential oils are somewhere between herbs and drugs. Herbs are not that concentrated to actually make a noticeable difference. They don’t make a big difference when it comes to more serious conditions like vomiting, for instance. But essential oils can help. They are concentrated substances that can influence the body and help it work better. Plus, they’re natural.


They are a nice way to help your body go through all that pressure and hardship while pregnant. Essential oils also smell very nice, and even if you don’t stand the smell of one, you will still like the smell of another. There are many different essential oils where you could choose from.


During the steam distillation of essential oils, the oil molecules are heavier than water so they will float. Their molecules are also very tiny, and it seems that this is the main safety concern in pregnancy. Because they’re so tiny, those molecules can travel really fast into the blood stream. There is also the possibility of reaching into the placenta. That could affect the baby’s blood circulation.


Because of that, there are many essential oils that are not allowed to be used during pregnancy. Essential oils molecules are solid in fat. So once they’ve done their job inside your body, they will be expelled through the maternal milk.


Before we get to the list of essential oils not to use in pregnancy, let’ see what the precautions are. Because when using essential oils during pregnancy, you must be very careful with the dose, the oil you use and even how you use it.


Precaution Measures to Take When Using Essential Oils during Pregnancy


  • It is extremely important to talk to your doctor before using essential oils. Tell him which one you’d like to use and listen to his advice.
  • Try not to use essential oils in the first 3 months of pregnancy without medical advice.
  • Always follow the recommended dose! You are doing no one a favor by going above the specified dose. Plus, you could be harming your baby without even knowing it.
  • You might want to go slow at first. Try using one drop of essential oil at a time and see how your body reacts.
  • Do not use one type of essential oil for more than 7 days in a row. Luckily, you have plenty to choose from, so use them in turns. If used for a long period of time, essential oils can sensitize the skin. Once it becomes sensitive, it will always be that way.
  • Never use undiluted essential oils on the skin. A 1% dilution means 6 drops of EO per Oz. carrier oil. For your own peace of mind you could add less than that.
  • Don’t apply essential oils on the womb.
  • When you diffuse essential oils, do it for 15 minutes each hour. Also, leave at least an hour pass before switching to the next different essential oil.
  • Epileptic pregnant women shouldn’t use essential oils at all. It would be best to avoid them if you suffer from any other serious illnesses.
  • Also, avoid them if possible in case you have a miscarriage history.
  • Finally, if the symptoms persist for a longer time, you should go to the doctor, a.s.a.p. You don’t want to be anything else but serious when pregnant. Essential oils are just a better way to improve mild conditions. They should never replace prescribed treatments.
