I have been in love with essential oils for a few years now. In fact, there was a time when this love became a bit too much and my mom used to comment that my room smelt like a spa!

Essential oils can help you deal with certain ailments if used in the correct amount and with precaution. So when I became pregnant, I wondered if these oils I had grown to love so much would affect my little one or complicate my pregnancy.

Blame it on the pregnancy hormones, but during pregnancy, I guess every mom to be starts to put everything they do, under the scanner.

If you are pregnant and love essential oils then today’s post is for you. Today we will discuss whether you should be using or ditching essential oils during pregnancy.

Before we start off, I will tell you a little something about essential oils.

What are essential oils?

 If you have visited a spa, chances are that you would fallen in love with the calming aroma wafting out. That is the work of essential oils.

Essential oils are extracted from plants or flowers. They are called essential not because they are vital to us, but because it contains the essence or fragrance of the plant they were extracted from. They are volatile and hydrophobic.

There are many methods of extraction of these oils. They include

General uses of essential oils:

Essential oils have been around since ancient times. Since olden days people have used these oils in a variety of ways in their day to day life.

Essential oils happen to be an important part of the cosmetic and beauty product world. I am sure you would know of many soaps and body washes that boast of the benefits of essential oils.

Let us take a look at how these find their way into our lives.

Essential oil uses vary according to which plant they come from, but certain general uses are-

  • Adding fragrance to soaps, perfumes, cosmetic products
  • Flavoring food and drinks

  • Adding fragrance to incense sticks
  • Added to medicines
  • Added to massage oils due to their therapeutic properties

Essential oils during pregnancy:

As I mentioned before essential oils are used to treat certain ailments.

Now while the conventional medicines may not recognize the benefits of these oils, there are many people who have been using essential oils in home remedies. If used the right way, most of these oils are safe.

But some can be detrimental for you and your baby if used when you are pregnant. I am talking about taking pure essential oils in various home remedies.

60 Essential oils to avoid during pregnancy phase:

Essential oils can be good for you, if you know what to use, how to use and when to use it.

Any discussion on essential oils and pregnancy can stir up a few contradictory arguments. That is because some essential oils can be bad for you if taken during your pregnancy. There are contradictory views on which are safe and which are not. Here I have posted the reason why each oil should be avoided.

#1. Aniseed – This essential oil should be avoided as it contains anetholes. Due to this factor, it may cause eostrogen to increase in the body but for pregnancy it is not favorable.

When to stay away from all essential oils while pregnant?

The fact that there are not enough research to show the effects of essential oils on pregnant woman and the baby, makes you feel wary.

While I have listed certain essential oils that shouldn’t be used by expecting moms, if you have any history of complications or certain health issues, stay away from all essential oils or take the advice of a doctor if you can’t do without any particular oil.

The reasons to avoid these oils during pregnancy include

  • Having a history of miscarriage.
  • Having had bleeding from vagina at any time, during the course of pregnancy.
  • Having diseases of the heart, liver, kidney, and thyroid.
  • Having epilepsy
  • Having blood clotting disorder

Points to consider while using essential oils during pregnancy:

Essential oils are really potent and hence you should exercise caution while using it.

If you have been using any oil and have already spoken to your doctor about it, then you can continue. But if you are a first time user who has just gotten clearance and are going to use it for the first time, keep these tips in mind.

  • Buy pure oils only

The oils blended with artificial fragrance and colors might be cheaper but won’t be as effective.

  • Check the chemical name on the bottle

For instance there are many varieties of eucalyptus oil. Do not forget to check if the scientific name corresponds to what you want to buy.

  • Do not use it directly on the skin

Do not make the mistake of thinking that more means better here. As these oils are concentrated a drop or two will do the trick. Using more will lead to skin sensitivity, irritation etc.

  • Do not ingest

I repeat do not ingest these as ingesting essential oils can be harmful.

  • Storage

When it comes to essential oils, storage is important. Always buy oils that are sold in glass bottles. Plastic and rubber won’t stand a chance against the potent oils. Also store it in a cool dark place as these oils are highly volatile. And keep away from the little ones.

  • Read the instructions

Like for all products, do not forget to read the instructions to see if it has any warnings.

Disclaimer: There may be other essential oils that I have not included in the list but could be harmful to you or your little one.

While a lot of essential oils have been used as alternative medicine, it is mandatory that you get it cleared by your doctor as something that suits one may not suit another. Also you medical history can cause you to react negatively to certain oils that are considered ‘safe’.

Essential oils may be good, but when you are pregnant it is always best to be extra cautious. So if you hear that a certain oil is good for say, treating nausea, always check if that can be used during pregnancy.

The next step is to ask the doctor, if it is safe for you. Then follow the instructions on how much to use. We should only use the amount that is meant to be used.

During the pregnancy phase, the safe amount would usually be lesser than what you can use normally. Follow these simple tips and you are good to go.

Hope this article helps expectant moms to know about essential oils to avoid during pregnancy.
