aromatherapy during pregnancy

There are so many wonderful ways to use herbs during pregnancy. Aromatherapy is one of these ways and is simply defined as the use of essential oils for healing and health. Essential oils are derived from plants and are 40-70 times more concentrated than the plant in its whole form. They contain 100’s of different phyto-chemicals and play a role in defending the plant against bacteria, fungus and viruses. Various parts of a plant are used and the oils are extracted through techniques such as distillation (similar to making alcohol spirits).

When we are stimulated by smell, our central nervous system responds depending on the attachment we have made to that scent bringing up feelings and memories. For example, a certain smell may remind us of a happy time as a child. Every individual perceives scents differently; something that is pleasant to one person may be irritating to another. This is especially true in pregnancy, a certain smell a woman loved prior to becoming pregnant may turn her stomach once pregnant.

There are many ways to use essential oils but as a general rule do not ingest or use internally while you are pregnant. If you are going to apply topically, ensure to avoid eyes and mucus membranes and always do a patch test first with the essential oil diluted in carrier oil such as coconut or almond. Inhaling an essential oil is one of the fastest ways to benefit therapeutically. Simply breathing the essential oil in through the nose can quickly get rid of, or at the very least, decrease the severity of a headache. One of my favourite recommendations is to use a steam inhalation for sinus and chest colds as it’s a great way to clear congestion. Diffusers clean and purify the air but also create a more relaxing space for those with anxiety and stress. When choosing essential oils, the quality of the product is important as there is no formal body regulating companies that produce the oils. Look for labels that state purity and list only the common or botanical names of the herbs and caution with phrases like “perfume oil” or “fragrance oil” as these might be synthetically derived. The better quality oils tend to come with a higher price but consider what it takes to make an essential oil: 2000 kg of rose petals produce 1 kg of rose essential oil!

Below are my top 6 essential oil recommendations that are safe for external use in pregnancy. Remember to always speak with your healthcare provider prior to using any herbal products in your pregnancy.

1.    Lavender: best known for improving sleep and promoting relaxation, also great for healing burns (when diluted), alleviates itching and stings from bug bites, and can help decrease muscle tension and nerve pain.

2.    Eucalyptus: amazing for clearing chest congestion, headaches (Eucalyptus radiata is the safest form).

3.    Ylang-Ylang: promotes relaxation but is also useful for mood swings to reduce irritation associated with hormone fluctuations and is considered an aphrodisiac.

4.    Sweet Orange: a potent disinfectant used in many cleaning aids and room purifiers but it can also be used to treat low mood and anxiety (get my for my room spray recipe for treating anxiety naturally and tips to help reduce anxiety naturally here).

5.    Tea Tree: a very powerful anti-microbial that can prevent and treat infections including bacterial, viral, and fungal.*

6.    Peppermint: can reduce nausea or morning sickness, calms bloating, and decreases severity of headaches.
