Essential Oils to Avoid during Pregnancy
Once you conceive, suggestions and warnings pour in from every direction. While some of them may not be so practicable, most of these cautions have some merit to them, as even a seemingly normal thing like drinking a cup of herbal tea may be potentially harmful during this time. Use of essential oils is one such matter, where you need to consider their benefits as well as risks in detail. Some essential oils can work miracles for various common pregnancy ailments, while others may prove potentially life threatening.
Risks of Using Essential Oils while Pregnant
The components and properties of a herb are present in a highly concentrated state in its essential oil . For example, producing 1 pound of pure lavender oil requires over 250 pounds of the herb . So, one drop of lavender oil will have the same properties and effects as 20-25 cups of lavender tea. Due to this reason, experts often recommend using some carrier oil, such as coconut or almond oil, along with essential oils in aromatherapy, especially during the early stages of your baby’s development .
In fact, it is commonly advised to avoid these oils altogether during the first trimester , as over 80% of all miscarriages occur within the first 12-13 weeks .
