This information is only a guide and we always recommend checking with your family doctor first before using essential oils during your pregnancy. The use of essential oils during pregnancy is a controversial topic and one that is yet to be fully understood. The main concern during pregnancy appears to be the risk of essential oil constituents crossing over into the placenta. Due to the lack of clear information regarding the toxicity of essential oils during pregnancy, it would be best to adhere to general safety guidelines.
