Aromatherapy in Pregnancy

Q. I have been using aromatherapy oils, but now I am pregnant and I have heard that some of them are not safe to use. Which ones are they and why? P. Chase, Hackney

Dr Guy Staight replies: Aromatherapy is a very helpful and soothing technique, but there are a group of oils which are potentially toxic and should not be used in the early stages of pregnancy, particularly during the first three to four months. They generally are said to induce menstrual flow and can also be used during labour to strenghten the contractions.

The following ones should not be used: Aniseed, Armoise (Mugwort), Arnica, Basil, Birch, Camphor, Cedarwood, Clary Sage, Cypress, Fennel, Hyssop, Jasmine, Juniper, Marjoram, Myrrh, Origanum, Pennyroyal, Peppermint, Rose, Rosemary, Sage, Savory, Thyme and Wintergreen, plus any other oil described as toxic.

Camomile and Lavender are also described as potentially toxic, but can be used with care in small amounts and low dilutions, except in the very early stages when someone has any reason to fear a possible miscarriage. Many Aromatherapists use Lavender in small amounts beyond the sixth month as it can be helpful in relieving backache. If you have seen an Aromatherapist in the past, they will be able to advise you on any particular oils you may be using.
