By studying the effect of aromatherapy on
the fetus, Bastard and Tiran (2006) reported
that essential oils can cross the placental barrier
and be transferred to the infant via breast
milk; however, this does not imply the risk
of toxicity as lavender aromatherapy (inhaled,
incense or massage) is not harmful to the fetus
(Bastard and Tiran, 2006). Furthermore, Burns
et al (2000) reported that aromatherapy not only
leads to reduction of stress and anxiety during
delivery, but also decreases the consumption of
painkillers up to 2% and, as a result, can reduce
the costs of care.
