n the Burns 2007 trial the decision as to which essential oil to
use, together with mode(s) of application was reached through
discussion between the midwife and woman. They could use one
of five essential oils (EOs): Roman chamomile (Chamaemelum
nobile), clary sage (Salvia sclarea), frankincense (Boswellia carteri),
lavender (Lavandula augustifolium) and mandarin (Citrus reticulata).
Aromatherapy was administered for one of the following
reasons: to reduce fear, reduce anxiety, alleviate pain or to augment
contractions. Modes of application included acupressure points,
taper, compress, footbath, massage or birthing pool. Each woman
assigned aromatherapy received one EO (no blending).
In the Calvert 2000 study women were randomised to receive
essential oil of ginger or essential oil of lemongrass in the bath.
Women were required to bathe for at least one hour. All women
received routine care and had access to pain relief.
