In this article, various oils in aroma therapy were studied to see if they facilitate sleep in cancer patients (1). Essential oils may be inhaled by means of an aromastick (a personal inhaler device containing essential oils) as a means of improving sleep. A prospective audit of aromasticks given to help facilitate sleep. Sixty-five aromasticks were given out over a 13 week period. Bergamot (Citrus bergamia) and sandalwood (Santalum austrocaladonicum); and frankincense (Boswellia carterii), mandarin (Citrus reticulata) and lavender (Lavandulaangustifolia) were the essential oils used in the two blends chosen by patients. The authors conclude that 94% of patients reported that they did use their aromastick to help them sleep and 92% reported that they would continue to do so. An improvement of at least one point on a scale measuring sleep quality was shown by 64% of patients following the use of an aromastick.
