Aromatherapy.

Jane Buckle presents the results of a randomised, double-blind trial of two essential oils of two different species of lavender, topically applied on post-cardiotomy patients. The emotional and behavioural stress levels of 28 patients were evaluated pre- and post-treatment on two consecutive days. The therapeutic effects of the two lavenders appeared to be different: one was almost twice as effective as the other, thereby disproving the hypothesis that aromatherapy, using topical application of essential oils, is effective purely because of touch, massage or placebo.
