Nostrums: Aromatherapy Rarely Stands Up to Testing

There is little that aromatherapy has not been claimed to help with at one time or another. It is said to reduce pain and anxiety, bring both energy and relaxation and even make the immune system stronger.But when researchers set out to see if they could prove any of the claims in the lab, they say, most did not pan out.
The researchers, writing online in Psychoneuroendocrinology, did offer evidence that one odor, lemon, really seemed to improve mood. But they found no benefit with pain, stress levels, immune response or healing.
Aromatherapy is a big business, and its roots run deep in folk medicine, say the researchers, led by Janice K. Kiecolt-Glaser of Ohio State University.
But proving whether it works is hard, in part because study participants cannot help but know what they are smelling and so may be influenced by expectations.
For this study, the researchers assessed volunteers’ moods and baseline physiological levels at the start of a series of visits. Then they had the volunteers smell lemon oil, lavender oil or water.
Participants were asked to plunge a foot into ice-cold water for minute, as researchers measured their body’s stress reaction. They were also asked to report their pain level. Researchers also removed a layer of skin and watched to see if aromatherapy helped speed healing
I know for a fact that certain scents make me feel better (say a Choco Chip cookie, fresh from the oven..)
I don’t know if I would call it aromatherapy, but I know it works!
