Aromatherapy. It may smell good, but is it actually good for you?

Researchers are reporting that two of the most commonly used scents in aromatherapy, lavender and lemon, do nothing to heal wounds, relieve pain or enhance immune status. But they did find lemon did briefly improve mood.

Researchers used lemon oil, lavender oil and distilled water on study subjects in different situations to gauge the effects. They say, while lemon oil showed a clear mood enhancement, lavender oil did not. They also add, neither smell had any positive impact on any of the biochemical markers for stress, pain control, or wound healing.

The study appears in the journal Psycho-Neuro Endocrinology.
