Aromatherapy Effectiveness Questioned, Study: It Has No Physical Impact, But Lemon Scent Improved Mood - CBS News: "(CBS) Believers swear by aromatherapy, in which certain scents are supposed to have a positive effect on a person's mood or health.
But a recent investigation found that aromatherapy has no physiological effect on people at all."
This will in no way affect sales of aromatherapy products. It has never been about the evidence anyway. Aromatherapy is another pseudoscience with a legion of fact-resistant followers.
