While aromatherapy proponents claim that aromatherapy is a natural path for relieving numerous health problems, the skeptics are being skeptic and are dismissing such claims.

NAHA (National Association for Holistic Aromatherapy) defines aromatherapy as “art and science of utilizing naturally extracted aromatic essences from plants to balance, harmonize and promote the health of body, mind and spirit." These essences are then distilled into "essential oils" - highly concentrated aromatic extracts - that are derived from a "variety of aromatic plant material, including grasses, leaves, flowers, needles and twigs, peels of fruit, wood and roots.” The most popular essential oils sold are eucalyptus, geranium, lavender, lemon, peppermint, rosemary, and tea tree and they can be found either on the internet or health-food stores.

Aromatherapy supporters claim that their kind of therapy is helpful in relieving arthritis pain, nausea and drowsiness.

The opponents, on the other hand, feel that aromatherapy is nothing more than a set of products with odors. Until different is proven, they are not changing their minds.

The truth is that there has been little research about aromatherapy benefits and the knowledgeable say that there is no logical explanation behind aromatherapy philosophy and its ability to change the course of a disease. They also claim that it could cause adverse reactions due to irritation odors cause in some people.

Furthermore, aromatherapy is unregulated and there is no state license for aromatherapists in the United States. Most aromatherapy practitioners are licensed acupuncturist or registered nurses that have incorporate their aromatherapy training with these other professions.

Certain studies have showed benefits from smelling odors. Back in 2005, lavender aromatherapy helped study participants feel more "vigor" the next morning, after having breathed in distilled water previous night. Another study from 2006 showed that aromatherapy, combined with massage, helped new mothers feel less "blue" and anxious after delivery.
