Like the other senses, what we smell is transmitted directly to the brain. Studies have shown that the aroma of lavender increases alpha waves in the back of the head, which is associated with relaxation. On the other hand, jasmine scent increases beta waves in the front of the head, which has been found to make you feel more alert. The name of this art is something of a misnomer. The use of essential oils includes, but is not limited to, inhaling their scent.
Aromatherapy is a system of caring for the body with botanical oils.
Sometimes it is the scent that provides the therapeutic value, and other times it works better to take the essential oil internally or rub it on the skin. It depends on the nature and severity of the complaint. Regardless of how the oil is assumed into the body, whether through the skin, the mouth, or the nose, essential oils have long been used to aid in healing. You can enjoy the benefits of scent by placing a few drops of essential oil in your bath, or placing a drop or so on a scent ring, which sits on a warm lightbulb. There are also lamps and diffusers created specifically for aromatherapy.
