Aromatherapy is a form of alternative medicine that uses essential oils to improve health and well being.
This therapy harnesses the healing properties of plants and herbs. For example, lavender is said to help in reducing stress (and keeping moths away!), chamomile can help with depression, and cinnamon can relieve drowsiness and irritability.
Aromatherapy is a therapy in its own right and therapists who make and use oils to help themselves and others heal using essential essences are called Aromatherapists. However, other healing modalities may also avail themselves of these essences such as massage therapists, chiropractors, nurses, and doctors.
