Aromatherapy is the use of plant material and plant derived substances, (bark, root, etc.) and essential oils to improve not only the physical, but the emotional and mental well being of animals. Certain oils will have anti-microbial, anti-viral properties. Oils can be used for calming influences or to help focus on the issue at hand. It is important that you know the quality of oils being used. Cheap oils are often made with solvents and are not beneficial to you or your animal.
