Did you know that our sense of smell has the power to trigger and increase memory, change our mood, and boost our immune system? Aromatherapy is viewed as an art and a science. It has been a healing method that has been used for thousands of years. The Chinese, Egyptians, as well as, many other ancient societies used aromatherapy for medical and religious purposes. In the tenth century the Persians began to distill essential oils which allowed for the oils to be readably accessible in France and Germany.
