Please Note: Essential Oils are concentrated organic chemical compounds from plants, and should always be diluted before application to the skin to avoid irritation. As per the North American Aromatherapy Professional Associations, Hope, Grace and Healing does not promote or encourage the use of Essential Oils internally but more for their aromatic and topical benefits. Ensure that you are aware of the contraindications of the oils that you are using and consult with your doctor or a certified aromatherapist if you have health concerns or questions.
