When it comes to rest and relaxation choose essential oils that have warming and grounding qualities. Essential oils such as Sandalwood, Frankincense and Mandarin, will provide a sense of peace and calm. Frankincense will not only relax but also draws us into the present moment because it deepens the breath. When seeking to alleviate cold and flu symptoms, choose oils which have decongestant and expectorant properties such as Eucalyptus, Cedarwood and Lemon. In addition, all essential oils are antibacterial to varying degrees. That makes them very valuable as antiseptics because they are able to kill germs yet without harming tissue like many synthetic antibiotics.
