Through the nose, the scent is transported into your olfactory mucous membrane sending electrical impulses to the brain, which affect both body functions and emotions. During a massage or aroma bath, the essential oils are absorbed into the skin and enter the blood circulation. Finally, some essential oils can be taken internally. However, we do not advise this and recommend consulting a physician who is also knowledgeable in aromatherapy if you are considering using essential oils internally.
