Evidence for the efficacy of aromatherapy in treating medical conditions is poor, with a particular lack of studies employing rigorous methodology.[19][20] A number of systematic reviews have studied the clinical effectiveness of aromatherapy in respect to pain management in labor,[21] the treatment of post-operative nausea and vomiting,[6] managing challenging behaviors in people who have dementia,[22] and symptom relief in cancer.[23] However, some studies have come to the conclusion that while it does improve the patient's mood, there is no conclusive evidence on how it works with pain management.[24] Studies have been inconclusive because of the fact that no straightforward evidence exists. All of these reviews report a lack of evidence on the effectiveness of aromatherapy.[17]
You can use essential oils in any number of ways. For example, add them to body lotions or carrier oils, and then apply them topically. Try enhancing a facial toner, shampoo, or conditioner with essential oils. Or incorporate them into liquid soap, toothpaste, or mouthwash. You can also diffuse or spritz the oils throughout a room or pour them into a bath.
