Essential oils have also shown to improve learning, memory and ability to focus. Both stimulating and sedative oils can be useful, as oils like peppermint can improve sustained attention over a longer period of time, while oils like lavender can be useful for people going through tough exercises or situations. Furthermore, they can be useful in relieving agitation in individuals with dementia. This is due to their calming and sedative effects. (10)
Especially if skin sensitivity is a concern, definitely ALWAYS dilute your essential oil with a common neutral carrier oil (also called base oils) before application. Carrier oils are typically cold-pressed oils and do not evaporate like essential oils do, but they can go rancid where essential oils will not. Your choice of carrier oil will depend a bit on preference of smell, texture, and sensitivities to avoid allergic reactions. Popular choices for carrier oils are coconut oil, sweet almond oil, jojoba oil, avocado oil, sunflower oil or grape seed oil.
In the era of modern medicine, the naming of this treatment first appeared in print in 1937 in a French book on the subject: Aromathérapie: Les Huiles Essentielles, Hormones Végétales by René-Maurice Gattefossé [fr], a chemist.

With neuroprotective effects and cognitive performance boosting abilities, essential oil benefits have helped many people who are suffering from neurodegenerative diseases like Alzheimer’s and dementia. In a scientific review published in Frontiers in Aging Neuroscience, researchers found that because essential oils possess powerful antioxidants that work to inhibit free radical scavenging, they help to naturally improve brain function and reduce inflammation.
DO: Learn to compare apples to apples when shopping for oils. Anise, Lavender, Bay, Cedarwood, and Eucalyptus are examples of the common names of plants used to create essential oils. There, however, are different varieties of each of these plants. To differential these varieties, the botanical name (also referred to as the Latin name) is used to tell them apart. For instance, two different oils are referred to as "Bay essential oil," yet they come from two different plants. The properties and aroma of each oil do differ as does the general cost between the two. It, therefore, is important to pay attention to the botanical name. In the case of Bay, the common botanical names for the two oils used in this example are Pimenta racemosa and Laurus nobilis.

There are three different categories of oils: top notes, middle notes and base notes. Generally, top notes are more stimulating, uplifting and refreshing and base notes are more sedating and relaxing, though this is not always the case. Whilst not always strictly accurate, another good general guide to this is that citrus oils (Lemon, Lime etc) can often be top notes, uplifting and stimulating, whereas floral oils (Lavender, Jasmine, Ylang-Ylang, Rose etc) are more middle to base notes and more relaxing.

There is no good medical evidence that aromatherapy can prevent or cure any disease. For cancer patients, aromatherapy has been found to lower anxiety and depression symptoms. In 2015, the Australian Government's Department of Health published the results of a review of alternative therapies that sought to determine if any were suitable for being covered by health insurance; aromatherapy was one of 17 therapies evaluated for which no clear evidence of effectiveness was found.
