The intervention group inhaled lavender oil for 15 days and researchers found that they showed significantly significant differences in their sleep quality compared to the control group that received no form of therapy. Researchers pointed out that lavender oil is a non-invasive, inexpensive and easily applicable intervention for hospital patients who are having trouble sleeping and experiencing anxiety. (21)
After asking the patients to record their headache severity and associated symptoms every 30 minutes for a total of 2 hours, researchers found that the difference between the controls and treated patients was statistically significant. From 129 headache attacks in the treatment group, 92 responded entirely or partially to lavender. In the control group, 32 out of 68 headache attacks responded to the placebo. (19)
While some advocate the ingestion of essential oils for therapeutic purposes, licensed aromatherapy professionals do not recommend self-prescription due to the highly toxic nature of some essential oils. Some very common oils like eucalyptus are extremely toxic when taken internally. Doses as low as 2 mL have been reported to cause clinically significant symptoms and severe poisoning can occur after ingestion of as little as 4 mL. A few reported cases of toxic reactions like liver damage and seizures have occurred after ingestion of sage, hyssop, thuja and cedar oils. Accidental ingestion may happen when oils are not kept out of reach of children. As with any bioactive substance, an essential oil that may be safe for the general public could still pose hazards for pregnant and lactating women.
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)
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.

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.
