Essential oils derived from different plant species have revealed encouraging clinical and preclinical results to reverse cognitive and memory impairments in Alzheimer's disease, a review study has found. The study, “Essential Oils as Treatment Strategy for Alzheimerʼs Disease: Current and Future Perspectives,” was published in the journal Planta Medica. Few compounds exist for the management of Alzheimer's disease, and available treatments only provide symptom relief. Essential oils are composed of a blend of complex, volatile, and naturally derived compounds obtained from plants. These are commonly found in leaves, seeds, flowers, bark, and rhizomes and are extracted through cold-pressing, hydro-distillation methods. Studies have shown essential oils have important therapeutic and pharmaceutical benefits related to cardiovascular disease and cancer, as well as having anti-diabetic, antimicrobial, neuroprotective and anti-aging effects. In fact, aromatherapy for Alzheimer's, which has been used for a long time, has been found to be effective. Researchers in this study reviewed relevant in vitro (laboratory experiments), in vivo (animal experiments), and clinical studies to determine the potential use of essential oils in the treatment of Alzheimer's disease. Scientific databases were explored to gather studies that evaluated the use of various essential oils in different models of Alzheimer's disease from April 1998 to June 2018.
