A book is being edited on the subject by Prof. Vincenzo De Feo of Italy. I contributed a chapter on curry leaf essential oil. I am providing some references on leaf essential oil of curry leaf:

Aromatherapy is an alternative treatment method that uses essential oil vapors from various plants inhaled for health therapy. It affects mood, reduces fatigue and anxiety, and stimulates relaxation. Relaxation is the process of relieving anxiety or stress. It is interpreted as a calm state with a normal pulse. When someone is stressful and anxious, the pulse is higher. Measuring the level of anxiety is done by measuring the heart rate. The research aimed to design an electric aromatherapy device equipped with Atmega 8-based heart rate monitoring as a therapeutic tool that can help reduce various kinds of health problems, one of which is anxiety or stress disorder. The test was carried out by comparing the values of the heart rate monitoring to a pulse oximeter. The oximeter was used as a reference to get high accuracy values. The device is expected to help reduce various kinds of health problems caused by heart problems.
