Orange is a pleasant scent that has a cheerful and uplifting yet simultaneously relaxing, calming effect that helps reduce the pulse rate. It can not only create a warm environment but can also stimulate the strength and resilience of the immune system and eliminate airborne bacteria. The scent of Orange Oil is believed to enhance cognitive function, thus making it easier to recall memories, especially for Alzheimer’s disease patients. Peppermint can boost energy, clear the respiratory tract, stimulate circulation, alleviate feelings of nervous tension and stress, and soothe feelings of irritability.
