Compared to the senses of sight and hearing, smell is considered the most faithful sense. Also, the air and smell that a person breathes on a daily basis has a significant impact on human existence and intellectual development. Resting in the wilderness or on the beach is especially good for human health, and it is believed that smell reveals the true nature of things. Plants and natural scents are ethers, or volatile gases, that they contain. Aromatherapy has been used since ancient times in Egypt, China, India, and Babylon, and has been seen as a wonderful art form and science-based therapy that people can apply to their own lives. Aromas are believed to open the soul, elevate the mind, and elevate the mood. It is clear that a pleasant aromatic environment will improve the mood of any person. In terms of its impact on thinking, smell is better than the psychotherapy of a psychologist.
