The first is olfactory stimulation: aromatherapy uses olfactory stimulation to influence the olfactory system of the brain. When we smell a specific aromatic substance, olfactory information will be transmitted to the olfactory center of the brain through olfactory receptors, which will activate related brain regions, thus triggering specific physiological and psychological reactions.
Followed by chemical composition: essential oil is the core of aromatherapy, and it is a volatile compound with strong fragrance extracted from plants. The chemical components in essential oil can enter the human body through inhalation or skin absorption. These chemical components have antibacterial, anti-inflammatory, soothing, calming, stimulating and balancing properties, which can affect our physical and emotional state.
Thirdly, it is neurophysiological effect: the chemical composition of essential oil can produce physiological effect by affecting the functions of central nervous system and autonomic nervous system. They may regulate the release of neurotransmitters and affect the blood circulation, digestive system and respiratory system, thus promoting the balance and self-healing ability of the body.
Fourth, psychotherapy: aromatherapy also has the component of psychotherapy. Some aromatic substances can adjust brain wave patterns, promote relaxation, improve sleep, relieve anxiety and improve mood. The sense of smell can directly affect the mood and psychological state by connecting the cerebral cortex with the emotional center.
To sum up, the principle of aromatherapy is to comprehensively adjust the physical and mental state and promote health and balance through the olfactory stimulation of essential oil, the physiological function of chemical components and the effect of psychotherapy.
