Aromatherapy is the science of using highly concentrated essential oils or essences distilled from plants to take advantage of their therapeutic properties. Essential oils or essences are obtained from various parts of plants (root, leaf, flower, bark, fruit) and used therapeutically for physical and psychological well-being.The fact that aromatherapy is a noninvasive procedure and is easy to use allows aromatherapy to be widely used . Aromatic oils can be applied in four basic ways. These are topical (touch, compress or bath), internal (mouthwash, vaginal or anal suppositories), oral (capsules or dilution in honey, alcohol or diluent) and inhalation (direct or indirect inhalation with or without steam). Essential oils, which can be applied in various ways, can directly reach the neocortex part of the brain through connections from the limbic system to the hypothalamus via odor. As a result of the effect of aromatic oils on the central nervous system, relaxation, sedation or stimulating effects occur, and thanks to the information flow reaching the brain with the stimulation of the central nervous system, the energy blockage in the body is broken and energy is released as a result. The healing process is supported by the balanced spread of the energy flow to the relevant organs, and physical and mental well-being emerges. Aromatherapy is used in many health fields as well as in womens health.
