Aromatherapy is an alternative art of dressing. A woman without fragrance is like coffee without sugar. The highest state of aromatherapy is the unity of body, mind and spirit. Aromatherapy essential oils are mostly extracted from fruits, flowers, leaves, roots or seeds of plants, which have antibacterial, bactericidal and detoxification effects. Heating them for about half an hour can reduce the number of bacteria in the air.
Perfume is a mixture of essential oil, fixative, alcohol and ethyl acetate, which is used to make objects (usually human parts) have a lasting and pleasant smell. Essential oil is extracted from flowers and plants by distillation or liposuction, and fragrant organic matter can also be used. The fixative is used to mix various spices, including balsam, Long Xianxiang, air gland secretions of civet cats and deer. The concentration of alcohol or ethyl acetate depends on whether it is perfume, eau de toilette or cologne. The shelf life of perfume depends on the preservation environment. It can be preserved for a long time, decades or even hundreds of years in a shady place.
