This article will tell you where aromatic oils are used and applied, how they are classified and how far their traces go back in history.

History

The history of essential oils, according to scientists, has developed in all world civilizations. According to archaeologists, in Egypt 6000 years BC, turpentine was already extracted from plants and they possessed the art of embalming. In China, 4500 BC, they began to study the medicinal properties of plants. In 2700 BC, Emperor Shen-Nun compiled the "Great Herbalist", which described 365 medicinal plants. The Chinese believed that the smell of plants contains magical energies, aromas strengthen human strength and expel diseases. The Greeks in 400 BC discovered the therapeutic effect of plant incense, their calming and stimulating effect. Around 1000 AD, Avicenna first obtained fragrant rose essence by distillation. The Enlightenment brought with it the tradition of using scented water, and from the 12th century, aromatization separated and became an independent perfumery industry. In 1928, the French chemist Gattefosse, when describing the therapeutic effect of plant extracts, introduced the concept of "aromatherapy". This scientific work was continued by the doctor Jean Valnet, who during the Second World War treated the wounded using essential oils and discovered their regenerating and antiseptic properties. Aromatic oils were brought to Russia under Peter I. Snuff and sachets with fragrant herbal powder, which fashionistas sewed into their fluffy skirts, became fashionable. ## Application
