Essential Oils: Nature's Secret for Health and Beauty

Essential oils are the "essence" of plants, extracted by many different methods, the most common of which are steam distillation and cold pressing. They contain natural chemical compounds, carrying the characteristic aroma of that plant species. Unlike vegetable oils (such as olive oil, coconut oil), essential oils are very volatile and do not contain fat.

The use of essential oils has a long history. The ancient Egyptians used essential oils in the process of embalming and religious ceremonies. In ancient Greece, Hippocrates, the father of medicine, also recorded the use of essential oils for medicinal purposes. In China and India, essential oils are also widely used in traditional Ayurvedic medicine and traditional Chinese medicine.

Steam distillation: This is the most common method. Steam is passed through the plant material, evaporating the aromatic compounds. The mixture of steam and essential oil is then cooled to condense into a liquid, and the essential oil is separated from the water.

Cold pressing: This method is often used for citrus fruits such as oranges, lemons, and grapefruits. The peel is pressed to extract the essential oil.

Solvent extraction: This method uses chemical solvents to dissolve the aromatic compounds from the plant. However, this method is less popular because it can leave solvent residue in the essential oil.

Supercritical CO2 extraction: This is a modern method, using CO2 in a supercritical state to extract essential oils. This method produces high quality essential oils, but the investment cost is high.
