Turmeric essential oil is a concentrated aromatic oil derived from the turmeric plant (Curcuma longa) through a method called supercritical CO2 extraction. Turmeric, a perennial herb native to South Asia, has been widely used for centuries in traditional medicine and culinary practices. The essential oil is extracted from the rhizomes or underground stems of the turmeric plant, where its potent properties are concentrated.
Supercritical CO2 extraction is a sophisticated and advanced method of obtaining essential oils. It involves using pressurized carbon dioxide (CO2) in its supercritical state (neither liquid nor gas) to extract the oil from the plant material. This process ensures that the essential oil retains its full range of beneficial compounds while avoiding the use of harsh solvents, making it a preferred method for producing high-quality oils.
