ginger essential oil: the volatile oil extracted from the rhizome of ginger by steam distillation contains almost no high-boiling components, and is a transparent, light yellow to orange liquid.

Water-soluble ginger oil: A light yellow flowable liquid which is extracted with supercritical carbon dioxide and then treated with water. It not only contains volatile components of ginger essential oil, but also contains non-volatile components that essential oil does not have, such as gingerol.

Therefore, the active components and medicinal components in water-soluble ginger oil are more comprehensive.
