In ancient China, olives were translated into "purple stew pot". See.

Olive oil is a light yellow transparent liquid squeezed from olive fruit. It was once called "liquid gold" and is rich in vitamins A, D, E, K and F, which are fat-soluble vitamins easily absorbed by the skin. Especially, the content of vitamin E per 100 g olive oil is 8 mg, which is the highest among all plants.
