What is the Latin term for "essential oil"?

The Latin term for "essential oil" is derived from the roots relating to ether and the characteristics of oils. In this context, "Aetheroleum" correctly combines "aether," which means ether, with "-oleum," a suffix used in Latin that means oil. This term effectively conveys the concept of a volatile oil extracted from plants, commonly referred to as essential oils in modern terminology.

The other terms either do not represent the concept accurately or do not correspond to recognized botanical terminology. "Aetherolum" is not a standard term used in context with essential oils, and "Aetherus" or "Aethericum" do not specifically indicate the oily nature of essential oils. Thus, the choice "Aetheroleum" stands out as the precise and appropriate term for essential oil in botanical and medicinal contexts.
