Essential Oils
Essential oils (/ɪˈsɛnʃəl ɔɪlz/), also known as volatile oils or ethereal oils, are concentrated hydrophobic liquids containing volatile aroma compounds from plants. The term "essential" refers to the extraction of a plant's quintessence, a substance regarded as embodying the plant's distinctive characteristics.
Etymology
The term "essential oil" is derived from the idea of the "quintessential" element, proposed in ancient times to be the fifth element after air, fire, earth, and water. This "quintessence" was thought to be the spirit or life force of the plant, and distillation or evaporation of the plant material was believed to remove this spirit for human use.
