When used for essential oils, the term “essential” does not mean that the oil is an indispensable compoud, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a given living organism.
When used for essential oils, the term “wesentlech” heescht net datt den Ueleg en onverzichtbare Compoud ass, sou wéi mat de Begrëffer essentiell Aminosaier oder essentiell Fettsäure, déi sou genannt ginn well se nährstoffaarme vun engem bestëmmten liewegen Organismus noutwendeg sinn.
