Essential oils are not food. Ever. Essential oils consist of volatile organic compounds which comprise a small part by mass (0.01%-20%, it varies) of plants and are distilled out. Most essential oils are highly toxic in large amounts, but can be safely used as flavorings/odorants in small concentrations.

Food oils consist of triglycerides, which are not volatile, and are extracted from foods containing them usually by pressing (mechanically) rather than distillation.
