"Essential oils like lavender and rose can be excellent adjunctive therapy to many health issues like inflammation, pain, and high stress or anxiety levels," Trattner says. "And they can be used as the first line of defense to prevent conditions from developing or worsening. Do I recommend them to my patients? All the time—and I’ve been practicing for over two decades. But they aren’t one-size-fits-all, and they aren’t magic potions, either. If there’s too much pain or you’re facing a severe disease, then it’s time to take something stronger or talk to your doctor to create a cohesive plan of action."
An essential oil is a concentrated hydrophobic liquid containing volatile (defined as "the tendency of a substance to vaporize") aroma compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetherolea, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is "essential" in the sense that it contains the "essence of" the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term essential used here does not mean indispensable as with the terms essential amino acid or essential fatty acid which are so called since they are nutritionally required by a given living organism. In contrast to fatty oils, essential oils typically evaporate completely without leaving a stain or residue.
