Essential Oils Used as Medicine When Used for Treatment
DEAR DR. ROACH: In a recent column, you discussed an antihistamine and montelukast for allergies. We use pure essential oil. Lavender is better than drugs. — J.O.S.
ANSWER: I consider any substance that is taken to relieve a medical symptom or to cure or prevent a disease to be medication, or a drug.
For centuries, if not millennia, the drugs in the pharmacopeia mostly were derived from plants. This might mean the whole plant leaf (such as foxglove) or powdered bark (from the willow tree), both of which still are valued and commonly used medications, only they have been purified and standardized as digoxin and aspirin, respectively.
Lavender essential oils can be made several ways, including steam distillation and enfleurage (using a solvent fat to capture the essential oil, then extracting the plant oil with alcohol). All of the methods capture chemicals of interest from within the plant: With lavender, there are over 100 known compounds; among the most sought-after are linalool, perillyl alcohol and linalyl acetate.
