Can Essential Oils Be Medication? Over the counter without bending over for expensive prescription drugs?

Since antiquity traditional medical practices used pure or absolute essential oils of botanicals, most plants, flowers, seeds, stems, bark, root, extracts, oils, not always edible plants, notice you can eat the fruit of a tree but not its trunk, wood is not edible in the usual sense of food, it does contain a lot of fiber, and one guy on YouTube made a series of recipes of Rice Crispies, with increasing amounts of sawdust added, at up to 15% his testers could not detect the sawdust, and in industrial food processing this is known as adding bulk with cellulose. 

I am not selling Essential Oils or promoting their use or consumption, noting that almost all original Cologne for men or Perfume for women was made for mixes of essential oils with solvents like ethanol and water, base notes, high notes, middle notes, perfumery, olfactory sensation in the nasal bulb is the brains form of liquid gas chromatography, as molecules of things that smell strike the mucus covered nasal bulb, they have surface electrical activity and molecular shapes that plug into certain receptors producing electrical signals to your brain directly, thus smell one of the most intense of all senses, the smell of something can send someone back in their mind to where they first experienced that smell. 

Usually, an essential oil contains thousands of molecules of different substances made by plants. The root vegetable carrot for example, contains more than 40,000 different natural chemicals. Then using an essential oil has something in common with eating real edge foods, border perishables of a grocery store, natural, organic, eggs, meat, dairy, nuts, seeds, salad, spices, salts, fruits, berries, veggies, food that has been part of the human diet for centuries or millennia. Not stuff sold on a shelf in a colorful box like commercial cereals, or snacks sold in plastic or mylar bags like most industrial so called potatoes chips. Mylar is plastic chemically vapor coated with aluminum to block light and oxygen, to improve the shelf life so the industrial seed oils in the UPF do not become rancid as quickly, which reducing financial loses of global tobacco giants that manufacture most of the UPF items that Americans eat.
