This perhaps offers a modern explanation why the Old Testament prophet Moses used aromatic substances to protect the Israelites from the plagues that decimated the ancient Egyptians. Essential oils are subtle, volatile liquids distilled from shrubs, flowers, trees, roots, bushes, and seeds. Chemically, they are very complex, consisting of hundreds of different chemical compounds. Moreover, they are highly concentrated and far more potent than dried herbs. The distillation of an entire plant may produce only a single drop of essential oil.
Essential oils are also different from vegetable oils, such as corn oil, peanut oil, and olive oil.
They are not greasy and do not clog the pores like vegetable oils can. As the most powerful part of the plant, essential oils and plant extracts have been used medicinally to kill bacteria, fungi, and viruses. They provide exquisite fragrances to balance mood, lift spirits, dispel negative emotions, and create a romantic atmosphere. They are oxygenating and help transport nutrients to the cells of our body. They can stimulate the regeneration of tissue and stimulate nerves.
