How Essential Oils Interact with the Human Body

Essential oils influence the human body in several ways—through smell, absorption, or ingestion (only under professional guidance). When inhaled, essential oils stimulate the olfactory nerves and send messages to the limbic system, affecting emotions and memory. When applied topically, the compounds in essential oils penetrate the skin and enter the bloodstream, where they can affect physiological processes. The effects vary depending on the oil’s composition and method of use. The Pure Essential Oils highlights the importance of understanding how essential oils interact with biology. This knowledge enables users to choose the right essential oils for their goals, whether emotional support, pain relief, or skin care.
