This fascinating book explores science's new biological understanding of essential oils and their advantages over synthetic drugs. Renowned aromatherapist Kent Schnaubelt reveals how the effectiveness of essential oil applications stems from our common biochemical and cellular heritage with plants. He explains how essential oils preserve a plant's complex natural life-supporting qualities, developed through millions of years of interaction with animals and humans. Reviewing recent research in molecular, cellular, and evolutionary biology, Schnaubelt demonstrates how the multilayered activity of plant essences maintains the integrity of our genetic code. Also explored in this valuable resource are the recent scientific studies showing that pathogens cannot develop resistance toward essential oils as they do with antibiotics and antivirals- thereby making essential oils an amazingly effective treatment.
