Schnaubelt traces the French origins of aromatherapy in parallel with the development of pharmacology. Basing his investigation on the chemistry of body odor and natural human scents, the author explores the molecular makeup of key essential oils: composition, biosynthesis, and healing effects, as well as anti-inflammatory, antihistamine, and antibacterial actions, and antiviral agents. Understanding the chemistry of essential oils allows you to take full advantage of their effects and know how to apply them in the best way.

Schnaubelt analyzes the position of aromatherapy as an alternative medicine in the current social and cultural landscape of science, government and industry. As a method of self-care, aromatherapy empowers the patient, making him less dependent on authority and the medical system.
