Robert Tisserand is one of the most influential figures in modern aromatherapy, especially in the English-speaking world. With more than fifty years of experience, he helped introduce aromatherapy at a time when reliable information was scarce. His early work laid the foundation for aromatherapy to be taken seriously as a structured practice rather than a fringe or mystical tradition.
Tisserand first gained wide recognition with The Art of Aromatherapy in 1977, one of the earliest comprehensive English texts on the subject. The book brought together traditional uses, emerging science, and practical guidance, making aromatherapy accessible to practitioners and the public alike. For many, it served as a gateway into understanding essential oils beyond simple fragrance or folklore.
As the field grew, Tisserand shifted his focus toward safety, chemistry, and evidence-based practice. He became known for emphasizing proper dilution, contraindications, and toxicological limits, challenging unsafe or exaggerated claims. This approach helped protect users and practitioners while raising professional standards, even when it meant confronting popular but risky trends within the aromatherapy community.
His most authoritative contribution is Essential Oil Safety, co-authored with Rodney Young. This reference work is considered the gold standard for professionals, educators, and clinicians worldwide. It compiles research on dermal limits, drug interactions, phytotoxicity, and internal use, offering clear guidelines rooted in scientific data rather than opinion or marketing language.
Through the Tisserand Institute, he continues to educate professionals globally with courses, research articles, and safety resources. His influence is quiet but structural, shaping how aromatherapy is taught, regulated, and practiced. While not universally popular with casual users, Tisserand’s legacy rests on credibility, rigor, and a long-term commitment to making aromatherapy safer and more trustworthy.
