Essential Oil Safety (2nd Edition)

Authors: Robert Tisserand & Rodney Young
Publisher: Churchill Livingstone (Elsevier), 2014

This book is widely regarded as the a standard reference for anyone working extensively with essential oils. Unlike online articles, it provides comprehensive, peer‑reviewed safety data for hundreds of oils.

What It Covers

  • Constituents: Detailed breakdowns of the chemical makeup of most essential oils (like cineole, limonene, linalool).
  • Safety profiles: Clear guidance on safe dilution ranges, toxicity thresholds, and age‑specific recommendations.
  • Side effects: Simplified explanations of possible adverse reactions such as skin irritation, sensitization (developing an allergy over time), or phototoxicity (skin damage when exposed to sunlight).
  • Contraindications: A contraindication means a medical or health condition where using the oil could be harmful. A “do not use if…” warning. Situations where an oil should not be used.
    • For example, peppermint oil may be contraindicated for infants because it can cause breathing difficulties.

Why It’s Trusted: Robert Tisserand is one of the most respected authorities in aromatherapy, with decades of research and teaching experience. Rodney Young is a pharmacognosist (expert in plant‑based medicine) who contributed deep scientific analysis. Together, they created a reference that blends traditional aromatherapy practice with modern toxicology and pharmacology.
