Beyond Photosynthesis: The Plant Pathways Behind Essential Oils

Beyond Photosynthesis closes that gap. Written by educator Christine Sylvester, this is the book that finally connects the biology classroom to the aromatherapy studio — tracing the exact pathway from sunlight and carbon dioxide, through the plant’s hidden secondary metabolism, to the terpenoids, alkaloids, and phenolics that give essential oils their power.

Inside, you’ll find:

• A clear, chapter-by-chapter journey from photosynthesis to essential oil chemistry — no biochemistry degree required
• The five layers of gene regulation that explain why the same lavender plant smells different from morning to afternoon
• A short field guide to key aromatic plants and their chemistry
• Fifteen Social-Emotional Learning activities connecting plant science to self-awareness, mindfulness, and emotional literacy
• A complete 15-lesson course guide and teacher handbook, ready to bring straight into the classroom
• Diagrams, worksheets, and coloring pages designed for teaching, not reading

Whether you’re an aromatherapy student who’s always wondered why a plant makes what it makes, or an educator looking for a curriculum that treats essential oils as real science, this book gives you the language, the pathways, and the tools to teach it with confidence.

Stop treating “biomass” like a locked door. Open it.
