Beyond the research

The sourcing trips, the bench work, and the Lab

Dr. Cavanaugh sources botanicals directly from origin. She has traveled to Provence for French lavender and immortelle, to Tuscany for Italian botanicals, and to Iceland for arctic thyme and crowberry. The sourcing is not recreational. It is how she maintains direct knowledge of the supply chain that feeds both the research and the Botanical Lab.

She is an accomplished apothecary maker who has taught formulation for years through her books, the Evidence-Based Handmade Apothecary and the Female Stress Protocol, and through the Botanical Lab's class program at Stovehouse in Huntsville, Alabama.

She is also Scientific Director of the National Association for Holistic Aromatherapy and is regularly a speaker for NAHA conferences and at the Alliance of International Aromatherapists. Her public communication work focuses on research literacy for practitioners who work with botanical compounds.

The Botanical Lab at NRI is where the research becomes something you can touch, smell, and make. It is where 25 years of published work becomes a body oil, a scent experience, or a three-hour class on distillation. Dr. Cavanaugh is there regularly.

She is not a wellness influencer with a lab coat. She is a researcher who also makes things by hand, sources her own ingredients, and answers her own email.
