Book a Class

We're currently taking registrations for our in-person Honey Pharmacy Workshop at Elderberry's Farm in Paonia, Colorado (June 8-11, 2023). In this four-day immersion we'll practice making rich herbal infused honeys, formulating and creating elixirs, making double-infused oxymels, and creating amazing medicinal meads from our herbal infused honeys. Registration is limited to 20. See you there?


Registration has now closed for our popular Herbal Constituents course that goes in-depth to explore the nature of constituents, structure and function, solubility & extraction, synergy and variability, which plants contain which phytochemicals, how constituents contribute to the actions and energetics of Western herbs, and how to use our knowledge of them in clinical practice. Each class incudes a live two-hour webinar with Lisa Ganora ... If you really want to understand constituents and basic botanical chemistry, this could be the class for you: Two 12-week sessions, each with videos, study guides, PowerPoint decks, handouts, quizzes, a forum, and the live webinars. Sign up for one session or both! Registration will open again in January, 2024.

Herbal Constituents, 2nd. Ed., is a unique addition to the botanical literature

Written in a down-to-Earth style by a clinical herbalist with extensive training in chemistry, physiology and botany, this book is designed for anyone who wants an in-depth understanding of medicinal plant constituents in the context of human physiology.

Herbal Constituents presents the most important concepts and research on phytochemical compounds in medicinal foods and herbs.

Basic Language of Phytochemical Structure

In a clear, step-by-step fashion, the reader is first introduced to the basic language of phytochemical structure including bonding, polarity, functional groups, isomers, and more. This non-mathematical presentation distills the information that is important for understanding the personalities and activities of constituents in medicinal herbs.

Making Herbal Medicine:
Extraction, Solubility, Solvent Polarity & More

These chapters address areas of interest for the botanical practitioner including solubility and extraction of herbal constituents, polarity of solvents and solvent systems, and other influences on solubility, phytochemical stability, and reactivity in extracts. We also explore synergy and variability in herbs and formulas, and the role of standardization.

Herbal Constituent Categories

The book presents a detailed and thoroughly referenced chapter for each of the major categories. Each chapter contains numerous illustrations and explanations of the botanical occurrence and physiological activities of the constituents, and is based on up-to-date research considered in the context of traditional usage.

Extensive Illustrated Glossary

Herbal Constituents concludes with an extensive illustrated glossary having some 250 entries that will be helpful for those needing to review some of the most important concepts and terminology from organic chemistry, biochemistry and phytochemistry.
