26ME24 - Pre-symposium Intensive: Green Extraction Techniques for Botanical Raw Materials: Trends, Lessons, and Optimization Strategies

RECORDING FROM THE MEDICINES FROM THE EARTH HERB SYMPOSIUM

Teas, powders, capsules, salves, creams, and gels reflect time-honored botanical preparation methods passed down through generations. While these traditional techniques (especially hydroethanolic extracts of carefully dried plant material) remain foundational, the past 10–15 years have brought exciting innovations in green chemistry and plant extraction.

In this 3.5-hour class, Kenneth Proefrock explores both the strengths of traditional preparations and emerging technologies such as deep eutectic solvents, ultrasonication, CO₂ extraction, pressurized hot water extraction, cyclodextrins, hydrogels, liposomes, fermentation, and distillation. 

Learn about sustainable, small-scale approaches to modern extraction, accessible equipment options, sourcing raw materials, and essential quality assurance considerations. This is a practical, deep dive into plant chemistry and exploration of innovative, greener extraction techniques.
