Speaker: Kenneth Proefrock, NMD

This workshop explores the fundamental principles of acid-base chemistry as they relate to herbal medicine preparation and clinical application. Participants will examine the natural origins and traditional uses of acids and bases in botanical extraction, including historical methods of isolating active constituents. Key topics include the influence of pH on alkaloid expression, comparative uses of vinegar and bicarbonate in extractions, nixtamalization, and the preparation of acetracts and spagyric tinctures. The session will also touch on culinary ash, traditional plant dye practices, and pH manipulation in herbal pharmacy. Emphasis will be placed on practical applications in medicine-making and the clinical significance of extraction methods for potency and therapeutic outcomes.
