Ep. 233: The Hot Tincture Method with Mary Blue

Learn more about the Plant Cunning Conference at:Plant Cunning Conference – In-Person in New York – July 24-26, 2026On this episode, Isaac and AC welcome community herbalist, author, and teacher Mary Blue to talk about the "hot tincture method" and why applying a hot water extraction can dramatically improve tincture color, aroma, taste, and effectiveness while saving plant material, storage space, and time. Mary shares her path from environmental and protest activism into herbalism, her day-to-day running an herb shop and farm, and the mentors and experiences that shaped her teaching focus on herbal actions and solvency. They discuss safety lessons learned from heating alcohol, plant-specific considerations (including mushrooms, marshmallow, comfrey, and milk thistle), glycerins and oils, and how herbalism functions as a form of activism through accessibility, community support, and sustainable practice.
