This week our guest is William Siff, the founder and Chief Formulator of Goldthread plant-based tonics.  One of the most fascinating things about the Goldthread story is that it’s all part of one continuous project. This is really William’s life’s work. It started with an early interest in local flora, expanded into his decision to become a licensed acupuncturist, and took him down a path that included an apothecary, an organic herb farm, and most recently, a line of herbal tonics.
