Goldthread is a plant-based tonic company founded by clinical herbalist and L.AC William Siff and his wife, Edith Siff, to empower people to drink more plants. We’re not talking more spinach and kale. Think super herbs, adaptogens, and spices like ginger, matcha, schisandra, turmeric, nettles, and tulsi leaf. We travel the world to source herbs from the regions where they are most potent and cultivate direct-trade relationships with local farmers. Our system of ten innovative and health-enhancing formulations are handcrafted and microbrewed to create a highly functional and refreshing drink!
