Only the best herbs available go into our products. We try to find herbs that are wild grown and harvested in their natural habitats. Some of our herbs are purchased from farms when we cannot find wild sources. We work closely to monitor the quality of the herbs from the farms and do rigorous testing to ensure that products are free of contamination. We try to follow tradition as closely as possible and stick to ancient recipes as much as possible but we never use animal ingredients in any of our products. Our teas are 100% gluten free as well as Non-Gmo Project Verified.
