All of our manufacturing partners comply with the stringent Chinese Good Manufacturing Practices (GMP). GMP certification means that the site and methods employed in the creation of our products have been subject to a thorough quality control investigation by a government agency and are certified to be in compliance. The GMP certification process covers all aspects of manufacturing, including inspection of the building and grounds, the air and water purification systems, the handling and processing of raw materials, the product manufacturing process, the operation and cleaning of equipment, the training of personnel, and quality control testing and documentation. Adherence to the GMP guidelines ensures that every batch of product is safe and of the highest quality. These standards for manufacturing are the guidelines upon which our teapill, tablet, capsule and extract powder manufacturers base each decision, and allow us to have the confidence to say that they are some of the best herbal product manufacturers not only in China, but also in the world today.
