Our ingredients are selected solely on the basis of quality and purity. We partner with IMPLAD (Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences), the global authority on Chinese herbs, to authenticate and procure raw materials for all of our products. IMPLAD plays a leading role in research on Chinese medicinal herbs and reference standards for TCM.

We manufacture our products in our 100% owned state-of-the-art facility in Zhengzhou, China, under Good Manufacturing Practices (GMP) as established by the US Food and Drug Administration (FDA).

Our Quality Control department, based in Burlington, MA, is separate from the manufacturing facility and is charged with validating product quality. This department arranges for independent analytical laboratories to test finished NPI products for quality and purity using the most advanced equipment and methods such as HPLC and MS.
