Due to unstable quality of raw herbs and obsolete production methods, quality control of Traditional Chinese Medicine (TCM) has been an easy target of criticisms from the conventional medical professionals. The difficulties in identifying the ingredients as well as maintaining consistency are formidable obstacles for all manufacturers who dare to put their TCM products to the tests of international standards.

The United States Pharmacopeia (USP) is an official public standards-setting authority for medicines and healthcare products in the United States. USP's standards are recognized and used in more than 130 countries around the globe, and thus are often considered as one of the world's highest quality standards for pharmaceutical products. PuraPharm is the first manufacturer bold enough to put one of its flagship products under the spotlight of USP. After two years of observations and corrective actions, professionals from USP were finally convinced that the quality of a Chinese medicine ingredient could be held to the same strict standards of western medicinal ingredient. PuraPharm's ONCO-Z is thus officially engraved in history as the absolute first USP verified TCM ingredient.

The message shocked the Chinese and western medical sectors, which marked a significant breakthrough in the development of TCM.
