Analytical & Advisory Services Division

Chinese Materia Medica Chemistry Section

About the Section

The Department of Health (DH) started up the Hong Kong Chinese Materia Medica Standards (HKCMMS) Project in 2002 to develop standards for commonly used Chinese Materia Medica (CMM) in phases to ensure the safe use and the quality of CMM on sale in Hong Kong. Since its inception, GL has assisted in the development of HKCMMS through the provision of analytical support to DH to develop protocols for commonly used safety tests, conduct inter-laboratory comparison studies on chemical methods developed by the research institutions, as well as trial run studies on the developed HKCMMS. To reaffirm the government's commitment to the establishment of standards for CMM, the Section was established in May 2015 to provide sustainable and steady technical support to DH for carrying out the important inter-laboratory verification and trial-run studies as well as other scientific support to DH for the sustainability of the project.
