Chinese Medicines Section

About the Section

Chinese medicine samples
Chinese medicine samples

This Section was established on 7th October 1998. Its major responsibilities are to carry out safety monitoring of proprietary Chinese Medicines and Chinese herbal medicines on sale to the public and to conduct development work on analytical methodology.



Responsibilities

This Section examines Proprietary Chinese Medicines and Chinese herbal medicines submitted by the Department of Health.

Around 50,000 tests on Chinese Medicines samples are conducted each year in the Section. Proprietary Chinese Medicines samples are examined for heavy metals/toxic element content and any adulteration by western drugs. Chinese herbal medicines are analyzed for pesticide residues and heavy metals/toxic element.
