Proprietary Chinese Medicine Testing

Proprietary Chinese medicine (pCm) is now getting more and more popular, in parallel with the Western Drug when more customers are looking for complement Western forms of medicine. Meanwhile, the importance of medicine safety raises the consumers’ awareness, especially when the Chinese medicine incident comes to the light. In general, pCm products are required to meet the requirements in respect of safety, quality and efficacy. Consumption of pCm products containing high level of heavy metal and toxic elements, contamination of pesticide or adulterated with western drug ingredients accidentally, the public may be harmful to their health (side effect e.g.: cognitive decline, palpitation, psychosis, spasms, blood pressure increase etc.).
