Abstract :

Chinese Medicinal Materials (CMM) (also known as Chinese medicinal raw herbs) and Chinese Proprietary Medicines (CPM), being natural in nature, have been perceived by the public as relatively low risk. However, they are not completely free from the possibility of toxicity or other adverse effects. Potential harm can occur due to inherent toxic properties of the herbs, as well as contaminants or adulterants in CMM and CPM. Previously, various heavy metal surveys performed by the health authorities of China (in 2016) and Taiwan (in 2006) have indicated presence of high levels of arsenic in Cordyceps and high levels of cadmium in Bulbus Lilii. As China and Taiwan are major suppliers of CMM and CPM in Singapore, such findings in China and Taiwan raised safety concerns regarding raw and finished products of Cordyceps and Bulbus Lilii sold in Singapore. Hence, as a follow-up to a smaller pilot-study conducted in Singapore (2015/2016), a more extensive survey was carried out by the Pharmaceutical Laboratory of the Health Sciences Authority in 2017 to study the levels of arsenic, lead, mercury and cadmium present in 20 CMM samples of Cordyceps and Bulbus Lilii, as well as in 17 CPM samples containing these herbs retailed locally, using Inductively-Coupled Plasma Mass Spectrometry (ICP-MS) technique. The results of this study are presented in this poster; these findings would be useful for facilitating the review of regulatory controls on toxic heavy metals in Chinese medicinal raw herbs and Chinese proprietary medicines, retailed in Singapore.
