The Toronto Star featured a DNA barcoding study by University of Guelph researchers July 28. Prof. Steve Newmaster, Integrative Biology, discussed a recent study that found nearly 80 per cent of Chinese patent medicines are mislabelled. The researchers plan to use the techniques developed in the study to test natural health products, assuring quality. The testing breakthrough will benefit industry, consumers and regulatory bodies, Newmaster said. He studies plants and DNA barcodes.
