During the fiscal year of 1997, eight-hundred-and-sixty-three samples of Chinese herbal medicines were accumulated and analysed for synthetic chemicals as adulterants. The results indicated that 12.3% of samples from consumer centers of local health bureaus were adulterated. However, if the samples included those randomly sampled from local markets by the health bureau officers, the adulteration rate decreased to 6.0%.The analysis of the first category of supply sources including samples of legal manufacturers of Chinese herbal medicines and medical care units (hospitals and clinics of traditional Chinese medicine) yielded the following results. Approximately 0-3.9% of the samples were found to be adulterants as were 2.0% of samples of legal manufacturers. The analysis of the second category including Chinese Kung-Fu stores, folk medicine stores, unlicensed practitioners and others yielded adulteration rates that ranged from 0 to 31.6%. The Kung-Fu stores had the highest rate.The average number of adulterants in each sample was 3.7. As high a 25.0% was revealed both in the samples containing two and five kinds of adulterants. About 13.5% of the samples contained four adulterants. Two samples were found to contain seven adulterants. In terms of categories, the common adulterants were antirheumatic-analgesics, aphrodisiacs and steroids.The adulterants found in Chinese herbal medicines were not necessarily associated with the labelled category as indicated. The rank order of occurrence of adulterants is the following; Hydrochlorothiazide, Caffeine, Diazepam, Thiamine, Piroxicam, Indomethacin, Acetaminophen, Chlorzoxazone, Ethoxybenzamide and Mefenamic acid. |
