In this study, we present the result on the synthetic chemicals contained, as adulterants, in 503 samples of Chinese herbal medicine, which we collected and analyzed during the fiscal year 1999. The result indicates that 13.1% of the samples obtained from the consumer centers of the local health bureaus are adulterated. However, if we include the samples that are randomly taken from local markets by the health bureau officers, the adulteration rate decreases to 8.0%.In the first category, which the supply sources include legal manufacturers of Chinese herbal medicine and medical units (hospitals and clinics of traditional Chinese medicine), approximately 0~7.0% of the samples are adulterated. In the second category, which include Chinese Kung-fu stores, folk medicine stores, unlicensed practitioners and others, the adulterations rate ranges from 0 to 45%. Among them, the Kung-fu stores have the highest rate of adulteration.While the average number of adulterants in each sample is 4.8, there are as high as 25.0% of the samples contain five types of adulterants, and about 20% contain six types. In terms of categories and forms of dosage, the common found adulterants are antirheumatic-analegesics, steroids, antiasthmatics; the forms of dosage include pill (13.9%), capsule (9.5%), and powder (5.2%). In terms of regions, the rates of adulterations found are: in towns (13.6%), in special municipalities (5.9%), in provincial cities (3.3%), and in counties (2.6%).Adulterants found in the Chinese herbal medicine are not only associated with the required categories as indicated above. Other adulterants found are, as ranked by the frequency of use: caffeine, hydrochlorothiazide, thiamine, acetaminophen, indomethacin, diazepam, chlorzoxazone, chlorpheniramine, ethoxybenzamide, phenylbutazone, theophylline, dicyclomine, and diclofenac sodium. |
