The safety of liquid-type herbal preparations (47 samples) and beverages containing herbal medicines (18 samples), which are distributed in Gyeonggi province was studied by analyzing heavy metals,benzo(a)pyrene, preservatives and sugar content and to explain the differences between medicine and food based on the labeling standards. The herbal preparation is regarded as medicine and can be differentiated from the beverages containing herbal medicine, which is food, based on the fact that the herbal preparation should be labeled with usage,dosage, efficiency and effect. The mean concentrations of Pb, As, Cd, Hg were found to be 0.014 mg/kg, 0.113 mg/kg, 0.004 mg/kg and 0.003 mg/kg in herbal preparation and 0.009 mg/kg, 0.122 mg/kg, 0.003 mg/kg and 0.002 mg/kg in beverages containing herbal medicines, respectively. In 10 cases of herbal preparations and 6 cases of beverages containing Rehmanniae Radix Preparata (Sukjihwang), benzo(a)pyrene was not found. According to preservative test on herbal medicine, dehydroacetic acid was found less than the indicated content in 6 cases out of 37 cases, which labeled with preservatives, and benzoic acid, dehydroacetic acid and methylparaben were contained with 164.0~198.0 mg/kg, 149.8~272.5 mg/kg and 88.4 mg/kg, respectively, in 3 cases out of 10 cases, which was not labeled with preservatives. Among 16 cases of beverages containing herbal medicines, 3 cases of preservative-labeled beverages had the preservatives, and the rest of all, which was not labeled with preservatives, did not show that they contain any preservative, therefore, it was suitable for the labeling standards. As a result of sugar content test, preservative-labeled products were not appreciably different from the others.

Cosmetics using natural materials which was purchased in retail stores, distributed in Gyeonggi province(32 samples) and online through internet(24 samples) were analyzed by pesticide residues and target preservatives for assessing the safety of it. Natural or organic certifications was identified in 22 samples among 56 samples and most of them were Ecocert. Pesticide residues was detected in 3 samples among 56 samples and each compound and concentration was permethrin(0.6 mg/kg), tricyclazole(11.7 mg/kg) and malathion(0.05 mg/kg). All of it was purchased through internet. Target preservatives was detected in 13 samples among 56 samples and one of them was over the maximum allowed concentration and the rest of them were within the maximum allowed concentration of the respective preservatives. The compound which was over the maximum allowed concentration was benzoic acid and compounds which were within the maximum allowed concentration were sorbic acid, benzoic acid and methylparaben. They were all identified substances in products and the number of detected preservatives in retail stores were higher than online samples purchased through internet. As a result of this study, The method of analyzing pesticide residues and limit in cosmetics using natural materials should be set up as soon as possible and the monitoring about preservatives in cosmetics using natural materials should be conducted on continuously.

This study was carried out to evaluate the safety of circulated oriental medicines and their related preparations in Gyeonggi-do. Total 366 samples (165 species) were analyzed about heavy metals, residual contents of sulfur dioxide (SO₂), and 68 samples were analyzed about preservatives. 17 samples (13 species, 4.6%) were exceeded the legal limit of heavy metal. The concentrations over the legal limit for Pb, Cd, As and Hg were 6.1~19.2 mg/kg,0.4~0.7 mg/kg, 6.9 mg/kg and 0.7 mg/kg, respectively. In particular, the exceeding ratio (5.9%) of the legal limit of heavy metals in foreign products was 3.3 times more than domestic products (1.8%). 13 samples (10 species, 3.6%)exceeded the limit of residual sulfur dioxide and the concentration ranges were 105 to 428 mg/kg in domestic products,on the other hand foreign products were from 114 to 2,468 mg/kg. The mean concentration over the limit of residual sulfur dioxide of foreign products (804 mg/kg) was 2.4 times more than domestic products (338 mg/kg). In studying of the preservatives in oriental preparation, the contents of dehydroacetic acid (48.9~64.1%) in 3 samples of labeled solutions were under the labeled preservative contents and the contents of benzoic acid (139.9%) in 1 sample of labeled pill product was exceeded the labeled preservative contents. The numbers of the detected preservatives in unlabeled solutions, pills and granules were 4, 11 and 7, respectively.
