The purpose of this study is to determine the most efficient method of removing sulfur dioxide from traditional herbal medicine (hanyak) by slow boiling using a traditional pipkin and an electronic slow boiler. By boiling a hanyak batch containing] 56.4ppm of sulfur dioxide for one hour using a traditional pipkin, 96.7 percent of the sulfur dioxide was removed, while two hours of slow boiling removed ]00 percent. Among different cover materials placed over the pipkin during the slow boiling process including the traditional Korean paper (hanji), regular hanji, filter paper and regular paper, the traditional hanji produced the best performance of sulfur dioxide removal. The initial pH level of the traditional hanji was] 0.03. After one hour of slow boiling hanyak batches in a traditional pipkin covered with traditional hanji, where each batch contained sulfur dioxide of 48ppm, 193ppm, 753ppm and 1,506ppm respectively, the pH level of the hanji cover material was reduced to 9.37, 9.14, 8.9 and 8.03 in respective cases. Our experiment using an electronic medicine slow boiler showed 82.8 percent removal of sulfur dioxide after one hour of slow boiling a hanyak batch containing 753ppm of sulfur dioxide. When hanyak batches were boiled by placing traditional hanji, filter paper, active carbon and hardwood charcoal separately in the middle area within the electronic slow boiler, the sulfur dioxide removal rate was 73.6 percent, 72.8 percent, 73.9 percent and 69.5 percent, respectively. When charcoal was added so as to remove toxic materials from the hanyak, its presence impeded the sulfur dioxide flow and thus reduced the removal efficiency contrary to our anticipation.

Herbal medicines have been used worldwide, particularly in the Far East countries, for thousands of years. Herbal medicines comprise complex mixtures of different phytochemical substances, and their nature may vary substantially depending on many factors related to the cultivation condition, area and harvest time. The processing of the herbal medicines significantly affects their pharmacological and toxicological properties. In this paper, we discuss current research that deals with the techniques for processing Chinese herbal medicines. These results will provide a scientific basis for developing new techniques for the processing of herbal medicines.

This study was conducted to improve the current regulation guidelines for developing traditional Korean medicines with effectiveness and productivity, in order to cope with the upcoming ICH on specifications on oriental herbal drugs. Also, major purposes of this study are to motivate R&D and to pioneer foreign markets for domestic herbal drug companies. First, after examining concepts of traditional Korean medicines and comparing the numbers and differentiation of herbal drugs registered on Pharmacopeia among Korea, China, and Japan, the current new drug development requirements for traditional Korean medicines were reviewed in detail, followed by comparison of foreign regulation systems including USA, EU, China, and Japan. Second, empirical cases on failure of development for new traditional Korean medicines under the current regulation system in the domestic companies including Dong-A, Kwangdong, and Samchondang, were collected and analyzed. As a result, hanbangsaengyak, the new category for traditional Korean medicines was newly developed on the basis of scientification of data between saengyak and hanyak, from the perspectives of harmonization between oriental medicine and western medicine and of balance between food and drug, in terms of industrialization, publicity, modernization, and effectiveness of administration. In addition, the new regulation requirements for the new hanbangsaengyak preparations were discussed by establishing principles of reinforcing preclinical test and of simplifying clinical trials in Korea. Finally, the further researches to articulate the complete specifications for pre-clinical and clinical requirements for traditional Korean medicines were strongly suggested.

Hanyak, Korean herbal medicine is defined as the herbs understood and explained by traditional Korean medical theories. Considering this definition, there are broad prospective of every species being consilienced and utilized as Korean herbal medicine. Most varied plant species are in tropical regions, and its of these regions posses its own particular traditional medicine. Brazil posses the most varied and abundant plant species and also characteristic traditional medicine, formed by the combination of native indians and immigrants from Africa and Europe. Brazilian traditional medicine are practices by 'garrafeiros', 'raizeiros', or 'curandeiros' and in Caatinga uses herbs in ritual ceremonies. But threatened by modernization, these knowledge may be vanished in a prompt time. Therefore we carried this research in the propose of understanding as well as preserving their traditional medical knowledge. We revised publications about the medical plants and summarized 314 species of 94 families according to repetitive references. The most cited families were COMPOSITAE, LABIATAE, LEGUMINOSAE, RUBIACEAE, SOLANACEAE, UMBELLIFERAE, VERBENACEAE. Also cited major medical efficacies which further medical uses in combinations or modification of current traditional Korean medicine should be studied. This study provides overall prospect of the plants resources of Brazil and their uses. It may serve in the consilience and understanding of varied traditional medicine by traditional Korean Medicine.
