Objectives : As Daily Dose of Zizyphi Fructus was designated by the numbers in Treatise on Cold Damage Disease, estimation of Daily Dose was all different among researchers. The purpose of this study was to estimate exact Daily Dose of Zizyphi Fructus. Methods : We fixed the errors in various copy of Treatise on Cold Damage Disease and considered the meaning of the Bee Zizyphi Fructus(肥大棗) and general rules of Daily Dose in Treatise on Cold Damage Disease. So we reduced Daily Dose of Zizyphi Fructus, and compared this with the standard of Zizyphy Fructus in Pharmacopoeia of several Nation and Korean Forest Service. Results : Daily Dose of Zizyphi Fructus was generally 12 pieces; less was for prescriptions which scaled down the amount of ingredients prescribed in the originals; 15, 25, and 30 pieces were used when more was required. The medicinal part was the pulp of fructus, and the dosage of 12 pieces was respectively equivalent to 3 Ryang(兩), and 19.5 g. As defined in the Korean Pharmacopoeia Ninth Edition and standards of forest products by Korea Forest Service, Zizyphi Fructus was medium-sized, and weighs about 1.625 g if properly dehydrated. Conclusions : In short, the proper Daily Dose of Zizyphi Fructus in Treatise on Cold damage Disease was 12 pieces of Zizyphi Fructus and 19.5 g of its pulp, weighing three Ryang(兩). The pulp was estimated to be 1.625 g; it was medium-sized according to the present standard.

Objectives : Herbal medicines were used a lot in the Northeast Asia, traditionally. However, the pharmacopoeia standards in South Korea, China, Japan, Taiwan, and North Korea including many other Asia are different and cause confusion. If the origins are not belonging to same genus, it should be careful to distinguish. In this study, herbal medicines in the pharmacopoeia were analyzed for different genus of origins in order to identify the disruptive items for each country. Methods : The scientific names of herbal medicines (plant based) was analyzed origins from Pharmacopoeias of Republic of Korea, People's Republic of China, Japan, Taiwan, and Democratic People's Republic of Korea. The origins specified differently were examined. Especially, the items which have different genus were analyzed in detail and confirmed for correct scientific name. Results : The analyzed herbal medicines in Pharmacopoeia were all 753 items. 320 items were in only one country's Pharmacopoeia. 237 items were in more than two countries' Pharmacopoeia, but their origins were same on each other. The items which have different genus were 35 items. Conclusions : In general, species belonging to the same genus have similar ecological, morphological, and pharmacological activity. However, species with different genus may have different medicinal ingredients and pharmacological activity. Thus, the items which have same name but different genus are required to analyze for comparison of pharmacological activity. Also, other species belonging to the different genus should be used for different items.

Panax ginseng is one of the most important herbal medicinal plants consumed as health functional food and can be fermented to achieve better efficacy. Lacticaseibacillus, one of the representative genera among lactic acid bacteria (LAB), has also been used as a probiotic material for health functional foods due to its beneficial effects on the human body. To achieve a synergistic effect by using these excellent dietary supplement ingredients together, a novel LAB strain was isolated from the root of 6-year-old ginseng. Through similarity analysis of 16S rRNAs and whole-genome sequences, the strain was confirmed as belonging to the genus Lacticaseibacillus and was named L. casei KGC1201. KGC1201 not only met all safety standards as food, but also showed excellent probiotic properties such as acid resistance, bile salt resistance, and intestinal adhesion. In particular, KGC1201 exhibited superior acid resistance through morphological observation identifying that the cell surface damage of KGC1201 was less than that of the L. casei type strain KCTC3109. Gene expression studies were conducted to elucidate the molecular mechanisms of KGC1201's acid resistance, and the expression of the glycosyltransferase gene was found to be significantly elevated under acidic conditions. Exopolysaccharides (EPSs) biosynthesized by glycosyltransferase were also increased in KGC1201 compared to KCTC3109, which may contribute to better protection of KGC1201 cells from strong acidity. Therefore, KGC1201, with its increased acid resistance through molecular mechanisms and excellent probiotic properties, can be used in health functional foods to provide greater benefit to overall human health and well-being.

Background: Ginseng (Panax ginseng Mayer) is an important natural medicine. However, a long culture period and challenging quality control requirements limit its further use. Although artificial cultivation can yield a sustainable medicinal supply, research on the association between the transplantation and chaining of metabolic networks, especially the regulation of ginsenoside biosynthetic pathways, is limited. Methods: Herein, we performed Liquid chromatography tandem mass spectrometry based metabolomic measurements to evaluate ginsenoside accumulation and categorise differentially abundant metabolites (DAMs). Transcriptome measurements using an Illumina Platform were then conducted to probe the landscape of genetic alterations in ginseng at various ages in transplantation mode. Using pathway data and crosstalk DAMs obtained by MapMan, we constructed a metabolic profile of transplantation Ginseng. Results: Accumulation of active ingredients was not obvious during the first 4 years (in the field), but following transplantation, the ginsenoside content increased significantly from 6-8 years (in the wild). Glycerolipid metabolism and Glycerophospholipid metabolism were the most significant metabolic pathways, as Lipids and lipid-like molecule affected the yield of ginsenosides. Starch and sucrose were the most active metabolic pathways during transplantation Ginseng growth. Conclusion: This study expands our understanding of metabolic network features and the accumulation of specific compounds during different growth stages of this perennial herbaceous plant when growing in transplantation mode. The findings provide a basis for selecting the optimal transplanting time.

The root of Adenophora triphylla is a highly valued medicinal resource that is used to prevent human obesity, cancer, and inflammation, whereas young leaves or sprouts of A. triphylla are used as food ingredients. In this study, we compared the antioxidant and anticancer activities of 70% ethanol extracts of A. triphylla roots and leaves. The leaf extract exhibited stronger 2,2-diphenyl-1-picrylhydrazyl (DPPH)-radical scavenging activity, reducing power, and oxygen radical absorbance capacity (ORAC) than the root extract. Furthermore, the leaf extract was observed to be a potent source of anticancer compounds that were effective against A549 (lung cancer), LNcaP (prostate cancer), SKOV3 (ovarian cancer), and Caco-2 (colorectal cancer) cells. These results indicate that not only the roots but also the leaves of A. triphylla can serve as valuable sources of functional materials in the pharmaceutical industry.

Agastachis herba is so similar in use to herbs that it is called Korea Mint in the West. Western herbs are commonly used as ingredients in cosmetics. However, in Korea, Agastachis herba is primarily used as a medicinal herb. This study aims to compare the effectiveness of one cosmetic ingredient with another cosmetic ingredient. Antioxidant, whitening, polyphenol, flavonoid, and antibacterial experiments were conducted on lactobacillus, yeast ferments, essential oils, and floral water using extracts from Agastachis herba. Antioxidants exhibited significant effects in all samples, while essential oils displayed the highest efficacy in terms of whitening, polyphenol content, and antibacterial properties. Flavonoids exhibited the strongest effect in the 70% ethanol extract. The essential oil had the most significant functional impact. However, it was confirmed that the fermented products that underwent yeast fermentation with extracts were as effective as essential oils.

Objectives : First, to investigate the diffusion of the Daoist Yangseng(養生) Method of Bokshik(服食) as an individual strategy to deal with poor a medical environment in Joseon from mid to late 16th century, through microhistorical methodology. Second, to reveal the process of Bokshik(服食) being recognized as a social phenomenon through the deaths of Bokshik(服食) takers. Methods : 1. Trace the entire treating process of a Scholar-Physicians(儒醫) and evaluate sub-par treatments within the process. 2. Analyze in detail the understandings and assessments of the Scholar-Physician and various related agencies on selected strategies made on the individual level. Results & Conclusions : 1. The dissemination of the Daoist Yangseng(養生) Method of Bokshik(服食), occurred since the mid-16th century within Confucian Joseon. 2. Hidden behind the contemporary medical ideology-'a disease should be treated by medicine'-were realities that were difficult to put into practice due to an insufficient medical system and lack of human and material medical resources. 3. The Daoist Yangseng(養生) Method of Bokshik(服食) was disseminated amid the gap between this ideology and reality, due to its claimed ability that ranged from treating a disease to recovery of health, juvenescence and longevity, with the simple intake of a single prescription consisted of one or two or a handful of medicinal ingredients. 4. As Bokshik(服食) spread throughout society, side effects and deaths came about and became known as well. Bokshik(服食) as a personal strategy on an individual level and its problems became recognized as a social phenomenon through hearsay which includes medical experiences.
