Objectives : To examine the meaning of 'harmonizing all medicinals(調和諸藥)' of Gancao's property to grasp its essence which would further lead to better understanding of formula composition where Gancao is both included and excluded. Methods : Contents on Gancao from previous texts were analyzed and integrated with basic descriptions on qi and flavor, shape and colour, origin, name, etc., to form a single Xiang(象) or image. Further discussion was developed from this point in a way to better understand the harmonizing property of Gancao. Results & Conclusions : Gancao's 'harmonizing all medicinals' property is achieved through its 'mitigate urgency' function. The meaning of 'harmonizing all medicinals' could be understood in terms of both mitigating the whole formula and mitigating each medicinal ingredient. First, Gancao's function of mitigating the whole formula is to mediate conflict that occurs from difference in property among each ingredient where each medicinal's property remains intact to perform its effects soundly. Second, to mitigate each medicinal ingredient is to balance the effects of severly biased medicinals to obtain desired effects. Both approaches are same in essence in that they mitigate urgency to achieve the original goal. Gancao's 'harmonizing all medicinals' is to arbitrate others, which sets Gancao apart from other ingredients to function at a more basal level.

One of the important function of skin is the protection from harmful environments. Many studies were carried out to keep the skin from wrinkling and pigmenting. Skin wrinkle and pigmentation could be caused' by the unusual disruption of connective tissue, the formation of free radicals and the radiation of ultraviolet. In this study, the extracts obtained from 23 different kinds of medicinal plants were examined whether they have inhibitory effect on tyrosinase and elastase as well as free radical scavenging effect. All the extracts examined were obtained by using 70% (v/v) ethanol at $60^{\circ}C$. It has been found that there were two medicinal plants which have positive effects matching with the purpose of this study. The extract of Ephedra sinica stapf shows an inhibitory effect on tyrosinase ($IC_{50}$ = 83.7~$\mu\textrm{g}$/ml), on elastase ($IC_{50}$ = $690{\mu}\textrm{g}$/ml), and also shows free radical scavenging effect ($IC_{50}$ = 29.6$\mu\textrm{g}$/ml). The extract of Betula platyphylla Var. shows an inhibitory effect on elastase ($IC_{50}$ = 498.1$\mu\textrm{g}$/ml), and free radical scavenging effect ($IC_{50}$ = 9$\mu\textrm{g}$/ ml). The aim of the study is to find the natural compounds which have function in skin-lightening, anti-wrinkling and anti-oxidation, with safe and active ingredients in cosmetic.

Background: Fermentation of medicinal plants increases their absorption rate and bioavailability in the body. Astragalus membranaceus has been used as a raw material, but research in its use as a food ingredient is lacking. Therefore, the purpose of this study was to identify the physicochemical characteristics and anti-inflammatory effect of fermented Astragalus membranaceus. Methods and Results: Astragalus roots were fermented using Aspergillus awamori for 4 days and their extracts prepared using hot water. The pH, total acidity (%), and reducing sugar (%) of the extracts were then investigated. The pH and total acidity decreased during fermentation. After fermentation, the pH and total acidity decreased, whereas the reducing sugar level increased. The active ingredients in fermented Astragalus were calycosin-7-O-ßd-glucoside, ononin, calycosin and formononetin. The calycosin contents was highest in the hot-water extracted samples fermented for 4 days. The other components were similar to those in control. Nitric oxide level was lower in the hot-water extracted samples fermented for 4 days than in lipopolysaccharide control group. The sample fermented for 4 days was confirmed to inhibit the production of tumor necrosis factor-α and interleukin-1β. Conclusions: Our results showed the physicochemical properties and anti-inflammatory effects of A. membranaceus after fermentation using Aspergillus awamori. These results indicated that fermented Astragalus membranaceus can be used as a functional food.

Herbal medicines are medicinal products containing a single or a mixture of two or more different herbal substances or herbal preparations as active principles. Recently, much attention has been paid to developing various kinds of fermented herbal extracts, a new type of traditional herbal medicine in the field of Korean traditional medicine. The fermentation of medicinal herbs is intended to exert a favorable influence on bioestability, bioavaliablilty and pharmacological activity of herbal extract in the gastrointestinal tract as well as intensifying the nutritional and pharmacological aspects of the medicinal herbs. The purpose of this study was to investigate biological activities of fermented Rehmanniae Radix by lactic acid bacteria at $30^{\circ}C$ for 3 days in comparison with those for Rehmanniae Radix The fermented Rehmanniae Radix exhibited different chemical profile to Rehmanniae Radix generated with HPLC, indicating production of new ingredients during fermentation. Rehmanniae Radix served as good nutritional sources for the growth of lactic acid bacteria showing increased number of bacteria during fermentation. Toxic effect of the fermented Rehmanniae Radix to cells were not seen judged by the MTT assay. The fermented Rehmanniae Radix exhibited better antioxidant effect than non-fermented Rehmanniae Radix analyzed by a SOD-likely assay. Both hypoglycemic and hypotensive effects of the fermented Rehmanniae Radix were also detected and better than those for Rehmanniae Radix in showing dose-dependent inhibitory effects on alpha-glucosidase and ACE, respectively. In conclusion, fermented Rehmanniae Radix appears to have more biological activities than non-feremented Rehmanniae Radix showing not only antioxidant effect but also cardiovascular protection.

Background and objective: Artemisia argyi has a long history as an effective treatment for various diseases. The detection of environmental pollutant benzo(a)pyrene, a known human carcinogen, in the leaves of Artemisia argyi is cause for concern. For medicinal plant extracts, both a reduction of benzo(a)pyrene as well as the maintained effectiveness of the compound are important. Therefore, in this study, we propose an optimized process for the addition and filtration of activated carbon to reduce benzo(a)pyrene and change the contents of the indicating substance(jaceosidine and eupatilin). Methods: Artemisia argyi EtOH extract containing 36 ppb of benzo(a)pyrene was added to 0.1, 0.5, 1.0, and 1.5% (w/w) of activated carbon for 120 min and filtered using an activated carbon filter 1, 2, 3, and 5 times respectively. The content of benzo(a)pyrene and indicating substances in Artemisia argyi extract were then measured with high performance liquid chromatography (fluorescence and UV detectors). Results: As the amounts of activated carbon powder and filtering cycles increased, the content of benzo(a)pyrene in the Artemisia argyi extract decreased. However, when activated carbon powder 1.5% was added to the extract, and when the activated carbon filter was filtered five times, the results were reduced by 15% and 30~40% respectively. The optimal extraction condition for reducing benzo(a)pyrene was adding 1.5% of activated carbon powder. This resulted in reducing benzo(a)pyrene by 83% and indicating substances by about 4%. Conclusions: Here we present a process for reducing benzo(a)pyrene in Artemisia argyi extract using activated carbon to reduce toxicity and minimize the loss of active ingredients. This approach has potential application within a manufacturing process of various medicinal plant extracts.

Background: Bioactive compounds in plant extracts are able to reduce metal ions to nanoparticles through the process of green synthesis. Panax ginseng is an oriental medicinal herb and an adaptogen which has been historically used to cure various diseases. In addition, the P. ginseng leaves-mediated gold nanoparticles are the value-added novel materials. Its potential as a cosmetic ingredient is still unexplored. The aim of this study was to evaluate the antioxidant, moisture retention and whitening properties of gold nanoparticles (PgAuNPs) in cosmetic applications. Methods: Cell-free experiments were performed to evaluate PgAuNP's antioxidant and moisture retention properties and inhibition activity on mushroom tyrosinase. Furthermore, in vitro cell cytotoxicity was evaluated using normal human dermal fibroblast and murine B16BL6 melanoma cells (B16) after treatment with increasing concentrations of PgAuNPs for 24 h, 48 h, and 72 h. Finally, in vitro cell assays on B16 cells were performed to evaluate the whitening effect of PgAuNPs through reduction of cellular melanin content and tyrosinase activity. Results: In vitro DPPH radical scavenging assay results revealed that PgAuNPs exhibited antioxidant activity in a dose-dependent manner. PgAuNPs exhibited moisture retention capacity and effectively inhibited mushroom tyrosinase. In addition, 3-(4,5-dimethyl-thiazol-2yl)-2,5-diphenyl tetrazolium bromide results revealed that PgAuNPs were not toxic to human dermal fibroblast and B16 cells; in addition, they significantly reduced melanin content, tyrosinase activity, and mRNA expression of melanogenesis-associated transcription factor and tyrosinase in B16 cells. Conclusion: Our study is the first report to provide evidence supporting that P. ginseng leaves-capped gold nanoparticles could be used as multifunctional ingredients in cosmetics.

Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book. "God-Farmer Materia Medica(A.D. 483-496) korean Ginseng was described as the superlative drug: panacea. tonic and rejuvenator.
