Objectives: This study aimed to investigate the stability of a decoction using three herbal plants and their major components according to the storage conditions and periods. Materials and Methods: A three-herb mixture (1:1:1) of Glycyrrhiza uralensis Fischer, Artemisia capillaris Thunberg, and Poncirus trifoliata Rafinesqui was decocted and kept at room temperature ($25{\pm}2^{\circ}C$) or cold temperature ($4^{\circ}C$) for 0, 2, 4 or 8 weeks in liquid form in a plastic pack under dark conditions. At time points given, they were lyophilized. 200 mg of powdered samples were dissolved in 1 mL of 90% methanol and then applied to a high performance thin layer chromatography (HPTLC) with glycyrrhizin, 6,7-dimethoxycoumarin or poncirin for quantitative or qualitative analysis. Results: There were no gross changes in HPTLC-based compositional band-patterns of the three herbal mixture according to the storage conditions and period. The major components of each herb, glycyrrhizin, 6,7-dimethoxycoumarin and poncirin, showed slight time-dependent reduction in their contents both at room and cold temperature for 8 weeks. Conclusion: We could conclude that the current herbal decoction is generally safe for the stability at both RT or CT for at least 8 weeks. Nevertheless, we proposed that further advanced studies are required for more multiple herbal mixtures and longer storage periods.

Glehnia littoralis (Umbelliferae), a perennial herb distributed along the coastline of northern Pacific countries, is the medicinal plant used traditionally for treatment of various diseases. This review focuses on the various pharmacological activities of Glehnia littoralis for understanding about its traditional medicinal applications, medicinal uses in the modern society, and potentials for drug development Glehnia littoralis was reported to have anti-oxidant, anti-tumor, anti-amnesic, blood circulation-promoting, immunomodulatory, anti-microbial, and allelopathic activities. However, their mechanisms remain to be clarified. Because Glehnia littoralis has been prescribed in traditional Oriental medicine as a tonic herb, Glehnia littoralis can be better than other chemical drugs and medicines which exert the equal pharmacological activities. Although the activities of Glehnia littoralis are not specifically high-potent with unique mode of action, it may turn out that it can be beneficial to exert multiple pharmacological activities. In view of low toxicity, relative cheapness, presence in the diet, and occurrence in various herbal remedies of Glehnia littoralis, it needs to be prudent to evaluate its properties and applications further.

This study analyzed research methodologies based on network pharmacology to build a new system architecture optimized for Korean Medicine research. Results form studies using network pharmacology were collected and analyzed to evaluate the strength and weakness. Finally, an improved system architecture was proposed. Whether the predicted effects of drugs or herbs from network pharmacological analyses were in agreement with those from conventioanl knowledge of Korean Medicine was evaluated. These results were used to verify the applicability of research methodologies to the modern pharmacology and Korean Medicine respectively. Eighteen papers using TCMSP were collected and analyzed. The results suggest that the research methodology based on network pharmacology is appropriate only for the modern pharmacology but not for Korean Medicine. Information about compound-compound, herb-herb and drug-compound interactions need to be considered. We propose the modified system architecture with those information.

Background: Triptolide, extracted from the herb Tripteryglum wilfordii Hook.f that has long been used as a natural medicine in China, has attracted much interest for its anti-cancer effects against some kinds of tumours in recent years. Artesunate, extracted from the Chinese herb Artemisia annua, has proven to be effective and safe as an anti-malarial drug that possesses anticancer potential. The present study attempted to clarify if triptolide enhances artesunate-induced cytotoxicity in pancreatic cancer cell lines in vitro and in vivo. Methods: In vitro, to test synergic actions, cell viability and apoptosis were analyzed after treatment of pancreatic cancer cell lines with the two agents singly or in combination. The molecular mechanisms of apoptotic effects were also explored using qRT-PCR and Western blotting. In vivo, a tumor xenograft model was established in nude mice, for assessment of inhibitory effects of triptolide and artesunate. Results: We could show that the combination of triptolide and artesunate could inhibit pancreatic cancer cell line growth, and induce apoptosis, accompanied by expression of HSP 20 and HSP 27, indicating important roles in the synergic effects. Moreover, tumor growth was decreased with triptolide and artesunate synergy. Conclusion: Our result indicated that triptolide and artesunate in combination at low concentrations can exert synergistic anti-tumor effects in pancreatic cancer cells with potential clinical applications.

Objectives: This study was conducted to determine the heavy metal contents in commercial herbal medicines in Korea. Methods: Monitoring of lead, arsenic, cadmium and mercury was carried out on 116 samples of eleven types of herbal medicines. Among the total samples, 71 samples were domestic and 45 were imported. The samples were digested using the microwave method. The heavy metal contents were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) and a mercury analyzer. ICP-AES was used to analyze lead, arsenic cadmium. Mercury was analyzed by the amalgamation method. Results: The mean values of the heavy metal contents in the herbal medicines were Pb 0.64mg/kg, As 0.26mg/kg, Cd 0.07mg/kg and Hg 0.004mg/kg. Of the total samples, one violated the MFDS (Ministry of Food and Drug Safety) regulatory guidance on heavy metals in herbal medicines. Lead was detected at more than 5mg/kg in one sample. The measured values of arsenic, cadmium and mercury in the herbal medicines showed levels lower than the recommended levels for herbal medicines in MFDS regulatory guidance. In the comparison of domestic samples with imported herbal medicines, it was found that one domestic sample surpassed the maximum residue limits for lead. Conclusion: These results will be used to establish the regulation and control of heavy metal contents in herbal medicines.

Herbal medicine has a high body absorption rate when it ferments. Biological and clinical research on the fermented herb gradually increases because it has effective materials for the treatment of a disease and it is a little bitter. In this study, we investigated the effect of fermented Baedokhwanbalhyobang (BDHBH) on attenuation of the development of atopic dermatitis in NC/Nga mice by evaluating the cytokine level in serum, the mRNA expression of cytokine and histological alteration of the skin, and the skin severity. We have come to the following conclusion. BDHBH led to a significant decrease in the skin severity score (63.1%) as compared to the control group. CD4+/CD45+, CD4+, B220+/CD23+, and CD11b+/Gr-1+cells of peripheral mononuclear cells (PBMCs) in the BDHBH-treated group were decreased to 6.7%, 31.1%, 22.4%, 36.6%, respectively. CD3+and CD11b+/Gr-1+immune cells in dorsal skin of the BDHBH-treated group were decreased to 52.9% and 28.0%. The levels of IL-5 and IL-13 in serum of the BDHBH-treated group were inhibited to 18.8% and 5.1%. The mRNA expressions of IL-5 and IL-13 in dorsal skin were also decreased to 30.6% and 27.8% after the treatment of BDHBH. BDHBH inhibited the proliferation and differentiation of eosinophils. In histological examination, BDHBH decreased the thickness of epidermis and dermis, and infilatration of mast cells as compared to the control group. These results indicate that BDHBH inhibits the pathogenic development of atopic dermatitis in NC/Nga mice. These results may indicate that BDHBH attenuates the development of atopic dermatitis-like lesions by lowering immune cells and inflammatory cytokine levels, and that it is valuable in drug development for the treatment of atopic dermatitis. Further experiments on the components of BDHBH will be needed to better understand the effect of a fermented herb as compared to a herb.
