Many skin diseases are caused by microbial infections. Representative pathogenic fungus and bacterium that cause skin diseases are Candida albicans and Staphylococcus aureus, respectively. Malassezia pachydermatis is a fungus that causes animal skin diseases. In this study, we propose a method for removing pathogenic microorganisms from the skin using relatively safe edible herbal extracts. Herbal extracts were screened for skin health through the removal of pathogenic microorganisms, and combinations for effective utilization of the screened extracts were identified. In this study, among methanol extracts of 240 edible plants, C. albicans, S. aureus, and M. pachydermatis were killed by extracts of 10 plants: Acori Gramineri Rhizoma, Angelicae Tenuissimae Radix, Cinnamomi Cortex, Cinnamomi Ramulus, Impatientis Semen, Magnoliae Cortex, Moutan Cortex Radicis, Phellodendri Cortex, Scutellariae Radix, and Syzygii Flos. By evaluating the synergistic antifungal activities against C. albicans using all 45 possible combinations of these 10 extracts, five new synergistic antifungal combinations, Acori Gramineri Rhizoma with Magnoliae Cortex extracts, Acori Gramineri Rhizoma with Phellodendri Cortex extracts, Angelicae Tenuissimae Radix with Magnoliae Cortex extracts, Magnoliae Cortex with Phellodendri Cortex extracts, and Phellodendri Cortex with Syzygii Flos extracts, were identified. By utilizing the selected extracts and five combinations with synergistic antifungal effects, this work provides materials and methods to develop new and safe methods for treating candidiasis using natural products.

Oriental herbal medicines were examined for mutagenicity in the reverse mutation test on Salmonella typimurium T A98/100 and chromosomal aberration test on cultured mammalian cells (Chinese hamster cell lines). The reverse mutation test was performed by a plate incorporation method with and without a metabolic activation system (S9 mix). The tested herbal medicines did not significantly increase revertible colonies on any of the test strains with and without a metabolic activation system (S9 mix) at concentrations of 1 mg/ml. In the chromosomal aberration test, most tested herbal medicines did not significantly increase the number of aberrant cells on any of the test strains with a metabolic activation system (S9 mix) at concentrations of 1 mg/ml, compared with the vehicle control. However. Ansu Semen significantly increased the number of aberrant cells without a metabolic activation system (S9 mix). Paeoniae Radix. Hoelen, Aurantii nobilis Pericarpium, Cnidii Rhizoma, Angeliacae gigantis Radix, Perillae Herba and Moutan Cortex Radicis slightly increased revertible colonies on any of the test strains with a metabolic activation system (S9 mix), These results indicate that most herbal medicines might be carefully used in obstetrics and gynecology, although they do not have the potent mutagenic potential under the present test conditions.

Vascular inflammation is an important event in the development of vascular diseases such as tumor progression and atherosclerosis. This study was to investigate the inhibitory effects of WK-38, a new herbal prescription for the treatment of atherosclerosis, on vascular inflammation in human umbilical vein endothelial cells (HUVEC). WK-38 is composed of Rhei Rhizoma, Magonoliae Cortex, Moutan Cortez Radicis. Pretreatment with WK-38 was significantly blocked TNF-$\alpha$-induced expression level of cell adhesion molecules such as vascular cell adhesion molecule-1 (VCAM-1), intracellular adhesion molecule-1 (ICAM-1), and endothelial cell selectin (E-selectin) in a dose-dependent manner. TNF-$\alpha$-induced cell adhesion in co-cultured U937 and HUVEC was also blocked by pretreatment with WK-38. Moreover, WK-38 significantly suppressed p65 NF-${\kappa}B$ translocation into the nucleus by TNF-$\alpha$ as well as the phosphorylation and degradation of $I{\kappa}B-{\alpha}$. In conclusion, the present data suggested that WK-38 could suppress TNF-$\alpha$-induced vascular inflammatory process, though inhibition of NF-${\kappa}B$ activation in HUVEC.
