Effects of Herbal Extracts on the Inflammatory Reactions

This study was carried out to investigate the effects herbal extracts on the skin inflammatory reactions. Among the herbal ingredients of herbal extracts, ethanol extract of Glycyrrhizae Radix showed potent radical scavenging activity, more than 86$\%$ at a concentration of 0.01$\%$, tested by DPPH(I,1-diphenyl-2-picryl-hyrazyl) method. And ethanol extract of Aurantii Immaturus Fructus inhibited the lipopolysaccharide-induced release of nitric oxide(NO), 99$\%$ at 50㎍／㎖, by the macrophage RAW 246.7 cells. In addition, the ethanol extracts of Sophorae Radix, Glycyrrhizae Radix showed antibacterial activities on Propionibacterium acnes that causes acne, Sophorae Radix, Glycyrrhizae Radix and Aurantii Immaturus Fructus on Corynebacterium xerosis that cause osmidrosis axillae, Glycyrrhizae Radix and Aurantii Immaturus Fructus on Staphylococcus aureus that was reported to cause impetigo and atopic disease. Taken together, I expect that herbal extracts may be used as a drug for treatment on skin inflammation.
