Artemisia is a major edible vegetable in Korea and it has traditionally been used as a herbal medicine for the treatment of coughing, abdominal pain, indigestion, bleeding, jaundice, chronic liver disease and diabetes. However the biological and pharmacological actions of the herb have not been studied well. Recently it is known to possess antibacterial, antihelmintic and antifertility activities. But the effect of Artemisia capillaris extract on carbon tetrachloride($CCl_4$) induced liver damage in dogs have not been reported yet. This study was designed to investigate the effect .of Artemisia capillaris crude juice extract on $CCl_4$ induced liver damage in dogs. 30 clinically healthy dogs were divided into 2 groups: crude Artemisia capillaris juice treated group(CEC group) and carbon tetrachloride($CCl_4$) administerd group. The results are as follows: I. The degree of increase in AST activity and ALT activity in CEC group was lower than that in $CCl_4$ group and the recovery in CEC group was faster than that in $CCl_4$ group. 2. Changes of ALP concentration in CEC group were significant(P < 0.05) but changes of Total-bilirubin concentration were not significant(P < 0.05) in both groups. 3. The recovery of GGT concentration in CEC group was faster than that in $CCl_4$ group. 4. Hematological changes other than MCHC were significant(P < 0.05) in CEC group only and changes of GSH and Met-Hb concentration were significant(P < 0.05) in $CCl_4$ group.

Artemisia capillaris has been widely used as an alternative therapy for treating obesity and atopic dermatitis. It has been used as a hepatoprotactant. It is also used for ameliorating inflammatory reactions. Although there are several investigations on other Artemisia species, there is no systematic study describing the role of A. capillaris MeOH extract, its solvent soluble fractions, or derived anti-inflammatory principal components in regulating inflammatory conditions. Therefore, the objective of this study was to elucidate anti-inflammatory mechanisms of A. capillaris. Results revealed that MeOH extract of A. capillaris could decrease LPS-stimulated NO secretion. Of tested fractions, $CH_2Cl_2$, EtOAc, and n-BuOH strongly inhibited NO release from RAW264.7 cells. Bioactive mediators derived from $CH_2Cl_2$ and n-BuOH fractions elicited potent anti-inflammatory actions and strikingly abrogated LPS-triggered NO accumulation in RAW264.7 cells. Of particular interest, capillin and isoscopoletin possessed the most potent NO suppressive effects. Western blot analysis validated the molecular mechanism of NO inhibition and showed that capillin and isoscopoletin significantly down-regulated iNOS and COX-2 protein expression. Taken together, our results provide the first evidence that MeOH extract, $CH_2Cl_2$, EtOAc, and n-BuOH fractions from A. capillaris and its derived lead candidates can potently suppress inflammatory responses in macrophages by hampering NO release and down-regulating iNOS and COX-2 signaling.

This study extracted Artemisia capillaris Thunberg with distilled water and ethanol to investigate its antioxidant effect. We then investigated the possibility of producing nanofibers by an electrospinning process by adding the extracts to polyvinyl alcohol (PVA). The electrospinning method used a PVA concentration of 12wt.%, an applied voltage of 10kV, and a tip-to-collector distance of 15cm. Total polyphenol and total flavonoid contents were measured to verify the antioxidant activity of Artemisia capillaris Thunberg extracts (ACEs). The total polyphenol content of the distilled water extract and the ethanol extract were measured as 218.47 and 271.26mg/g, respectively, and the total flavonoid content of the distilled water extract and the ethanol extract were measured as 141.68 and 34.98mg/g, respectively. As the content of the ACEs in the PVA nanofibers increased, the Diameters of the nanofibers and the uniformity of the diameters decreased. The electrospinning process was fabricated in a relatively uniform form without beads, and the diameters of the nanofibers that were produced ranged from 340 to 390nm. The results of FT-IR, XRD and DSC analyses confirmed that the ACEs were well mixed with the PVA molecules and were electrospun.

Artemisia capillaris (A. capillaries) is known to play roles in many cellular events, such as cell proliferation, differentiation, and apoptosis. We investigated the antifibrogenic efficacy of A. capillaris in the immortalized human hepatic stellate cell line LX2. Cell proliferation was determined by the MTT assay. Cell cycle was analyzed by the flow cytometry. Apoptotic cells were measured using a cell death detection ELISA. Caspase activity was detected by a colorimetric assay. The mRNA level of Bcl-2 and Bax mRNA were measured by real-time PCR. MEK and ERK protein were detected by Western blot analysis. We provide evidence that A. capillaris induces cell cycle arrest, apoptosis, and potently inhibits the mitogen-activated protein kinase pathway. A. capillaris inhibited cell proliferation of LX2 cells in a dose- and time-dependent manner, increased the apoptosis fraction at cell cycle analysis with an accompanying DNA fragmentation, and resulted in a significant decrease in Bcl-2 mRNA levels and an increase in Bax expression. Exposure of LX2 cells to A. capillaris induced caspase-3 activation, but co-treatment of A. capillaris with the pan-caspase inhibitor Z-VAD-FMK, and the caspase-3 inhibitor Z-DEVE-FMK, blocked apoptosis. A. capillaris down-regulated Mcl-1 protein levels and inhibited phosphorylation of MEK/ERK, suggesting that it mediates cell death in LX2 cells through the down-regulation of Mcl-1 protein via a MEK/ERK-independent pathway.

Background: Many herbal medications have been used to treat various liver diseases. But the concerns of herbal medicine induced liver injury also existed. In this respect, we would like to report several cases with imporved elevated liver aminotransferase after treating herbal medicine including Artemisia capillaris. Case Reports: We report four patients with elevated aminotransferase levels (ATLs), which indicate hepatocellular damages. After receiving herbal medicines therapy containing Artemisia capillaris as principal component (HMA), the patients' ATLs were improved. In the first case, the patient's ATLs decreased into normal range after administration of HMA, although they have not been improved with hepatotonics for a long period. In the second case, the patient's ATLs have been elevated after taking anticoagulants. The ATLs were improved with HMA without stopping anticoagulants. In the other two cases, the patients' ATLs were also improved after taking HMA. In addition, there were no changes of previous drugs for treating the corresponding underlying diseases and no adverse events during HMA applications. Result and Conclusion: The four patients received the herbal medicine containing Artemisia capillaris as principal component and showed improvement of ATLs. These cases suggest that HMA can be considered as alternative or complementary remedies to improve various liver diseases.
