Objective: Nowadays the combined use of herbal extracts and western medicines has been prevalent, but concern about its risk is also increasing. Even though the importance of clinical trials is well recognized, there have been only a few studies on the combined use of herbal extracts and western medicines. This study was aimed to examine which herbal extracts and antiplatelets or anticoagulants are most commonly prescribed together to inpatient ischemicstroke patients and investigate the combined prescription rate. Methods: We investigated the most frequently prescribed herbal extracts from two different sources. First, we chose herbal medicine extracts from 2008 Traditional Korean Medicine Utilization Status. Then, among patients who were admitted to Kyung-Hee Oriental Medical Center diagnosed with ischemic stroke, we found patients who were administered with these herbal medicine extracts and among these patients, we investigated how many were concomitantly administered with antiplatelets or anticoagulants. Second, we chose other herbal medicine extracts that were most often prescribed within Kyung-Hee Oriental Medical Center and found patients who were administered with these herbal medicine extracts, then investigated how many of them were concomitantly administered with specific antiplatelets or anticoagulants. Results: The most commonly prescribed herbal medicine extracts among ischemic stroke patients were Ojeok-san, Bojungikgi-tang, Sochungryong-tang and Samsoeum. About 46 to 69 percent were concomitantly administered with either specific antiplatelets or anticoagulants. Conclusions: The most often prescribed herbal medicine extracts in inpatient ischemic stroke patients are Ojeok-san, Bojungikgi-tang, Sochungryong-tang, and Samsoeum. Among patients who were prescribed with Ojeok-san, Bojungikgi-tang, Sochungryong-tang, Samsoeum, patients who were concomitantly administered with either antiplatelets or anticoagulants were about 46% to 69%.

The aim of this study was to investigate whether a novel formulation of an herbal extracts has an inhibitory effect on obesity. To determine its anti-obesity effects, we performed anti-obesity-related experiments in vitro and in vivo. Thus, our present study was carried out to evaluate the anti-obesity effect of herbal extracts using a high fat diet (HFD)-induced obese mouse model and 3T3-L1 adipose cells. The effects of each herbal extracts on lipid accumulation in 3T3-L1 cells were examined using Oil Red O staining. Results showed that treatment with each herbal extracts at $10{\sim}100{\mu}g/ml$ had no effect on cell morphology and viability. Without evidence of toxicity, herbal extracts treatment decreased lipid accumulation compared with the untreated adipocytes controls as shown by the lower absorbance of Oil Red O stain. Futhermore, compared with control-differentiated mature adipocytes, each herbal extracts significantly inhibited lipid accumulation in mature 3T3-L1 adipocytes. In the HFD-fed obese mice, body weight, liver weight and white adipose tissue weights were significantly reduced by mixture of herbal extracts administration in mouse skin. Futhermore, we found that mixture of herbal extracts administration suppressed serum triglyceride (TG), and total cholesterol (TCHO) in HFD-induced obese mouse model. The mixture of herbal extracts of permeability was estimated by measuring the transepithelial electrical resistance (TEER) value in pig skin. The optimized formulations of herbal extracts (Test 3 formulation) showed skin permeation. However, test 1 formulation containing essential oil as enhancer showed maximum skin permeation. After confirming the enhanced skin permeability, in vivo studies were performed to assess whether skin irritation potential on the basis of a primary irritation index (PII) in rabbit skin. Reactions were scored for erythema/edema reactions at 24 h, 48 h and 72 h post-application. It was concluded that the test 1 formulation was not irritation (PII = 0). The present study suggests that the test 1 formulation might be of therapeutic interest with respect to the treatment of obesity.

Various herbal medicinal extracts were examined for the development of cosmetic products with anti-oxidative and anti-wrinkle activity. First, total polyphenol contents and DPPH radical scavenging activities of herbal medicinal extracts were measured. Most herbal samples, except for DW extracts of Portulaca oleracea, Caesalpinia sappan, Taraxacum platycarpum, Carthamus tinctorius, and 70% EtOH extracts of Taraxacum platycarpum and Carthamus tinctorius, showed DPPH radical scavenging activity over 80% at a concentration of $400{\mu}g/m{\ell}$. SOD-like antioxidant activity of DW extracts of Syzygium aromaticum, DW extracts of Eriobtrya japonica and 70% EtOH extracts of Sophora japonica was measured as 40%, 35% and 80%, respectively at a dry matter concentration of $50{\mu}g/m{\ell}$. In elastase inhibition assay, DW extracts of Lycium chinense ($50{\mu}g/m{\ell}$) and 70% EtOH extracts of Areca catechu ($50{\mu}g/m{\ell}$) showed 50% and 40% of inhibition, respectively. At a concentration of $1.250{\mu}g/m{\ell}$, DW extracts of Lycium chinense and 70% EtOH extracts of Areca catechu showed 10% and 30% of collagenase inhibition, respectively. Skin and lotion samples were prepared using the two herbal extracts of high anti-wrinkle activity: Lycium chinense extract and Areca catechu extract. The storage stability of skin and lotion containing each of the selected herbal extracts was evaluated. pH and viscosity were used as stability indicators for the stability test under different storage temperatures and freeze-thaw cycle conditions. The skin and lotion containing each of DW extract of Lycium chinense and 70% EtOH extract of Areca catechu was showed high pH and viscosity stability. The skin and lotion containing DW extracts of Lycium chinense showed relatively higher stability than the skin and lotion containing 70% EtOH extract of Areca catechu, at cycle chamber and freeze-thaw conditions. In summary, these results indicated that cosmetics containing DW extract of Lycium chinense were relatively stable, and this herbal extract could be used as a stable functional cosmetic material.

Aster koraiensis Nakai (A. koraiensis) which has been used as a food and medicinal plant in the past, is valuable as functional food material. Therefore, the aim of this study was to determine the antioxidant properties and major phenolics of A. koraiensis extracts with different ethanol concentrations (0, 50, 70, and 100% aqueous ethanol solution). When ethanol concentration in the extraction solvent was increased, extraction yield decreased; 34.2, 23.2, 21.0, and 5.5% in 0, 50, 70, and 100% ethanolic extracts, respectively. Total phenolics content and antioxidant activities of extracts were increased in an ethanol concentration-dependant manner. The major phenolics in the extracts were chlorogenic acid (21.264~58.666 mg/g), isochlorogenic acid A (10.432~145.353 mg/g), and isochlorogenic acid C(0.239~13.148 mg/g), and these phenolic contents were higher in 70 and 100% ethanolic extracts than other extracts. Significant correlations were observed between ethanol concentration of extraction solvent, antioxidant properties, and major phenolics. These results indicated that the optimal ethanol concentration for extraction was 70%.

Ganoderma lucidum, an oriental polypore fungus and medicinal mushroom, has a long history of use for promoting health and longevity in Korea, China, and other Asian countries. This study was aimed at determining the anti-inflammatory activity and mechanism of action of Ganoderma lucidum in murine macrophage RAW 264.7 cells. Ganoderma lucidum was extracted with ethanol and freeze-dried. The anti-inflammatory effect (nitrite production) of Ganoderma lucidum extracts was tested using a nitric oxide (NO) colorimetric assay. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was performed to quantify the mRNA expression of cytokines including tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$), interleukin $(IL)-1{\beta}$, and IL-6. Western blotting was performed to measure the expression levels of inflammation-related proteins, such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor kappa B ($NF-{\kappa}B$) p65, and phosphorylated $NF-{\kappa}B$ p65. The NO colorimetric assay showed that NO production increased with the treatment of lipopolysaccharide in (LPS)-activated RAW 264.7 macrophages and decreased with the cotreatment of Ganoderma lucidum extracts and LPS. Ganoderma lucidum extracts repressed the mRNA expressions of cytokines, which were increased after the LPS treatment. In addition, Ganoderma lucidum extracts inhibited the LPS-induced expression of iNOS and COX-2 and the LPS-induced phosphorylation of $NF-{\kappa}B$ p65. These results suggest that the Ganoderma lucidum extracts exert an anti-inflammatory activity by inhibiting $NF-{\kappa}B$ related proteins and cytokines.
