Objectives: This study aimed to review clinical and experimental studies using Korean traditional herbal medicine for dementia on the improvement of cognitive function and changes in gut microbiota. Methods: We searched 12 databases for clinical and experimental studies on the effect of Korean traditional herbal medicine treatment for dementia on changes in gut microbiota. Sample sizes, dementia types, diagnosis criteria, interventions, outcomes, and results, including changes in gut microbiota, were extracted from the included clinical studies and analyzed. Subjects, interventions, outcomes, and results, including gut microbiota changes, were extracted from the included experimental studies and analyzed. Results: A total of 22 studies were selected, and most of them were experimental studies. Improvement in cognitive function and changes in gut microbiota were reported in all studies. The most frequently used herbal material was Poria cocos, and the most frequently used prescription was Danggwijagyak-san and Chilseong-hwan. Lactobacillus, Firmicutes, Bacteroidetes, and Proteobacteria were frequently assessed gut microbiota. Conclusions: These results suggest the treatment potential of Korean traditional herbal medicine for dementia by regulating gut microbiota. However, there were discrepancies related to changes in gut microbiota among studies. Therefore, further studies are needed to clarify the effect and mechanism of Korean traditional herbal medicine for dementia on gut microbiota.

Herbal plants or traditional Oriental medicine have been considered as a potential resource of new drug development worldwide. However, traditional Korean medicine has given little effort to the field of new drug development. This study reports on a plant-derived hepatotherapeutic drug, silymarin, which has been popularly used in many countries. It was discovered as an active compound from Silybum marianum (milk thistle) which has been known as a medicinal plant having hepatoprotective properties in both European and Asian countries. While it has been used as an herbal prescription in Asia, its active compounds or scientific mechanisms were intensively studied in Europe. Currently, silymarin is one of the most powerful herbal extracts in the world, and its usage is being expanded to many other medical purposes. This report would be helpful for providing an informative example of herbal-derived drug development to Oriental doctors or scientists in the Oriental medicinal field.

We performed this study to determine the radioprotective effects of Shi-Quan-Dai-Bu-Tang, as a prescription of traditional Oriental medicine, and its major ingredients. The jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were investigated in mice irradiated with high and low dose of ${\gamma}$-rays. The administration of danggui, baishaoyao, rensan, gancao or baifuling before irradiation protected the jejunal crypts (p<0.005). Shoudehuang, danggui, baishaoyao, rensan and huangqui increased the formation of endogenous spleen colony (p<0.05). Chuanxiong, baishaoyao, rensan and baifuling reduced the frequency of radiation-induced apotosis (p<0.05). The results indicated that the extracts of danggui, baishaoyao, rensan and baifuling may have radoprotective effects in mice irradiated with high and low dose of ${\gamma}$-rays. The radioprotective effect of the prescription, Shi-Qaun-Da-Bu-Tang, was not significant.

In order to search for protein tyrosine phosphatase 1B (PTP1B) inhibitors as therapy of type 2 diabetes and obesity from Korean traditional prescriptions, we selected 58 traditional prescriptions based on a review of the Korean traditional medicine books. The hot water extracts of Korean traditional prescriptions were screened for the inhibitory activity against PTP1B. Among the tested extracts, water extracts of Jakgamhwangsinbu-tang, Seonbanghwalmyung-eum, and Takreeonjoong-tang showed relatively good inhibitory activity against PTP1B at the concentration of $30{\mu}g/ml$. Additionally, we evaluated PTP1B inhibitory effect for each herbal ingredient and composition in Jakgamhwangsinbu-tang (芍甘黃辛附湯). Of the tested ingredients from this herbal medicine, water extracts of Paeoniae Radix rubra and Rhei Rhizoma, and ethanol extracts of Paeoniae Radix alba, Rhei Rhizoma, Asiasari Radix, and Aconiti Tuber showed good PTP1B inhibitory effect. Herbal compositions composed of these active herbal ingredients exhibited significant activity for PTP1B inhibition over 70% at $7.5{\mu}g/ml$.

We have examined in vitro and in vivo radioprotective effect of a Chinese medicinal plants prescription, Lifukang. Micronucleus assay was employed to evaluate in vitro radioprotective effect of Lifukang. In the presence of Lifukang, the frequencies of miconuclei were greatly reduced from 7.2 to 2.9, 1.6 and 1.6% at the concentrations of Lifukang from 0 to 2, 10 and $50{\mu}g/ml$, respectively. For in vivo assay, we monitored the incidences of apoptotic cells in mouse small intestine crypts and endogeneous spleen colonies. When Lifukang was administered to mice P.O. Or I.P. at doses of 1 mg/ml in drinking water for 7 days or 0.3 mg/mouse 24 hrs prior to irradiations, respectively, the average numbers of apoptotic cells were reduced to 3.1 or 2.3, respectively, as compared to 4.4 acquired from untreated control experiments. In addition, in spleen colony assay, Lifukang increased the number of hematopoietic spleen colonies. When samples were administered after irradiation, better results were obtained. The numbers of spleen colonies were increased from 14 colonies to 18.3 or 19.6 colonies when Lifukang was given through P.O. (1 mg/ml in drinking water for 11 days) or I.P. (0.3 mg/ mouse) after irradiation, respectively.

Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

Sihosamultang(SST) has been used for the treatment of puerperal fever, liver disease in traditional medicine. The present study was carried out to evaluate the antioxidant effects of SST extract in vitro. The inhibitory effect of SST extract on lipid peroxidant was examined in the linoleic acid autoxidation system. In this test, SST extract significantly inhibited the time course of the lipid peroxidation. And SST extract showed about 73% scavenging effect on DPPH radical. And this extract inhibited not only the lipid peroxide formation induced by hydroxyl radical derived from $ H_{2}O_{2}-Fe^{2+}$ in the rat liver homogenate, but also the superoxide generation from xanthine-xanthine oxidase system in a dose-dependent manner. In addition, SST extract protected the hepatic cell death induced by tert-butyl hydroperoxide. These data indicated that SST might play a protective role against oxidative injury by free radicals.
