  • Herbal medicines have been used since ancient times as medicines to treat and relieve the symptoms of many different human diseases. However, so far, relatively few herbal medicines have been evaluated scientifically to prove their safety, potential benefits and effectiveness. This study was conducted to provide the groundwork for improving the current registration regulations for herbal medicines in distinction from synthetic medicines. The study was performed based on the literature research and individual interviews with 5 experts who had extensive experience in registration of herbal medicines. When compared with synthetic drugs, herbal medicines exhibit some marked differences, namely the active principles are frequently unknown, standardization, stability and quality control are not easy, they are usually mixtures of complex compounds. Second, the current regulations for herbal medicines are reviewed by comparison of foreign regulation systems like the one in China. The regulation requirements of herbal medicine in China are in distinction from synthetic drugs. The authors conclude that new registration requirements for the herbal medicines should be changed as follows; the toxicity and efficacy data should be submitted as mixed herbal preparation and the documents and other research on the reproduction and generation toxicity need to be shown for the proof of reproduction and generation toxicity, if needed.

  • Objectives: This study aimed to systematically review the effectiveness and safety of traditional herbal medicine treatments for metabolic syndrome (MS) in patients receiving antipsychotic drugs (APs). Methods: We searched 11 domestic and foreign databases for randomized controlled trials (RCTs) using traditional herbal medicines for MS in patients receiving APs. Results: Twenty RCTs conducted in China were included in the analysis. The most common disease among the participants was schizophrenia. Most studies used the 2004 Chinese Diabetes Society (CDS) standards as the diagnostic criteria for MS. The most used prescription was Yukultang (Liuyu-tang). The most used herbal material was Pinelliae Rhizoma, followed by Poria, Citri Reticulatae Pericarpium, and Glycyrrhizae Radix et Rhizoma. Traditional herbal medicines were mostly reported to improve the symptoms of MS. Conclusions: Traditional herbal medicines may be effective in improving the symptoms of MS in patients receiving APs. However, the quality of the included studies was low, and the studies were heterogeneous. Methodologically rigorous clinical studies on traditional herbal medicine treatments for MS in patients receiving APs are needed.

  • P-glycoprotein (P-gp) is a permeability glycoprotein also known as multidrug resistance protein 1 (MDR1). P-gp is an ATP-binding cassette (ABC) transporter that pumps various types of drugs out of cells. These transporters reduce the intracellular concentrations of drugs and disturb drug absorption. The Caco-2 cell permeability assay system is an effective in vitro system that predicts the intestinal absorption of drugs and the functions of enzymes and transporters. Rhodamine-123 (R-123) and digoxin are well-known P-gp substrates that have been used to determine the function of P-gp. Efflux of P-gp substrates by P-gp has been routinely evaluated. To date, a number of herbal medicines have been tested with Caco-2 cell permeability assay system to assess bioavailability. There are growing efforts to find phytochemicals that potentially regulate P-gp function. The Caco-2 cell permeability assay system is a primary strategy to search for candidates of P-gp inhibitors. In this mini review, we have summarized the P-gp modulation by herbal extracts, decoctions or single components from natural products using Caco-2 cell permeability assays. Many natural products are known to regulate P-gp and herbal medicines could be used in combination with conventional drugs to enhance bioavailability.

  • In order to unravel the implication on the Hwang Jahu's, a well-known medical doctor, critique of "HyangYakJibSungBang(鄕藥集成方)"(Compendium of Prescriptions from the Countryside)'s publication, this essay calls for an investigation of socio-economical situations and systematic support for the development of native herbal drugs of that time. In the period of King SeJong various systematic aspects supporting the development and utilization of native herbal drugs were created. In this ambient, Hwang Jahu also dedicated his life in the application of native herbal drugs. Though Hwang strongly recommended the use of native herbal herbs while importing insufficient resources from China. He gave a critique of "HyangYakJibSungBang(鄕藥集成方)"'s publication. Hwang's critique didn't lie on the book itself but on the practicality of this large volume from the public. He insisted more on the necessities of practical and easy accessible books for emergency situations. Throughout the emphasis on wide distribution of compact medical books and the utilization of acupuncture and moxibustion, in part reveals his pragmatic stand.

  • Herbal medicine, a multi-component treatment, has been extensively practiced for treating various symptoms and diseases. However, its molecular mechanism of action on the human body is unknown, which impedes the development and application of herbal medicine. To address this, recent studies are increasingly adopting systems pharmacology, which interprets pharmacological effects of drugs from consequences of the interaction networks that drugs might have. Most conventional network-based approaches collect associations of herb-compound, compound-target, and target-disease from individual databases, respectively, and construct an integrated network of herb-compound-target-disease to study the complex mechanisms underlying herbal treatment. More recently, rapid advances in high-throughput omics technology have led numerous studies to exploring gene expression profiles induced by herbal treatments to elicit information on direct associations between herbs and genes at the genome-wide scale. In this review, we summarize key databases and computational methods utilized in systems pharmacology for studying herbal medicine. We also highlight recent studies that identify modes of action or novel indications of herbal medicine by harnessing drug-induced transcriptome data.

  • Objectives: Dementia is a disease in which a person maintains a normal intellectual level during the growth period, but has acquired cognitive impairment and personality change. In this study, we tried to check whether the network pharmacology analysis method is useful in the search for herbal medicine resources for the treatment of dementia. Methods: The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database is a database frequently used in Chinese medicine research. We used the TCMSP to identify herbal medicines and their molecular targets that can be used for dementia by using network pharmacology research methods. Results: It was possible to select 28 types of components that are expected to be active by applying them to the living body, and 75 types of targets that these components act on were secured. In addition, 16 kinds of drugs were identified by checking the drugs containing 28 kinds of ingredients, and it was found that Radix Salviae contained 2 kinds of the selected 28 kinds of ingredients. Conclusions: Through this study, we were able to identify ingredients, drugs, and targets that can be used for basic and clinical research on dementia.
