  • This study was designed to examine agro-healing services and programs provided and operated by farms in Korea. The results of the analysis of the agro-healing programs and operation of farms were as follows. The purpose of the operation of farms was to raise productivity by managing farms in a cooperative way through agricultural production, education and healing, and to raise income by processing and selling agricultural products. It was difficult to access farms by public transport and thus visitors had to use their own cars. The size of farms varied. The main resources utilized in the surveyed programs were plants, rural environments and landscapes, and agricultural products. The programs were conducted using resources that were commonly found in rural areas. Facilities on each farm were equipped with facilities (indoor and outdoor learning place, gardens, vegetable gardens, orchards, etc.) and convenience facilities (parking lots, drinking fountains, kiosks, etc.) to support program operation. However, facilities for the handicapped and accommodation facilities were insufficient. The programs operated on each farm utilized agricultural resources, farm produce, and rural resources and were classified into activities such as making, feeling, and growing. The average number of people who operated the family-centered program was 2-3, having qualifications such as welfare horticultural therapists, forest interpreters, experience instructors, and social workers. In addition, they had expertise in medicinal food, dietary life, and social welfare, and they also had essential expertise required to operate programs.

  • Background: The public has increasing concerns about herbal crops owing to insufficient information on biological hazards such as foodborne pathogens. Therefore, the objective of this study is the development of a herbal crop quality control system through monitoring with biological hazard analysis. Today, it is estimated that millions of people become ill every year from food contamination. The public demands agricultural products of stable and consistent quality. Governments have the responsibility of establishing the standards, legislation and enforcement programs necessary to control food quality and safety. However, research on the biosafety of herbal crop products is still insufficient. Therefore, the implementation of monitoring systems with high standards is critical for public safety. Methods and Results: In this study, we collected 52 samples of herbal crop products, and conducted both quantitative and qualitative biological hazard analysis. With biological hazard analysis, aerobic bacteria, Staphylococcus aureus, Salmonella spp., Escherichia coli, Coliforms, and Listeria spp. could be detected. Conclusions: Herbal crops were found to be contaminated with aerobic bacteria at $3.69{\pm}0.32log\;CFU/g$. Staphylococcus aureus, Salmonella spp., Escherichia coli, Coliforms, and Listeria spp. were not detected in any of the samples. This research suggests that continuous monitoring of biological hazards is required to improve the quality of herbal crops.

  • 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.

  • Objectives: This study aimed to ascertain what should be considered in the "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer" by analyzing the existing guidelines and clinical trials. Methods: The committee searched guidelines and clinical trials about herbal medicine for lung cancer. The searched trials were analyzed in terms of inclusion and exclusion of participants, intervention, comparator, outcomes and trial design. Then, we compared the results of our analysis with the guidelines to identify the issues we will have to consider when making the "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer". Several guidelines for anti-tumor agents and clinical trials with herbal medicine were searched on the national institution homepage. The search terms were as follows: 'lung neoplasm', 'herbal medicine', 'Medicine, Korean traditional', 'Medicine, Chinese Traditional' etc. Results: There was no guideline for clinical trial with herbal medicine for lung cancer. In addition, 7 articles were searched through database searching. All the participants had non-small cell lung cancer. The type of intervention was decoction. Comparators included conventional treatments such as chemotherapy. The outcome measurements used in the studies were quality of life, tumor response, and survival duration, etc. Safety was evaluated by recording adverse events and blood test. Conclusions: Findings were made by reviewing existing guidelines and comparing them with clinical trials for lung cancer and herbal medicinal products. These results will be utilized in the development of "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer".

  • Objectives : The purpose of this study is to find a reasonable solution to a current status of drug classification between the drugs of western conventional (allopathic) medicine and Korean medicine. A clear and distinct concept on the drugs of allopathic medicine and Korean medicine based on reasonable concepts and broad consensus is a pressing issue in Korea, and will facilitate the development of herbal medicinal products and pharmaceutical industry. Methods : Considering the issue of drug classification from domestic and international regulations, we reviewed the current Drug Law of Korea and China, Guidance for Industry, Botanical Drug Products of USA, Directive 2004/24/EC of the European parliament and of the council. Results : In Korea, the drug classification of allopathic medicine and Korean medicine is quite vague even though differential licensure system is enforced for the clinicians of allopathic medicine and Korean medicine field. According to the definition in the Drug Law, the scope of Korean medicine drug is so broad that even a drug made of single-compound material, as well as herbal extract of crude mixture, is regarded as a drug of Korean medicine, as long as the material may be separated from medicinal herbs, animal tissues, or mineral resources. Only new compound not found in natural resources are outside of the scope of Korean medicine drug. In USA and EU, medicinal products manufactured from herbs are approved by separate regulations for the herbs with special waivers. In China, the category of new medicine and the definition of allopathic medicine and traditional chinese medicine are clearly specified and classified. Conclusions : As medicines are validated therapeutic materials for efficacy and toxicity, we suggest that generally the concept of conventional medicines is based on a single compound that has been synthesized and individually validated and that of Korean medicines is based on a compound extracted from natural materials or a complex of compounds that has been validated as a whole in its totality.

  • A high performance liquid chromatographic (HPLC) method for the determination of glycyrrhizic acid was developed for the quality control of traditional herbal medicinal preparation Bu-Zhong-Yi-Qi-Tang (BZYQT), which is well-known herbal medicine used as tonic. RP-HPLC analysis was carried out using Capcell pak $C_{18}$ MG column $(5\;{\mu},\;150{\times}4.6\;mm)$ and a mobile phase consisting of acetonitrile and water containing 0.03% phosphoric acid (pH 2.46) at a flow rate of 1.0 ml/min. The optimum wavelength for the detection of the glycyrrhizic acid was found at 250 nm using diode-array UV/VIS detector. The glycyrrhizic acid in BZYQT shows good linearity $(r^2>0.999)$ in the range of $15\;{\mu}g/ml$ to 500 ${\mu}g/ml$. The limit of detection (LOD) was less than 5 ng and R.S.D for intra-day and inter-day reproducibility was less than 7%. The mean recovery of the glycyrrhizic acid was $97.3{\sim}113.0%$. These results suggest that the developed HPLC method is simple and efficient, and could be contributed for the quality control of commercial BZYQT products.

  • Dietary supplements are used by more than one-half of the adult US population. By contrast, herbal products in Germany are carefully regulated by the same standards as drugs, and efforts are under way to standardize their regulation in the entire European Union. Most herbal users do not inform their physicians that they are taking these supplements, and most physicians do not inquire. Although some herbal products have clinically proven benefits, it is increasingly apparent that many contain potentially toxic substances, particularly in relation to interactions with drugs. Hence, it is essential that practicing physicians develop a working knowledge of herbals-specifically, about claims for their usage and potential or proven efficacies and toxicities-and that they incorporate such knowledge into the evaluation and management of their patients. By contrast, functional foods-integral components of the diet that are understood to contribute added health benefits-are the subject of intense and widespread research in food and nutritional science. Examples include many polyphenolic substances, carotenoids, soy isoflavones, fish oils, and components of nuts that possess antioxidant and other properties that decrease the risk of vascular diseases and cancer. Practicing physicians are advised to stay abreast of these emerging findings in order to best advise their patients on the value of health-promoting diets in disease prevention.

  • Objectives : Since single extract powders was released at 1987, the insurance fee has not been changed, but the price of raw material has been increasing. According to this, Pharmaceutical company couldn't invest on quality of the product, so, the quality of single extracts went down and lost the consumer's trust. We checked the contents of marker ingredients in single extract thereby to recover the reliability of insurance-covered herbal preparations. Methods : we bought total twelve products of eight different single extracts of two main pharmaceutical companies among total 65 kinds of single extract powder stipulated in KHP (The Korean Herbal Pharmacopoeia) monograph III at Jan. 2013. Assays of selected single extract powders are performed by KHP regulation. And we surveyed price fluctuation of relevant herb raw materials from 2005 to 2012. Results : Among twelve products, eight single extract powders were suitable by the KHP regulation. But four products didn't reach the content amount of KHP. Marker contents in the single extracts product of Pueraria Root, Licorice, Peony root and Scutellaria Root of A company were 70%, 1%, 23.7% and 75.1%, respectively. Conclusions : We can acertain whether there's a quality problem in the insurance-covered single extract powders. But, A company is no longer producing these improper single extract powders. As a medicine, single extract powders needs to be strictly quality controlled by the company, and regularly monitored by the KFDA.
