Objectives : To direct methods of management and development of herbs and their derived products, and at the end of this study to inform the process of making new herbal drug regulations in Korea. Methods : This study analyzed the regulations and laws of western medicine drugs. Results : We have got some herbal prescriptions which are not in the eleven books of oriental medicine now in use but which have proved effective. We need to establish standards for permissions to produce medical products through those prescriptions. Besides, we need the special permissions to produce herbal products through prescriptions, especially those which have been used to treat incurable diseases. And, we can contribute to globalization of oriental medicine and to well situating of herb products and medicinal acupunctures if we produce them according to international standards. It is thought that herbal medicine has no side effect in the medical society in Korea. But, it is getting popular to administer herbal medicine and western medicine together. Thus, the side effects of taking both medicines at the same time should be documented. Conclusions : Herbal medicines and herbal products should be under the control over the whole process of production, circulation, and sales. Now, it is time for herbal medicine to be known to all over the world. Therefore, herbal medicine must meet and adhere to the standards set by the western society and WHO.

Objective : Many patients take antihypertensive drugs as well as herbal medicines at the same time in order to treat other symptoms or to keep their well-being. In this study, interactions between herbal medicines and synthetic antihypertensive drugs were analyzed. Methods : To investigate the interaction between herbal medicines and synthetic antihypertensive drugs, three electronic databases, including OASIS, Mediline and Sciencedirect were searched. Experimental and clinical studies on the interaction between herbal medicines and antihypertensive drugs were independently reviewed and included. Results : Analyzing selected studies, twenty herbs were found to interact with antihypertensive drugs. Herbs found to increase the antihypertensive effect were Panax ginseng, Carthamus tinctorius, Magnolia officinalis, Silybum marianum, Scutellaria baicalensis, Schisandra chinensis, Sophora flavescens, Piper nigrum, Curcuma longa, Ginkgo biloba, Juncus effuses and Hydrastis canadensis. In contrast, Commiphora myrrha, Rhodiola rosea, Hypericum perforatum, Eurycoma longifolia, and Daturae metel were found to inhibit the antihypertensive effect. Stephania tetrandra could increase or decrease the effect depending on the type of antihypertensive drug. Epedria sínica was suspected of pharmacodynamic interaction with antihypertensive drug. Glycyrrhiza uralensis has been reported to have serious side effects in combination with antihypertensive drugs. Conclusion : These results imply that when used in combination with herbal medicines and synthetic antihypertensive drugs, proper doses and herbs which are to avoid need to be informed to the patients. Despite concerns about interactions between herbal medicines and synthetic drugs, related research is very limited. More systematic researches are needed to give information on patient safety as well as to guide clinical practice.

Objectives Banha-sasim-tang (BST), which consists of seven different herbs, is one of the most popular herbal formulae for treating gastrointestinal disorders in Eastern Asia. The commonly used herbal medicine is often co-administered with other therapeutic drugs, which raises the possibility of herb-drug interactions and may modify the clinical safety profile of therapeutic drugs. Methods We investigated the potential herb-drug interactions between BST extract and midazolam (MDZ) in mice. The area under the plasma concentration-time curve (AUC) of MDZ and 1'-hydroxymidazolam (1'-OH-MDZ) was evaluated for both oral and intraperitoneal administration of MDZ, following oral administration of BST (0.5 and 1 g/kg). Results It was found that the AUC of MDZ and 1'-OH-MDZ was lower in case of oral administration of MDZ. Administration of BST extract was not associated with hepatic cytochrome P450 activity. BST extract induced a strong reduction in pH and it has been reported that oral mucosal absorption of MDZ is lower at low pH. The decreased absorption rate of MDZ might be caused by the ingredients of BST and may not be related to other factors such as increased excretion of MDZ by P-glycoprotein. Conclusions The altered pharmacokinetics of midazolam caused by co-administration with BST in vivo could be attributed to a decrease in pH and subsequent reduction of MDZ absorption rate.

Objective : Herb-drug interactions have become an important issue because of the consumption of herbal remedies has increased in the world. Yangguksanhaw-tang (Liang ge san huo-tang) and Taeumjowi-tang (Tai yin tiao wei-tang) are typical herbal formulas on Sasang constitution medicine (four-constitution medicine). This study was aimed at evaluating the effects of Yangguksanhaw-tang and Taeumjowi-tang on drug metabolizing enzymes, cytochrome P450 (CYP450) isozymes. Methods : Vivid$^{(R)}$ CYP450 Screening Kits were used to measure of CYP3A4, CYP2C19, CYP2D6 and CYP2E1 activities. This method is based on the use of fluorescent CYP450 substrates that are efficiently metabolized by specific CYP450 isozymes to yield a product with altered fluorescent properties. The percent inhibitions of CYP450s by herbal formulas were calculated. Results : Yangguksanhaw-tang inhibited CYP2C19 and CYP2E1 activities higher than that other CYP450 isozymes. The $IC_{50}$ values of CYP2C19 and CYP2E1 were 159.83 ${\mu}g/mL$ and 261.40 ${\mu}g/mL$, respectively. The CYP2E1 activity was inhibited ($IC_{50}=215.17{\mu}g/mL$) higher than that other CYP450 isozymes by Taeumjowi-tang. Conclusions : These results suggest that Yangguksanhaw-tang may inhibit the metabolism of co-administered drugs whose primary route of metabolism is via CYP2C19 or CYP2E1. Taeumjowi-tang could inhibit the metabolism of co-administered drugs, which are substrates for CYP2E1. Therefore, co-administration of the herbal formulas and other conventional drugs should be undertaken with care.

In vitro sensitivity testing was performed for 21 kinds putative anticancer drugs selected from references and information. Cellular damage of P815 mastocytoma cells following exposure to water extracts of drugs was evaluated by colony formation assay. Highly effective drugs with more than 50% inhibition of colony formation were seven (Houttuyniae Herba, Sanguisorbae Radix, Nepetae Herba, Manitis Squama, Lonicerae Flos, Amomi Semen, Polyporus), though not more effective than BCNU. According to the results of $^3H-thymidine$ incorporation assay for determination of selective cytotoxicity, 3 of these drugs (Houttuyniae Herba, Polyporus, Manitis Squama) were found to be low cytotoxic to normal mouse lymphoid cells. These findings suggest that the above 3 drugs may be used for effective anticancer drugs in vivo.

Sokmyeungtang was the representative prescription for Apoplexy under the rule of Tang and Song dynasty of which the cultures were thriving in the history of China. However, the clinical use of Sokmyeungtang has been gradually reduced since Geumwon dynasty of China because it was misunderstood that the dryness heat drugs of pungent in flavor and warm in property such as Ephedra, Pubescent Angelica Root, Chinese Cassia Tree-Bark, Divaricate Saposhnikovia Root, Prepared Aconite Root, Fresh Ginger, and Wildginger Herb included in the presciption for Apoplexy supplemented heat as damaging Yin flood. In fact, the drugs pungent in flavor and warm in property activate exterior and interior circulation, circulate channels and collaterals, promote blood circulation, and remove blood stasis with the side effect of relieving exterior syndrome with drugs warming channels. When treating Apoplexy with Sokmyeungtang, the cold drugs such as Gypsum, Baikai Skullcap Root, and Pueraria Root are prescribed to suppress fire of pungent dryness and to control excessive heat of people with Apoplexy as reducing the effects of hot drugs causing impairment of Yin. For treatment of Apoplexy, the above drugs accelerate blood and Qi circulation in channels and collaterals and then in necrotic tissue of human body as removing blood stasis. Consequently, these drugs improve disorders of capillary tube circulation. If Sokmyeungtang, an old prescription, is properly understood, it will be substantially helpful to all kinds of treatments in clinical cases
