  • It is important to establish the safety of herbal medicine because of its frequent and widespread use in Korea. Several studies on the safety of herbal medicine have been performed and there have been rare serious adverse drug reactions from those reports in Korea. However, the results are not strongly supported because of not adopting appropriate enough research methodology as to make the safety issue clear. For improving the quality of the safety research on herbal medicine. including investigations of drug induced liver injury (DILl). the aim of this study was to suggest herbal medicine-induced liver injury investigation forms for performing reasonable safety research. After a systematic review of the preceding studies regarding herbal safety in Korea was performed in 2008, we assessed the quality and the limitations of the primary studies. Two investigation forms for herbal safety research were made as a following step. one a basic investigation form for herbal safety research and the other an advanced investigation form for suspected DILl cases, Those forms include the essential informations and data needed to make an appropriate assessment of whether DILl occurred during or after the use of herbal medicine. Guidelines for using those forms and other recommendations were also suggested. More rigorous studies are required for answering the safety issue of herbal medicine as well as the efficacy issue. We hope for wide use and improvement of those investigation forms in the study of herbal safety by many researchers for establishing better evidences in Korea.

  • Objectives : To provide the information of preservation method for herbal decoction, we evaluated the anti-inflammatory effects according to preservation temperature and period of Pyungwi-san (PWS, Ping wei-san) decoction. Methods : The anti-inflammatory activity of PWS was investigated by carrageenin-induced paw edema in SD rats. At 0 month, PWS extract was administrated 100, 300 and 1000 mg/kg/day orally for seven days prior to induction of edema. Edema was induced by subcutaneous injection of 1% carrageenin into the right hind paw. The paw volume was measured at 4 hr following carrageenin-induced paw edema in rats. At 6 and 12 months, PWS extracts according to preservation temperatures (room temperature, $4^{\circ}C$ and $-20^{\circ}C$) were administrated in rats and then carrageenin-induced paw edema volume was measured. Results : PWS showed inhibitory effect on carrageenin-induced paw edema in rats and the optimal dose was 1000 mg/kg/day at 0 month of storage. At 6 month of storage, PWS storaged at $4^{\circ}C$ and $-20^{\circ}C$ were inhibited paw edema but that storaged at room temperature was not reduced paw edema in rats. Conclusions : These results suggest that PWS decoction pouch has anti-inflammatory activities at both $4^{\circ}C$ and $-20^{\circ}C$ during 6 month storage.

  • Objectives: To research Korean oriental medical doctors' use of uninsured herbal extracts and how to bring about the insurance coverage of such herbal extracts. Methods: We surveyed Korean oriental doctors about the following issues from October 17th to November 15th, 2008: (1) Korean oriental medical doctors' knowledge about herbal extract insurance and the circumstances of oriental medicine in Korea, (2) their opinion on the coverage of currently uninsured herbal extracts and the dispensing of herbal extracts from pharmacies rather than from their clinics, (3) their use of herbal extracts, and (4) how to bring about insurance coverage of uninsured herbal extracts. Results: Over 70% of the respondents said that herbal medicine prescriptions have been reduced recently and that the existence of herbal medicine is in danger. In addition, 63.64% respondents agreed with expanding insurance coverage to include currently uninsured herbal extracts in spite of the fact that patients might have to obtain herbal extracts from pharmacies rather than from Korean oriental medical clinics. The average patient number per month of uninsured herbal extracts was 13.64 people, the average dosage was 5.64g, the average cost per day was 3,859 won, and the average prescription period was 2.65 days. Korean oriental medical doctors asked an average of 12,486 won for the medical examination-prescription fee and 3,292 won in fees for prescriptions obtained outside the hospital. If insurance coverage expands to include these herbal extracts, their usage is expected to increase 2.31 times. Conclusions: This study shows Korean oriental medical doctors' use of herbal extracts and their opinions about execution of herbal extracts' insurance. A periodic study such as this one will hopefully aid in establishing polices for uninsured herbal extracts' insurance.

  • Objectives: The two criteria to clarify the toxicity of a herbal diet are well known. Although mechanical analysis of effective ingredients, a western approach, is widely used, the toxicity presence classification through the herbal analysis from a viewpoint of a theory of the herbal medicine properties has been disregarded. This study is for the safe use of a herbal diet through classification and study of toxicity presence in the herbal diet from the view of a theory of herbal medicine properties, one of the methods of Oriental Medicine. Methods: We classified and studied the toxicity presence in four kinds of herbal diets, waters and grains, animals groups, fruits and vegetables, and herbs and trees, excluding mineral natural drugs, of 1,400 kinds of medicines in 16 chapters of Tang-aec-pyeon, Dong-ui-bo-gam, for which the herbal analysis from a viewpoint of the theory of the herbal medicine properties has been used. The criteria of the toxicity presence in the herbal diet have been largely classified into the toxicant and the non-toxicant, and the toxicant is in turn classified into the insignificant, the medium and the significant. The category to clarify herbal diet has been limited to simultaneous utilization of food and natural drugs. The main text is Dong-ui-bo-gam, although diverse other references have also been used. Results: There are toxicant diets: a kind of tortoise meat of animals groups; five kinds of grains part in fruits and vegetables: aengdo, peach, oyat, small apple and gingko nut; and 12 kinds of vegetables part in fruits and vegetables: ginger, oriental cabbage, lettuce, chongbaek, onion, garlic, leek, fern, houttuynia cordata (myeol), pyeongji, geundae, and spinach, which should be prohibited from long-term use both as food and medicine. Conclusion: If herbal diet is used as health food supplements or food, the toxicity presence should be considered on the grounds of an Oriental Medicine theory of the herbal medicine properties.

  • Objectives : The objective of the study was to summarize randomized clinical trials(RCTs) that have assessed the effectiveness of herbal medicine on treatment of obesity and to propose better process of study. Methods : NLM Medline(pubmed), EMBASE, the Cochrane library, Science Direct, EBSCO, 4 Korean medical databases were systematically searched and 4 Korean medical journals were manually searched for clinical trials investigating the efficacy of herbal medicines on treatment of overweight or obese people from 1998 to 2008. The methodological quality was assessed using a Jadad score and validity was assessed using Oxford Pain Validity Scale(OPVS). Results : 14 RCTs met all the inclusion criteria. The methodological and ethical quality of the trials was generally low. The mean score by Jadad was 2.6 and the mean score of validity was 11.2. Complex herbal medicine was used in 8 RCTs and single herbal medicine was used in 6 RCTs. Except 1 RCT, the other RCTs reported positive effects of herbal medicine on treatment of obesity. Herbal medicines didn't seem to affect toxicity. In general adverse events relevant with the therapy were minor, but more than half of RCTs did not report about the safety or adverse events of herbal medicine, questioning their reliability. Conclusions : Although most RCTs concluded the efficacy and safety of herbal medicines on treatment of obesity, the quality of trials was low in general. Further rigorous clinical trials using complex herbal medicine should be performed.
