Identification of target protein is an important procedure in the course of drug discovery. Because of complexity, action mechanisms of herbal medicine are rather obscure, unlike small-molecular drugs. Inverse docking simulation is a reverse use of molecular docking involving multiple target searches for known chemical structure. This methodology can be applied in the field of target fishing and toxicity prediction for herbal compounds as well as known drug molecules. The aim of this review is to introduce a series of in silico works for predicting potential drug targets and side-effects based on inverse docking simulations.

Consumption of herbal products from the medicinal plants contaminated with heavy metals can cause serious consequences on human health. This is a major concern for traditional and herbal medicine. The present study was carried out to analyze and quantify the levels of six potentially toxic heavy metals namely arsenic, lead, cadmium, mercury, chromium and nickel in ten important Indian medicinal herbs. The air dried raw herbs were processed by microwave assisted wet digestion and analyzed by using atomic absorption spectrophotometer equipped with graphite tube atomizer. Except the chromium content in three plants, all the levels of six heavy metals analyzed were found to be quite below the permissible limits in all the ten raw medicinal herbs analyzed. The present work implies that, regular and systematic screening of raw medicinal herbs is necessary to check the levels of the heavy metal contaminants before using them for consumption or preparation of herbal formulations so that the possible contamination cannot cumulate up to the finished products.

1. Objectives: Pharmacopuncture according to Sasang Constitutional Medicine is new field of constitutional medicine. We investigated safety of pharmacopunctures to develop this treatment. 2. Methods: We searched for papers in fifteen Korean oriental medical journals and four online searching portal articles. Hepatotoxicity, nephrotoxicity and general toxicity tests were investigated about one hundred thirty kinds of pharmacopunctures. 3. Results: Toxicity test about 36 kinds of 130 pharmacopunctures were investigated. 1) Hepatotoxicity and nephrotoxicity test of pharmacopunctures were searched in 11 of 38 Soeumin herbs, 8 of 36 Soyangin herbs, 5 of 44 Taeeumin herbs and 1 of 12 Taeyangin herbs. From among these herbs, toxicity was detected in Radix aconiti lateralis preparata(附子), Fructus alpiniae oxyphyllae(益智仁), Semen crotonis(巴豆), Radix bupleuri(柴胡) and Semen armeniacae amarum(杏仁) pharmacopunctures. 2) General toxicity test of pharmacopunctures were searched in 8 of 38 Soeumin herbs, 9 of 36 Soyangin herbs, 6 of 44 Taeeumin herbs and 2 of 12 Taeyangin herbs. from among thes herbs, toxicity was detected in Radix aconiti lateralis preparata(附子), Radix ginseng(人蔘), Semen crotonis(巴豆), Rhizoma seu radix notopterygii(羌活), Radix aralia cordatae(獨活), Semen armeniacae amarum(杏仁) and Radix scutellariae(黃芩) and Cortex acanthopanacis(五加皮) pharmacopunctures. 4. Conclusions: From these results, we must decide extraction method, concentration and dose carefully to use the toxic pharmacopuncture. More toxicity test and further study is needed about pharmacopuncture treatment in Sasang Constitutional Medicine.

Objectives: This study was performed to evaluate the skin irritation toxicity of processed sulfur. Methods: All experiments were conducted at Medvill (Korea), an institution authorized to perform non-clinical studies, under the Good Laboratory Practice (GLP) regulations. In order to investigate skin irritation toxicity of processed sulfur, we divided the back of six rabbits into two control sites and two test sites. One of each of the two control and test sites was then designated abraded sites and intact sites. In test sites, 0.5 g of processed sulfur was applied to the back of the rabbit for 24 hours, and in control sites, 0.5 g of sterile distilled water was applied in the same way. We observed and evaluated mortality, weight, general symptoms, and skin irritation toxicity. This study was conducted with the approval of the Animal Ethics Committee (Approval number: IAC2020-1549). Results: In all experiments, no dead animals were observed. In all cases, skin coloration was observed at 24 hours after processed sulfur administration. This coloration lasted up to 48 hours and is believed to be the effect of the administration of test substances. Weight measurement indicated that weight was lost 72 hours after administration in three cases, but this is considered an accidental weight change. Normal weight gain was observed in the remaining subjects. In all animals, no skin irritation toxicity was observed, and the primary irritation index (P.I.I) was calculated as 0.0 according to Draize's evaluation method. Conclusion: The above findings suggest that it is relatively safe to apply a processed sulfur to the skin. Further research on this topic is needed to provide more specific evidence.

Objectives : About 13% of the medicines used by traditional korean medicines(TKM), are called animal medicines and are derived from non-herbal sources such as animals and insects. However, the clinical use of these preparations from animal medicines is often based on tradition and belief, rather than on evidence of toxicity and efficacy. As a result, animal medicines containing toxin have caused serious problems from injecting patients with venom. Here, various venoms frequently used as TKM were reviewed in terms of their instinct toxity and tried to estimate their safety classification. Methods : The estimation of safety classification was based on human equivalent dose(HED)-based MOS (margin of safety) and clinical dose applied for patients. Results and Conclusions : Except that of snake venom due to no clinical dose, they were evaluated as class 3 for bee venom, class 4 for cantharidin, toxin from blister beetle, and class 1 for venom from scolopendrid. In conclusion, animal medicines showed a wide range of safety classification from class 1 to class 4. This wide range is estimated to result from extremely limited applications of each venom for patients because of their strong toxicity. However, it should be cautious for application in clinics since animal medicines can produce anaphylactic reactions particularly after veinous administration even with a tiny amount of venom.

The subcronic toxicity of BDR-29, a herbal preparation of Cassiae Semen, Prunellae Spica, Tribuli Fructus, and Uncariae Rhamulus et Uncus, was examined in male and female Sprague-Dawley rats. Rats were treated with the test substance at a dose 5 mg/kg, 50 mg/kg and 500 mg/kg intragastrically for 13 weeks. No death and abnormal clinical signs were observed throughout the administration period. There were not significantly different from control group in net body weight gain, food and water consumption, organ weight, gross pathological findings, and urine analysis among the groups rats treated with different doses of the BDR-29. Hematological findings and biochemical examination revealed no evidence of specific toxicity related to BDR-29. From these results, no observation effect level (NOEL) of BDR-29 is 500 mg/kg/day under the condition employed in this study.
