Objectives: In recent years, extensive focus has been laid on adulteration of herbal medicine with heavy metals. This may be mainly due to soil contamination by environmental pollution. The objective of this study is to identify the contents of various heavy metals in the blood from Ohjeok-san (Wuji-san) Decoction (OD) treated-rats. Methods: For this study, 13 kinds of metals including essential and heavy metals, i.e. A1, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se and Zn were analyzed by a slight modification of EP A methods and the following results are obtained. Results: 1. There was no significant difference between the OD-treated groups and control group in liver, kidney, bone, brain and weight, especially no significant difference at the 5th and 10th days in weight and the amount of food intake. 2. The amount of each metal analyzed in the blood were as follows; A1: 2.3~3.07 mg/l, As: 2.90~3.66 mg/l, Cd: 0~0.001 mg/l, Co: 0~0.01 mg/l, Cr: 0.40~043 mg/l, Cu: 0.93~1.88 mg/l, Fe: 414.35~464.46 mg/l, Hg: 0.01 mg/l, Mn: 0.10~0.17 mg/l, Ni: 0.01 mg/l, Pb: 0.03~012 mg/l, Se: 0.73 mg/l, Zn: 3.41~4.13 mg/l by groups, respectively. In control and experimental group, Experimental I and other experimental II, III, IV, and V groups, there were no significant differences. 3. The amount of non-toxic metals (A1, Co, Cu, Fe, Mn, Se, Zn) were $64.1{\pm}7.71{\;}mg/l$ in the control group and 60.70~67.58 mg/l in the experimental groups I, II, III, IV and V. The amount of Toxic metals (As, Cd, Cr, Ag, Pb) were $0.68{\pm}0.21{\;}mg/l$ in the control group and 0.57 ~ 0.66mg/l in the experimental groups. The total amount of metals were 32.35 mg/l in the control group and 30.48~34.12 mg/l in the test groups I, II, III, IV and V, respectively. Conclusions: There was no significant difference of metal concentration in the blood from the OD-treated-rats compared to those of the control group even if higher dosage (1~8 times the dosage for a person) of OD was administered. This may be mainly due to a decoction treatment which contains only supernatants filtered from the herb-mass after boiling. This indicates the legal limitation for metal concentration in herbal medicine must be applied according to different treatment methods of herbal medicine.

Objective: This study reports the effect of Korean traditional medicine on persistent chemotherapy-induced peripheral neuropathy (CIPN). Methods: The patient was treated with Korean traditional medicine that included acupuncture, moxibustion, and herbal medicine. The effectiveness of the treatment was evaluated by the Quality of Life Questionnaire-Core 30 (QLQ-C30), the Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy (QLQ-CIPN20), the Medicinae Doctor Anderson Symptom Inventory (MDASI), and a numeral rating scale (NRS). We also used the Beck Depression Inventory (BDI) to evaluate the patient's mood change after relieving the paresthesia. Results: After treatment, the symptoms were improved. Paresthesia decreased 80%p after Korean medicine treatment. Conclusions: According to this study, Korean traditional medicine can be an effective treatment for paresthesia in patients suffering from CIPN over 2 years.

Background : Traditional herbal medicine is used extensively among the Korean populations, and other Asian countries employ similar therapies as well. In recent years, extensive focus was laid on adulteration of the herbal medicine with liver damage. The use of herbal preparations as remedies for various medical conditions has continuously increased in Korea. Large proportions of Korean patients use herbal medicinal products, folk remedies, and health food. However, studies on the safety of herbal products are conducted on a less than sufficient basis even in the countries like Korea where herbal medicine is being used extensively. Some of the reports on the safety of herbs were done by the doctors of western medicine but lack of knowledge and misclassification led to misunderstandings. Objectives : This study aims to verify the evidences on safety of frequently used 4 herbal medications (Sipjeondaebo-tang, Bojungikgi-tang, Ohjeok-San, Yukmaijihwang-tang) in the lab animal model. Methods : Sprague-Dawley rats was treated by 4 herbal medications during 31 days. After 1 month, we checked body weight, liver weight, and serum enzyme associated with liver function. Results : There is no significant difference in body weight and liver weight after 1 month of administrations. In all experimental groups, no abnormal findings was observed in histotogical research and lab liver Functions test(AST, ALT etc). Conclusions : These four herbal medications, frequently used in oriental medicine clinics and hospitals, are safe from hepatoxic events in the lab animal model.
