Objectives : This study was carried out in order to toxicity and safety of Drosera Rotundifolia L. pharmacopuncture in BALB/c mice. Methods : In order to investigate toxicity and safety of Drosera Rotundifolia L. pharmacopuncture, BALB/c mice were chosen in these studies and injected to ST36. In 50% Lethal Dose (LD 50) study, mice were divided into 8 groups. Doses of pharmacopuncture at 300, 600, 1,200, 2,400, 3,600, 4,800, 6,000, 7,200 mg/kg were given to the each group. we observed mortality and toxic signs for 7 days after injection. In single-dose toxicity, mice were divided into 4 groups. Doses of pharmacopuncture, 300, 600, 1,200 mg/kg, were administered to the experimental group. And a dose of normal saline, 0.2 ml was administered to the control group. We observed mortality and toxic signs for 14 days after injection. In repeated-dose toxicity for 4 weeks, mice were divided in 4 groups. Doses of pharmacopuncture, 150, 300, 600 mg/kg, were administered to the experimental group. And a dose of normal saline, 0.2 ml, was administered to the control group. We observed mortality, toxic signs, body weight, hematological values et al. Results : The LD 50 of Drosera Rotundifolia L. pharmacopuncture was 4,800 mg/kg. In single-dose toxicity, no deaths, no toxic signs occurred in any of groups. In repeated-dose toxicity for 4 weeks, no deaths, no toxic signs occurred in any of groups. Conclusions : No Observed Adverse Effect Level (NOAEL) of Drosera Rotundifolia L. pharmacopuncture injection for 4 weeks was more than 600 mg/kg.
