Objective: To evaluate the safety of total alkaloid sites of Gelsemium elegans by long-term toxicity test, and provide evidence for clinical application. Methods: Twenty-five female rats were randomly divided into five groups, which were labeled as drug group and blank control group respectively. According to different dosages, the drug group was divided into 1.10 mg/kg, 0.80 mg/kg, 0.50 mg/kg and 0.20 mg/kg groups. Before the test, the drug group and blank control group were fasting for 12 hours. The drug group was intraperitoneally injected once every two days, and the blank control group was intraperitoneally injected with an equal volume of normal saline under the same conditions. During administration, toxic reactions were observed in the administration group, and the number of deaths was recorded. After 30 days, the rats were anesthetized with 10% chloral hydrate and then sacrificed for cervical vertebra removal. The liver, spleen, lung and kidney were taken and the changes in organs in each group were observed. The paraffin sections were made and the fine structures were observed under the microscope. Results: During the administration period, the rats in the 1.10 mg/kg drug group died at the 4th and 5th doses, but the animals in the other dosing groups grew normally and no death was observed. After the rats were dissected, no abnormalities were found in the organs of each group from visual observation. Under microscope observation, 0.80 mg/kg and below did not cause the microscopic structure changes of liver, spleen, lung and kidney tissue, but 1.10 mg/kg could cause different degrees in damage to the four organs. %K 钩吻，总生物碱，长期毒性，大鼠
