The rats were treated with the doses of g extract/kg per day and g extract/kg per day for a period of 90 consecutive days. Tri Thien Duoc hard capsule caused no significant dose-related changes in general status, hematological parameters, renal and hepatic function tests; in addition, it did not cause any change in histology of the liver and kidney of the rats. Our finding obtained that the Tri Thien Duoc hard capsule did not cause subchronic toxicity in experimental animals. | JOURNAL OF MEDICAL RESEARCH EVALUATION OF SUBCHRONIC TOXICITY OF TRI THIEN DUOC HARD CAPSULE IN EXPERIMENTAL ANIMALS Nguyen Thi Thanh Loan1, Pham Thi Van Anh1, Vu Thi Ngoc Thanh1, Nguyen Thi Ngoc Tram2 1 Ha Noi Medical University Thien Duoc Limited Company 2 Tri Thien Duoc, a formulation of Portulaca oleracea L. and Amaranthus spinosus L., is aimed to treat hemorrhoids and other related conditions; however, the safety of this product’s long-term consumption has never been reported.
