Interestingly, although Panax notoginseng has been traditionally used for its hemostatic properties (its ability to stop bleeding), there are no randomized trials in humans to prove this benefit.
Panax notoginseng appears to exert some cardiovascular benefits. In one meta-analysis, people with unstable angina pectoris (UAP) who were treated with standardized oral or injectable preparations of P. notoginseng alongside traditional medicine showed a lower risk of cardiac morbidity as well as reduced symptoms and frequency of angina pectoris compared to the control. However, there was no decrease in the risk of cardiac mortality.[3]
However, it's important to interpret the results from these meta-analyses cautiously. The injectable and oral preparations used in the aforementioned studies typically contain Panax notoginseng as the main active ingredient as well as extracts from other plants. This complicates the determination of whether the observed results can be solely attributed to Panax notoginseng.
