| Jiaogulan's and Cardiovascular Health |
Jiaogulan is a regular part of the training regimen for many runners, swimmers and endurance athletes. The anti-oxidant effects aid in muscle recovery. Moreover, research suggests Jiaogulan may directly improve cardio-vascular function. Better cardio-vascular function means more oxygen reaching muscles and hence improved athletic performance.
More Efficient Cardio Function
Zhou, Ying-Na et al. Effects of gypensosides-containing tonics on the pulmonary functions in exercise workloads. Journal of Guiyang Medical College. 1993
Researchers at the Guiyang Medical College in China conducted studies of 220 athletes and 30 average subjects using color DOPLER imaging. The study showed that just 30 minutes after receiving a dose of gypenosides, 100% of the test subjects showed positive effects. The effects measured included, increased stroke volume and cardiac output, decreased left ventricular end-systolic diameter and increased left ventricular end-diastolic diameter. The heart rate and blood pressure did not increase. This implies that Jiaogulan improved the efficiency of the pumping action of the heart such that the heart did not have to work as had to produce the same volume of blood flow.
Higher Coronary Flow and Lower Heart Rate
Chen, L.F., et al. Comparisons of the effects of Gypenosides and ginsenosides on cardiac function and hemodynamics in dogs. Zhongguo Yaolixue Yu Dulixue Zazhi. China 1990
Dr. Chen and his team studied the effects of jiaogulan and ginseng on the cardiovascular efficiency of dogs. They found that the dogs that received Jiaogulan significantly lowered their systolic and diastolic blood pressure and decreased their total peripheral, brain and coronary blood vessel resistance. Ginseng was found to have a similar but less significant effect.
Jiaogulan found to be an "anti-thrombotic agent."
Tan H et al. Antithrombotic effect of Gynostemma pentaphyllum Zhongguo Zhong Xi Yi Jie He Za Zhi. 1993 May;13.
Thrombosis is another term for blood clotting. Clots can lead to heart attack and stroke. Researchers in China found that a water extract from Jiaogulan "could inhibit significantly the platelet aggregation induced by ADP and compound agonists (P < 0.05), accelerate obviously the disaggregation (P < 0.05) and inhibit effectively the experimental thrombosis (P < 0.05). The delayed effects of GP on KPTT, PT, TT, AT, RVV-RT, RVV-CT suggested that this drug could decrease the activity of multiple coagulation factors. And it showed that GP could accelerate the erythrocyte electrophoresis rate. This study revealed that GP is an antithrombotic agent affecting the links of thrombotic chain."
Jiaogulan Linked to Nitric Oxide Production in Blood Vessels
Tanner, MA et al. The Direct Release of Nitric Oxide by Gypenosides Derived from the Herb Gynostemma pentaphyllum. Nitric Oxide Oct. 1999.
Dr. Tanner and his team from Vanderbilt University Medical Center investigated the vasorelaxation effects of Jiaogulan. They found that gypenosides from Jiaogulan caused the lining of blood vessels to release nitric oxide.. The nitric oxide release relaxed the blood vessels resulting in more efficient blood flow.
Potential Preventive Effects on Myocardial Infarction
Xiong, WS et al. Protective effects of gypenosides on experimental myocardial infarction. Zhongguo Yao Li Xue Bao. 1990 Sept,11.
Dr. Xiong studied the effects of Jioagulan on myocardial infarction. He found in an animal study that the gypenosides in Jiaogulan reduced the size of myocardial infarctions and the free fatty acids in the blood serum. He suggests that the effect is related to the strong anti-oxidative properties of Jiaogulan.
