Green Tea Applicable Uses:Protecting Against Cardiovascular Disease.

Green Tea Extract INCI Name Camelia Sinensis Extract EINECS ELINCS No 283-519-7 CAS 84650-60-2 Tea Polyphenols photo picture image Cardiovascular system:The extracts have shown to reduce many of the risk factors associated with cardiovascular disease including high cholesterol and triglyceride levels, blood clotting, adhesions, etc.

 Heart disease and stroke are associated with a number of risk factors. The surprising news is that green tea appears to mitigate many of these risk factors.

 Green tea has been shown to lower LDL cholesterol and serum triglyceride levels. The potent antioxidant effects of green tea inhibit the oxidation of LDL cholesterol in the arteries. The oxidation of LDL cholesterol plays a major contributory role in the formation of atherosclerosis

 The formation of abnormal blood clots (thrombosis) is the leading cause of heart attack and stroke, and green tea has been shown to inhibit abnormal blood clot formation as effectively as aspirin. When looking at coagulation risk factors in the blood, green tea specifically inhibits platelet aggregation and adhesion via effects that differ from those of aspirin.

 Green tea reduces the risk of arterial blood clotting by two known mechanisms. First, green tea inhibits thromboxane A2 formation, as does aspirin. Second, green tea inhibits another clotting agent called platelet activating factor (PAF). Reducing thromboxane A2 levels is highly desirable. Thromboxane not only causes arterial blood clots, but also causes arterial constriction. The inhibition of thromboxane can prevent a heart attack or a thrombotic stroke.

 Green tea also has been shown to elevate levels of HDL, the good cholesterol that helps remove atherosclerotic plaque from arterial walls.

 Note that aspirin has some anti-thrombotic effects that differ from green tea, such as inhibition of cyclooxygenase. If you are taking low-dose aspirin to prevent a heart attack or stroke, you should continue doing so even if you also consume green tea.

 If you are going to use green tea to lower cholesterol, triglycerides or thrombotic risk factors, make sure you have your blood tested and evaluated by a competent medical professional.

 Epidemiological studies:

 Many epidemiological studies have examined associations between tea consumption and manifestations of cardiovascular disease, including myocardial infarction (heart attack) and stroke. A meta-analysis that combined the results of ten prospective cohort studies and seven case-control studies found that a three-mug (24-ounce) increase in daily tea consumption was associated with an 11% decrease in the risk of myocardial infarction (MI). However, caution was urged in the interpretation of these results because of bias toward the publication of studies suggesting a protective effect. Since then, the results of several other prospective cohort studies have been mixed. A six-year study of Dutch men and women found that those who drank at least three cups/day (~13 ounces) had a significantly lower risk of MI than those who did not drink tea. A seven-year study of U.S. women found that the risk of important vascular events (MI, stroke or death from cardiovascular disease) was significantly lower in a small number of women who drank at least four cups/day of black tea. However, so few women fell into this group that the significance of this finding is unclear. Finally, a 15-year study of U.S. men found no association between tea consumption and cardiovascular disease risk, but tea consumption in this population was relatively low, averaging one cup/day. Overall, the available research suggests that consumption of at least three cups/day of black tea may be associated with a modest decrease in the risk of MI. Although green tea consumption may confer a similar benefit, there has not been enough research on green tea consumption and cardiovascular disease risk to draw any firm conclusions.

 Endothelial function (blood vessel dilation):

 Vascular endothelial cells play an important role in maintaining cardiovascular health by producing nitric oxide, a compound that promotes arterial relaxation (vasodilation). Arterial vasodilation resulting from endothelial production of nitric oxide is termed endothelium-dependent vasodilation. Two controlled clinical trials found that the daily consumption of 4-5 cups (900-1250 ml) of black tea for four weeks significantly improved endothelium-dependent vasodilation in patients with coronary artery disease and patients with mildly elevated serum cholesterol levels compared with the equivalent amount of caffeine alone or hot water. The beneficial effect of black tea consumption on vascular endothelial function could help explain the modest reduction in cardiovascular disease risk observed in some epidemiological studies.
