Hypertension is a "silent killer" because it is a common risk factor for major chronic diseases such as cardiovascular disease, brain wind, diabetes, and brain diseases. It is one of the common chronic diseases in the country. It is closely related to brain vascular diseases (second place), heart disease (third place) and brain diseases (ranked sixth to eighth place) among the top ten causes of death in the country. Some studies have pointed out that drinking tea can help reduce blood pressure. Is this really the case?

Can drinking tea help reduce blood pressure?

The Chinese people's tea culture has a history of four to five thousand years. "Tea" has become one of our daily drinks. Some people even use tea instead of water to drink several cups a day. Research has found that drinking tea can help relax blood vessels and reduce blood pressure, so let’s see what experts and research say.

1. Red tea, green tea

University of California, United States (UCI) and University of Copenhagen, published in the "Cell Physiology and Biochemistry" Science Reveals Why Tea Is Good For Your Heart, it was found that epitacin gallate and epigallocatechin-3-gallate in tea leaves can stimulate the ion channel protein KCNQ5. This protein is present in the smooth muscle of the inner wall of the blood vessels, which can enable ionic ion lesion cells to reduce cell death and allow blood vessels to relax and achieve a lowering effect of hemostatic pressure.

The study also found that heating green tea to 35 degrees Celsius will change the academic component, making it more effective in activate the KCNQ5 action. However, because the body temperature is about 37 degrees Celsius, whether drinking iced tea or hot tea can help KCNQ5 reduce blood pressure.

2. Ulong tea

Ulong tea is semi-fermented tea, and the degree of fermentation is between green and red tea. Nakamura Sorasuke, director of the Tea Comprehensive Research Center of the Food Nutrition Environmental Science Institute of St. University of Shizuoka Prefecture, Japan, said that Ulong tea contains a special ingredient called "Olong Tea Polymerized Polyphenols (OTPP). According to the relevant research of multiple elixirs on Ulong tea, this Ulong tea polymerization polyphenol may have a positive impact on reducing blood pressure and adjusting triglyceride levels. At the same time, drinking Ulong tea may also bring benefits of weight loss.

3. Pu'er tea

Some studies have pointed out that Pu'er tea can eliminate fat and reduce weight. Pu'er tea can control blood lipids in animal experiments. In human experiments, there have been also seen a decrease in weight in the subjects, or they have found that drinking Pu'er tea is related to lowering blood lipids. Therefore, although Pu'er tea has not significant effect on lowering blood pressure, it is more proof in lowering blood lipids. Chen Siqing, the attending physician of the Department of Cardiology and Institutional Department of Yangming Jiaotong University, said that without research on the effect of Pu'er tea on lowering blood pressure, tea drinks cannot replace the function of drugs.

4.Brown Rice Tea

Recently, the LINE group reported a video that effectively lowered blood pressure. The protagonist said, "As long as you drink brown rice tea every day, you can get rid of high blood pressure problems without medicine." Wang Zhiwei, attending physician of the Department of Cardiology and Institutional Department of the Affiliated Hospital of Asia University, said that although brown rice has high nutritional value, it can inhibit sympathetic neural activities, promote kidney function, and accelerate the excretion of the elbow, there is currently no scientific research that has proven that brown rice tea can effectively reduce blood pressure or reduce blood fat. It is recommended that the public take the medicine as timely to effectively control blood pressure.

Just drink tea appropriately. If you want to lower blood pressure, please take medicine according to time to control the above teas. Although red tea, green tea, and Ulong tea have the effects of improving blood pressure and controlling blood lipids, this tea is only a helper and will never replace the medicine's blood pressure lowering function. If you want to lower blood pressure, you should avoid eating high-lipid and high-calcium sterol foods from your diet, take more high-fiber foods, exercise more frequently, and cooperate with doctors to control blood pressure to effectively fight high blood pressure and high blood fat.
