　　福建省泉州市人民医院采用铁观音减肥茶对164个患肥胖病的人进行治疗，每天服减肥茶12～14克，15天为一个疗程。经过两个疗程的观察，患者的血脂、甘油三酯和胆固醇都有明显下降，体重也随之减少，治疗总有效率达70%以上。

　　3、清热降火

　　茶叶是防暑降温的好饮料。这是因为茶汤中含有茶多酚类、糖类、氨基酸、果胶、维生素等与口腔中的唾液起了化学反应，滋润口腔，所以能起到生津止渴的作用。同时，由于铁观音中的咖啡碱作用，促使大量的能量从人体的皮肤毛孔里散出。

　　4、敌烟醒酒

　　铁观音不仅能醒酒，而且能敌烟。由于铁观音中含有一种酚酸类物质，能使烟草中的尼古丁沉淀，排出体外。同时，铁观音中的咖啡碱能提高肝脏对药物的代谢能力，促进血液循环，把人体血液中的尼古丁从小便排泄出去，减轻和消除尼古丁带来的副作用。

　　二、铁观音的作用

　　1、抗动脉硬化

　　研究证明，茶多酚类化合物不仅可以降低血液中的胆固醇，而且可以明显改善血液中高密度脂蛋白与低密度脂蛋白的比值。咖啡碱能舒张血管，加快呼吸，降低血脂，对防治冠心病、高血压、动脉硬化等心脑血管疾病有一定的作用。

The efficacy and function of Tieguanyin tea

1. The effect of Tieguanyin

1. Anti-aging

Japanese researchers have shown that polyphenolic compounds in Tieguanyin can prevent excessive oxidation; purine alkaloids can indirectly scavenge free radicals, thereby achieving the purpose of delaying aging.

2. Weight loss and fitness

Studies have shown that Tieguanyin contains a large amount of tea polyphenols, which can not only improve the function of lipolytic enzymes, but also promote the metabolic activity of neutral lipase in tissues. Therefore, drinking Tieguanyin can improve the body shape of obese people, effectively reduce the subcutaneous fat and waist circumference of obese people, thereby reducing their weight.

The People's Hospital of Quanzhou City, Fujian Province used Tieguanyin slimming tea to treat 164 people suffering from obesity, taking 12-14 grams of slimming tea every day, 15 days as a course of treatment. After two courses of observation, the patient's blood lipids, triglycerides and cholesterol have decreased significantly, and the body weight has also decreased. The total effective rate of treatment is over 70%.

3. Clear heat and reduce fire

Tea is a good drink to prevent heatstroke and cool down. This is because the tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins, etc., which chemically react with the saliva in the mouth to moisten the mouth, so it can play a role in promoting body fluid and quenching thirst. At the same time, due to the effect of caffeine in Tieguanyin, a large amount of energy is released from the skin pores of the human body.

4. Diyan sobers up

Tieguanyin can not only sober up, but also fight against smoke. Because Tieguanyin contains a phenolic acid, the nicotine in tobacco can be precipitated and excreted. At the same time, the caffeine in Tieguanyin can improve the liver's ability to metabolize drugs, promote blood circulation, excrete nicotine in human blood from urine, and reduce and eliminate the side effects caused by nicotine.

Second, the role of Tieguanyin

1. Anti-arteriosclerosis

Studies have shown that tea polyphenols can not only reduce blood cholesterol, but also significantly improve the ratio of high-density lipoprotein to low-density lipoprotein in the blood. Caffeine can dilate blood vessels, speed up breathing, reduce blood lipids, and have a certain effect on the prevention and treatment of coronary heart disease, hypertension, arteriosclerosis and other cardiovascular and cerebrovascular diseases.

2. Prevention and treatment of diabetes

Clinical experiments have confirmed that drinking tea regularly can replenish vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in the human body in time, and can prevent the occurrence of diabetes. For patients with moderate and mild diabetes, blood sugar and urine sugar can be reduced to very little or completely normal; for patients with severe diabetes, blood sugar and urine sugar can be reduced, and various main symptoms can be relieved.

3. Prevention and treatment of dental caries

Drinking tea can protect teeth, which has long been used in ancient China. According to modern scientific analysis, Tieguanyin is rich in fluorine, while ordinary food contains very little fluorine. About 40% to 80% of the fluoride in Tieguanyin is dissolved in boiling water, and it is easy to combine with the calcium in the teeth to form a layer of calcium fluorophosphate on the surface of the teeth, which plays a role in preventing acid and caries.

Who is suitable for drinking Tieguanyin tea? People who are sleepy, weak, and indigestion are suitable for drinking Tieguanyin tea, which can eliminate fatigue and promote digestion. Secondly, people with a hot constitution and a strong stomach can also drink it in moderation, which can relieve anger and replenish water. Greasy people, people who stay up late, and white-collar people are also suitable to drink Tieguanyin tea, but it should be noted that excessive drinking of strong tea is forbidden.
