Benefits of Drinking Black Tea
Black tea is made through fermentation and baking. During fermentation, the tea leaves turn into red oxides under the action of oxidase, becoming black tea. Black tea has a mild nature and mellow taste. In addition to containing various water-soluble vitamins, it is also rich in the trace element potassium, 70% of which can dissolve into the tea water after brewing. Potassium enhances heart blood circulation and reduces calcium consumption in the body. Because the manganese contained in black tea is one of the essential elements for bone structure, regularly drinking black tea is also beneficial for bone strength. Foreign data reports that regularly drinking black tea also has effects in preventing influenza, stroke, and skin cancer.
Research shows that because black tea contains a type of flavonoid compound, which acts similarly to an antioxidant, it can prevent stroke and heart disease. A recent US study showed that people who drink a cup of black tea daily have a more than 40% lower risk of heart disease compared to those who don't drink tea.

Drink Tea Often in Front of the Screen
Tea contains multiple vitamins and some trace elements, even more than in many fruits, offering many benefits for human health. Vitamin A in tea is beneficial for restoring and preventing vision decline; Vitamin B2 protects the eyelids, conjunctiva, and cornea of the eyes – its deficiency often causes tearing and blurred vision; Vitamin C is an important nutrient in the eye lens, and insufficiency can damage the lens, making it cloudy; Vitamin D directly participates in the synthesis of rhodopsin in the rod cells of the retina to maintain normal vision. The trace element zinc is necessary for the transport of Vitamin A in the body. If Vitamin D or zinc is insufficient, it weakens the eyes' dark adaptation ability and color discrimination.
Can You Take Medicine with Tea?
Whether you can take medicine with tea cannot be generalized. In most cases, it is not recommended to take medicine with tea, especially certain Western medicines containing iron agents (ferrous sulfate, ferrous carbonate, ferric ammonium citrate, etc.), aluminum agents (such as aluminum hydroxide), and protein preparations. When these encounter the polyphenol substances in tea soup, they can produce combined precipitation, affecting efficacy. Some Chinese herbs like ephedra and coptis generally should not be taken mixed with tea. Additionally, tea contains caffeine, which has a stimulating effect. Therefore, when taking sedative, hypnotic, and antitussive drugs, it is also not suitable to take them with tea to avoid conflict in drug properties and reduced efficacy. Generally, it is believed that you should not drink tea within 2 hours after taking medicine.
How Many Times Should a Cup of Tea Be Brewed?
Different types of tea have different耐泡程度 (resistance to brewing). In daily life, people often have this experience: very tender high-grade tea is not very耐泡, usually after brewing twice, there is little tea flavor left. Ordinary black and green teas can often be brewed 3-4 times. The耐泡程度 of tea is certainly related to the tenderness of the tea leaves. But more importantly, it depends on the integrity of the processed tea leaves. The more finely broken the processing, the easier it is for the tea juice to be brewed out; the coarser, older, and more complete the tea leaves, the slower the tea juice is brewed out. But no matter what tea, the first brewing extraction can account for more than 50% of the total soluble substances. For ordinary tea leaves, the second brewing is generally about 30%, the third about 10%, and the fourth only 1-3%. From a nutritional perspective, 80% of vitamin C and amino acids in tea leaves are leached out after the first brewing, and after the second brewing, over 95% have been leached out. Other effective components like tea polyphenols and caffeine also have the largest amount leached in the first brew, and after three brews, they basically reach full extraction. Thus, for general black, green, and scented teas, the number of brews is usually limited to three. Oolong tea, because a large amount of tea leaves is used for brewing, can be brewed more times; bagged tea processed and packaged from broken black tea raw materials, due to being easy to extract, is usually suitable for one-time brewing.

Does Drinking Tea Affect the Whiteness of Teeth?
Drinking tea, especially strong tea over the long term, and the polyphenol oxides in tea adhering to the tooth surface, if you don't brush your teeth, can indeed gradually yellow the teeth, just like a teapot or teacup that hasn't been cleaned for a long time develops a layer of "tea scale." If you drink strong tea and also have smoking habits, it often intensifies the yellowing of teeth, which is a problem worth noting. However, for general tea drinkers, as long as they don't smoke, pay attention to brushing teeth twice a day, and often eat some fruits and other foods appropriately, their teeth will definitely not turn yellow.
