Benefits of drinking black tea
Black tea is made through fermentation and baking. During fermentation, tea leaves turn into red oxides under the action of oxidase, becoming black tea. Black tea has a mild nature and mellow taste. Besides containing various water-soluble vitamins, it is rich in the trace element potassium, 70% of which can dissolve into the tea when brewed. Potassium enhances heart blood circulation and reduces calcium loss in the body. Since the manganese in black tea is one of the essential elements for bone structure, regular consumption also benefits bone strength. Foreign reports indicate that regular consumption of black tea can prevent influenza, stroke, and skin cancer.
Research shows that due to a flavonoid compound in black tea, which acts similarly to an antioxidant, it can prevent stroke and heart disease. A recent US study revealed: compared to non-tea drinkers, those who drink a cup of black tea daily have a more than 40% lower risk of heart disease.
Not suitable to drink tea after meals
Drinking tea immediately after meals inevitably dilutes gastric juice, affecting food digestion. Simultaneously, the tannic acid in tea can coagulate substances in food, increasing stomach burden and affecting protein absorption. It is best to drink tea one hour after a meal.
Black tea can also fight cancer
Green tea's ability to induce cancer cell "suicide" has been confirmed by several experiments. So, what about black tea, where most tea polyphenols are oxidized during processing? Does it still have anti-cancer activity? A special study by the Tea and Health Laboratory of Hunan Medical University confirmed that black tea also has strong anti-cancer functions.
Drink tea often in front of the screen
Tea contains multiple vitamins and some trace elements, even more than many fruits, offering many benefits for human health. Vitamin A in tea helps restore and prevent 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 retinal rod cells to maintain normal vision. The trace element zinc is necessary for the transport of Vitamin A in the body. Deficiency in Vitamin D or zinc can reduce dark adaptation and color discrimination ability.
Can tea be used to take medicine?
Whether tea can be used to take medicine cannot be generalized. In most cases, it is not recommended to use tea to take medicine, especially certain iron-containing preparations (ferrous sulfate, ferrous carbonate, ferric ammonium citrate, etc.), aluminum-containing preparations (such as aluminum hydroxide), and protein-based preparations. When these Western medicines encounter polyphenols in tea soup, they may form precipitates, affecting efficacy. Some Chinese herbs like ephedra and coptis generally should not be taken with tea. Additionally, tea contains caffeine, which has a stimulating effect. Therefore, when taking sedative, hypnotic, or antitussive drugs, it is also not advisable to use tea to swallow them to avoid conflict in drug properties and reduced efficacy. Generally, it is recommended not to drink tea within 2 hours after taking medicine.
How many times should a cup of tea be brewed?
Different teas have varying resistance to brewing. In daily life, people often experience that very tender high-grade tea is not resistant to brewing, usually losing most of its flavor after 2 infusions. Ordinary black and green teas can often be brewed 3-4 times. The brewing resistance is related to the tenderness of the tea leaves but, more importantly, depends on the integrity of the processed leaves. The more finely broken the processing, the easier it is to extract the tea juice; the coarser and more complete the leaves, the slower the tea juice extraction. Regardless of the tea, the first infusion extracts over 50% of the total soluble substances. The second infusion of ordinary tea is generally about 30%, the third about 10%, and the fourth only 1-3%. Nutritionally, after the first brew, 80% of Vitamin C and amino acids in tea are extracted; after the second, over 95% are extracted. Other active components like tea polyphenols and caffeine are also largely extracted in the first infusion. After three brews, they are almost fully extracted. Thus, for general black, green, and scented teas, three infusions are usually sufficient. Oolong tea, due to the large amount of leaves used for brewing, can be brewed more times; bagged tea made from broken black tea raw material, being easy to extract, is usually suitable for one-time brewing.
What are the benefits of washing face and feet with tea?
Washing the face and bathing with tea can reduce the occurrence of skin diseases and make the skin glossy, smooth, and soft. Applying tea-soaked gauze to dark circles under the eyes, 1-2 times daily for 20-30 minutes each, can eliminate dark circles. Washing hands and feet with tea and dregs can prevent chapping, treat eczema, relieve itching, and reduce foot odor for those with sweaty feet.

How should patients with stomach problems drink tea?
There are many types of stomach diseases, the most common being superficial gastritis, atrophic gastritis, gastric ulcer, and gastric bleeding. Stomach patients generally should not drink tea while taking medicine. Two hours after medication, drinking some light tea, sugary black tea, or milk black tea can help reduce inflammation and protect the gastric mucosa, also having a certain effect on ulcers. Drinking tea can also block the synthesis of nitrosamine compounds in the body, preventing precancerous lesions.
Does drinking tea affect teeth whitening?
Drinking tea, especially strong tea over the long term, can cause polyphenol oxides from the tea to adhere to the tooth surface. If not brushed away, this can gradually yellow the teeth, much like a "tea stain" forming on unwashed teapots and cups. If drinking strong tea is combined with smoking, it often worsens tooth yellowing, which is a noteworthy issue. However, for general tea drinkers who do not smoke, pay attention to brushing twice daily, and regularly eat fruits and other foods, teeth will definitely not turn yellow.
