However, due to the pile fermentation, the tea may have a slight heap flavor. Of course, if properly handled in later stages, this flavor can be minimized. Ripe tea is made from Yunnan large-leaf sun-dried green tea through pile fermentation. This fermentation involves a series of complex and intense biochemical reactions, including oxidation, degradation, and polymerization, carried out by beneficial bacteria. The substances produced during fermentation have unique health benefits.

In his speech, Academician Chen Zongmao pointed out that tea has a positive effect on the three major health killers for humans—cardiovascular disease and metabolic syndrome, cancer, and degenerative diseases. Tea is not only a comforting companion for the soul but also a drink that genuinely maintains our health. It's time to pick up this cup of tea. Currently, for us Chinese people, as well as those in other developed countries, the main killers threatening life are three diseases: cardiovascular disease and metabolic syndrome, cancer, and degenerative diseases. First, let's look at the effect of tea on cardiovascular disease and metabolic syndrome.

Black tea is a fully fermented tea. Traditionally, it was the only type of tea known in the West. Westerners tend to prefer black tea. Major production areas of black tea include China, Sri Lanka, India, Kenya, and others. Black tea goes through the processes of picking, withering, rolling, fermentation, and drying – an additional step of fermentation compared to green tea. Fermentation refers to the oxidation of the tea leaves in the air. This process reduces the levels of catechins and tannins in the tea leaves, producing new components such as theaflavins and thearubigins, as well as aromatic substances like alcohols, aldehydes, ketones, and esters. Therefore, black tea leaves appear black, or a mix of black and the orange-yellow of young buds; the tea liquor is deep red in color; it has a pleasant aroma; and due to the reduced bitterness and astringency, the taste is sweeter and more mellow. The Benefits and Effects of Black Tea 1. Diuretic Effect of Black Tea In black tea, caffeine and aromatic compounds work together to increase blood flow to the kidneys, enhance glomerular filtration rate, dilate renal microvessels, and inhibit water reabsorption by the renal tubules, thus promoting increased urine output.…

The benefits of drinking Pu'er tea are a common topic among tea enthusiasts. Anecdotal evidence from friends, aggressive marketing by tea merchants, and health lectures by tea experts all touch on this subject. Since the 20th century, scientific research has delved into the medicinal properties and therapeutic mechanisms of tea, such as polyphenols, theaflavins, and L-EGCG. Although research on Pu'er tea started later, it has produced significant results. These findings suggest that the various phytonutrients in Pu'er tea can have real effects on human health. Ancient and Modern Health Needs In Tibetan folklore, there is a saying: "Cha is blood (tea nourishes the blood), Cha is flesh (tea sustains the body), Cha is life (tea is essential for living)." They have long believed that Pu'er tea is a powerful health drink that can "counteract the toxicity of meat and dairy."

Tea contains oxalic acid, especially strong tea, which has a higher content. Many people in daily life prefer strong tea, believing that is the true way to enjoy tea and not waste it. However, because of its high oxalate content, strong tea may lead to hyperoxaluria in the urinary tract, potentially forming calcium oxalate stones. In severe cases, it can even cause kidney stones. Some also say that regularly drinking strong tea can trigger hypertension. This is because tea contains caffeine, which can raise blood pressure, causing symptoms such as dizziness and headaches when consumed in strong teas.   For example, drinking green tea can stimulate excessive secretion of stomach acid, diluting gastric juices and affecting normal digestion of food. If digestive issues persist for a long time, symptoms like bloating and abdominal pain may appear, or even duodenal ulcers could develop. Additionally, regularly consuming tea, particularly strong tea, can overexcite the nervous system, leading to a faster heartbeat. Drinking tea before bed, especially strong tea, can cause poor sleep quality or insomnia. What Problems Can Arise from Regularly Drinking Strong Tea? 1. Regular consumption of strong tea promotes osteoporosis. Tea contains a relatively high amount of caffeine, which can…
