"Tianjian" tea can be brewed with boiling water or prepared as a blended drink; in Guangdong, where dark tea consumption is high, it is often brewed in a pot or prepared as a cold infusion at home. Tianjian tea has a sweet, smooth, and refreshing taste with a pure flavor and a distinctive pine-smoke aroma. Historically a drink for royalty and nobility, it is now a daily beverage for the affluent in Guangdong. Tianjian tea also has the characteristic of improving with age, becoming more aromatic over time, leading many to collect and store it for future enjoyment. Gongjian tea, as the name suggests, was part of the tribute tea series in ancient times, with all tribute teas being of the highest quality. Gongjian, along with Tianjian and Shengjian, belongs to the "Three Tips" series, considered top-grade Anhua tea during the Qing Dynasty.
China has a long history of "using tea to treat illnesses." Anhua Tianjian Dark Tea is a fully post-fermented tea with the highest content of bioactive tea polysaccharides. The involvement of microorganisms gives it unique pharmacological effects that other teas cannot replicate. Clinical experiments on ten modern disease models studied the health functions of Tianjian Dark Tea, finding it highly beneficial for boosting immunity, fat metabolism, weight control, warming the stomach, promoting diuresis, and relieving constipation. It contains low caffeine and does not affect sleep.
The main component of Anhua Tianjian Dark Tea is tea polysaccharide complexes. These compounds are believed by the medical community to regulate sugar metabolism, lower blood lipids and blood pressure, improve glucose metabolism, reduce blood sugar, and prevent diabetes.
The tea polysaccharide complexes in Anhua Tianjian Dark Tea are the primary components for lowering blood sugar. Commonly referred to as tea polysaccharides, these are complex and variable mixtures. Tests on several tea types show that Anhua Tianjian Dark Tea has the highest tea polysaccharide content, with stronger bioactive components. This is due to the action of glycosidase, protease, and hydrolase during fermentation, which form shorter sugar and peptide chains. Shorter peptide chains are more easily absorbed and have higher bioactivity, which may explain why fermented teas, especially dark teas, are more effective at lowering blood sugar than other teas.
Anhua Tianjian Dark Tea has antibacterial and anti-inflammatory effects. The main components of its liquor are theaflavins and thearubigins. Studies show that theaflavins are not only effective free radical scavengers and antioxidants but also exhibit significant antibacterial effects against Clostridium botulinum, Enterobacteriaceae, Staphylococcus aureus, Capsular bacteria, and Bacillus cereus. Additionally, theaflavins inhibit influenza viruses, rotaviruses, and enteroviruses. Anhua Tianjian Dark Tea also promotes diuresis, detoxification, and reduces harm from tobacco and alcohol.
The diuretic effect of caffeine in Anhua Tianjian Dark Tea is achieved by increasing the filtration rate of water in the kidneys. Meanwhile, caffeine stimulates the bladder, aiding both diuresis and sobering up from alcohol. Additionally, tea polyphenols in dark tea precipitate nicotine from tobacco, which is then excreted through urine, and they neutralize free radicals in smoke, reducing its harmful effects. Tea polyphenols also strongly adsorb heavy metal toxins, so drinking more tea can alleviate heavy metal poisoning.
Anhua Tianjian Dark Tea has unique qualities and strong pharmacological effects, making it one of the most eco-friendly and healthy beverages in the world today, irreplaceable by other teas.
