The Health Secrets of Dark Tea

Tea News · Jun 18, 2026

        Dark Tea has been revered by frontier herders since ancient times as the “drink of life”. Scientific research has revealed that the miraculous health benefits of dark tea originate from the unique ice-agglomerate geological environment of Anhua. Because of this unique environment, Anhua dark tea produces “golden flowers”, or the probiotic Eurotium cristatum, during processing. This is the secret hidden behind “one stone, one golden flower”. In recent years, Anhua dark tea has been called “slimming tea” by Koreans, “beauty tea” by the Japanese, and “digestive tea” by Taiwanese.

Potassium

1. Regulates appropriate osmotic pressure within cells.

2. Regulates the acid-base balance of body fluids.

3. Participates in the metabolism of intracellular sugars and proteins.

4. Maintains normal nerve excitability and myocardial movement.

5. In cases of hypertension caused by high sodium intake, potassium has a blood pressure-lowering effect.

Germanium

Germanium can adsorb toxic substances and heavy metals in the human body and decompose them, achieving detoxification and beautifying effects, promoting blood circulation, and relieving fatigue. Germanium also has the effect of cooling blood to stop bleeding and clearing fire to calm the liver. In addition, germanium has effects such as anti-tumor, lowering high blood pressure, anti-aging, and preventing arteriosclerosis.

 


Selenium

Antioxidant effect, maintains normal immune function, has anti-tumor effects. Maintains normal physiological functions.

In addition, Anhua dark tea uses leaves of relatively mature maturity, making its internal content very rich.

Tea Polysaccharides

Alleviates sugar absorption in the small intestine, promotes sugar decomposition, lowers blood sugar, and protects pancreatic islet cells. Tea polysaccharides are a type of organic compound similar to Ganoderma lucidum polysaccharides and ginseng polysaccharides. They can enhance the body's antioxidant function, scavenge free radicals in the body, thereby reducing or preventing damage to pancreatic islet cells by free radicals, improving the function of damaged pancreatic islet cells, promoting the repair and regeneration of pancreatic islet cells, and increasing insulin secretion, thus achieving a blood sugar-lowering effect.

Tea Pigments

Anti-lipid peroxidation, enhances immune function, lowers blood lipids, and bidirectionally regulates blood pressure and blood lipids. (Green tea is rich in tea pigments, but the tea pigments in green tea are not water-soluble, whereas the tea pigments in dark tea are converted from large molecules to small molecules through the pile-fermentation process, making the tea pigments water-soluble.)


High Dietary Fiber

1. Maintains digestive system health

2. Enhances the immune system

3. Lowers cholesterol and high blood pressure

5. Promotes bowel movements, cleanses the intestines, and strengthens the stomach

6. Prevents cardiovascular disease, cancer, diabetes, and other diseases
