II. History and Heritage of Dark Tea
The history of dark tea can be traced back to ancient times, originating from southwestern China before gradually spreading across the country and the world. Throughout its long history, dark tea has witnessed countless changes and carried people's aspirations for a better life. The production techniques of dark tea have been passed down through generations of tea makers, evolving into the exquisite and unique craft we see today. From picking mature leaves to undergoing processes such as withering, rolling, pile-fermentation, and drying, each step embodies the wisdom and dedication of tea makers. This inheritance of traditional techniques is not only a respect for cultural history but also a commitment to quality.
III. Nutritional Value and Benefits of Dark Tea
(a) Rich Nutritional Components
Dark tea contains various vitamins, including Vitamin B1 which effectively treats beriberi and polyneuritis, Vitamin B2 used as an auxiliary treatment for keratitis and conjunctivitis, and Vitamin C that plays a positive role in preventing scurvy and arteriosclerosis caused by high blood pressure. Additionally, dark tea is rich in minerals such as sodium, potassium, iron, copper, phosphorus, and fluoride, making it an important source of essential minerals for ethnic minorities who lack fruit and vegetable intake. Furthermore, the high fluoride content in dark tea helps prevent various dental diseases and maintain healthy teeth.
(b) Important Nutritional Source
Tea naturally contains certain proportions of leaf protein, free amino acids, carbohydrates, and lipids, all of which are essential nutrients for the human body. During the production process, dark tea undergoes special processing, allowing these nutrients to be better preserved and released. Proteins, amino acids, and sugars not only provide energy to drinkers but also play a vital role in maintaining good health.
(c) Functional Components
In addition to basic nutritional components, dark tea is rich in functional components such as tea polyphenols, caffeine, polysaccharides, pigments, and vitamins. These components play important roles in immune regulation, antioxidant activity, and cancer prevention. Tea polyphenols have the ability to eliminate free radicals and effectively delay cellular aging; caffeine stimulates gastric juice secretion, enhances appetite, aids digestion, and has diuretic and stimulating effects; polysaccharides exhibit significant effects in lowering blood lipids and blood sugar levels.
(d) Specific Benefits and Effects
1. Supplementing Dietary Nutrition
The rich nutritional components of dark tea make it a good choice for supplementing dietary nutrition.
2. Aiding Digestion
The presence of caffeine, vitamins, and amino acids helps promote digestion, regulate fat metabolism, and stimulate appetite.
3. Lowering Blood Lipids

4. Antioxidant Activity
Multiple antioxidant components work together to resist the harm of free radicals to the body, delaying aging.
5. Cancer Prevention and Treatment
Has a noticeable inhibitory effect on tumor cells.
6. Lowering Blood Pressure
Theanine can inhibit blood pressure increases by activating dopaminergic neurons.
7. Lowering Blood Sugar
Tea polysaccharide complexes are key components in lowering blood sugar.
8. Antibacterial and Anti-inflammatory
Flavonoids and thearubigins have significant antibacterial effects on various bacteria.
9. Diuretic and Detoxifying
Caffeine promotes urine production and helps sober up and detoxify the body.
IV. Production Techniques of Dark Tea
(a) Picking
Carefully select suitable fresh tea leaves, laying the foundation for subsequent processing.
