What elements does Pu-erh tea contain? What effects do they have on the human body?

1. The caffeine in Pu-erh tea can stimulate the central nervous system, eliminate fatigue, improve work efficiency, and counteract the toxic effects of alcohol, tobacco, and morphine. It has stimulating and cardiotonic effects on the heart and central peripheral vascular system, increases renal blood flow, enhances glomerular filtration rate, has a diuretic effect, relaxes smooth muscles, and helps regulate body temperature.

2. Pu-erh tea contains Vitamin B2. A deficiency in B2 can cause metabolic disorders and oral diseases. The content of Vitamin B2 in tea is 1.2 mg per 100 grams.

3. Pu-erh tea has a high Vitamin C content, which is fully soluble in water and can be efficiently utilized. The enzymes in tea have physiological effects in the body similar to some vitamins, and some vitamins are components of enzymes.

4. The protein in Pu-erh tea consists of amino acids. Young tea leaves contain 2-5% amino acids, with over 20 types, most of which are beneficial to humans. Theanine content is relatively high, which is a unique amino acid in tea. Others include lysine, arginine, histidine, cystine, etc. These amino acids promote human growth and intellectual development and have positive effects in preventing premature aging, osteoporosis, and anemia.

5. The carbohydrate content in Pu-erh tea is about 30%, with approximately 5% being soluble upon brewing. Lipids account for 2-3% of tea, including phospholipids, glycolipids, and triglycerides. The fatty acids in tea are mainly linoleic acid and linolenic acid, both essential for humans and important components of brain phospholipids and lecithin.

6. Tea contains 4-7% inorganic matter, most of which is soluble in water and absorbable by the human body. Potassium and phosphorus are the most abundant, followed by calcium, magnesium, manganese, aluminum, and trace amounts of copper, zinc, sodium, nickel, beryllium, boron, sulfur, and fluoride. Medical experts point out that inorganic matter helps maintain fluid balance (osmotic pressure) in the body, which is crucial for improving internal circulation. It also serves as raw material for 'hard tissues' (bones and teeth) and is closely related to their physiological functions. Potassium is an important component of intracellular fluid, and tea not only has high potassium content but is also easily brewed. Laboratory tests by Hunan Medical University confirm that fluoride in Pu-erh tea plays a significant role in preventing dental caries. Manganese in tea prevents reproductive disorders and convulsions, zinc promotes children's growth and development, prevents myocardial infarction and sudden death, and has anti-cancer effects. Copper and iron in tea aid hematopoietic functions.

Drinking tea is not only about appreciating its taste but also understanding how it benefits us.
