Tieguanyin is not only a precious natural beverage but also has excellent beauty and health benefits. However, although Tieguanyin is beneficial, it is not suitable for everyone, especially given the uneven quality in the market. Therefore, consumers must choose carefully.

Medical research shows that the combination of crude catechins in Tieguanyin has strong antioxidant activity, which can eliminate active oxygen molecules in cells, thereby protecting the human body from aging and diseases. The content of manganese, iron, fluorine, potassium, and sodium in Anxi Tieguanyin is higher than in other teas, with its fluorine content ranking first among all tea types, making it particularly effective in preventing tooth decay and senile osteoporosis. Anxi Tieguanyin is also known as the "Beauty Tea" and "Weight Loss Tea".

Scientific research indicates that Tieguanyin has a high selenium content, ranking among the top in the six major tea categories. Selenium can stimulate immune proteins and antibodies to resist diseases and inhibit the occurrence and development of cancer cells. Additionally, Tieguanyin has intelligence-enhancing effects. British scientists have found that the acidity and alkalinity of human brain fluids are related to intelligence. Tea is an alkaline beverage, and Tieguanyin is significantly alkaline, so regular consumption can regulate the body's acid-base balance and improve intelligence. Furthermore, Tieguanyin is rich in vitamins, caffeine, amino acids, minerals, tea polyphenols, and other substances, which have been scientifically proven to be closely related to brain development and have a positive impact on improving intelligence.

Diabetes is a global disease. Currently, there are approximately 200 million people with diabetes worldwide, and over 30 million in China. Diabetes is a chronic systemic disease characterized by disordered sugar metabolism. Typical clinical symptoms include "three excesses and one deficiency": excessive drinking, excessive urination, excessive eating, and weight loss, along with general weakness. In traditional Chinese medicine, this condition is called "wasting-thirst" and falls under the category of lower-jiao damp-heat. The main cause of the disease is a deficiency of polyphenolic substances in the body, such as vitamin B1, pantothenic acid, phosphate, methyl salicylate, etc., which disrupt sugar metabolism, leading to a sharp increase in blood sugar levels and weakened metabolic functions. Clinical experiments by Japanese medical doctor Dr. Ogawa Goshichiro and others have confirmed that regular tea consumption can timely supplement the body with vitamin B1, pantothenic acid, phosphate, methyl salicylate, and polyphenols, preventing the onset of diabetes. For patients with moderate or mild diabetes, it can significantly reduce blood sugar and urine sugar levels or even normalize them completely; for severe diabetic patients, it can lower blood sugar and urine sugar levels and alleviate various major symptoms.

However, Tieguanyin is not suitable for everyone. Due to its high content of polyphenols, aldehydes, alcohols, and other substances, these components have little impact on healthy individuals. However, for those with poor gastrointestinal function, especially those with chronic gastrointestinal inflammation, these substances can irritate the gastrointestinal mucosa, making it easier for individuals with originally weak gastrointestinal function to develop stomach issues. Therefore, it should not be consumed excessively, especially on an empty stomach. Additionally, Tieguanyin contains relatively high amounts of caffeine, active alkaloids, and various aromatic substances, which can stimulate the central nervous system. Patients with neurasthenia or cardiovascular diseases should consume it in moderation and avoid drinking it before bedtime.
