If Dahongpao is the king of the tea market, then Tieguanyin is its prime minister. Why is that? Dahongpao relies on its kingly aura, while Tieguanyin determines the successful operation of the tea market, because the annual sales volume of the tea market is almost contributed by Tieguanyin. The effects of Tieguanyin are the reason for its success. So, what makes Tieguanyin so successful?

One answer is tea polyphenols. Contrary to what many people think, tea polyphenols are not a specific substance but a general term for a series of compounds, including flavanols, catechins, phenolic acids, and anthocyanins. Their content in tea leaves ranges from 20% to 35%. Among tea polyphenols, flavanols are the main component, with catechins being the most important, accounting for about 60% to 80% of the total tea polyphenols.

Tea polyphenols have many benefits for the human body. First is their medical efficacy. The most notable effect of tea polyphenols is their ability to fight cancer and prevent aging. This is because they can scavenge free radicals that harm the body, thereby increasing enzyme activity, preventing cell mutation, and effectively fighting cancer. Tea polyphenols can also prevent the formation of many diseases, significantly enhance human immunity, and promote physical health.

Tea polyphenols also achieve certain health benefits. This is why people drink Tieguanyin as a healthy beverage. They can not only resist excessive lipid oxidation and detoxify heavy metal salts and alkaloid poisoning, but also provide radiation protection, alleviate adverse reactions to chemotherapy, aid digestion, prevent tooth decay and bad breath, and have cosmetic and skin care effects.

Finally, tea polyphenols are now applied in many fields. They are widely used in the food industry for making pastries and dairy products, preserving fruits and vegetables, beverage production, and storing meat and edible oils.

Tea polyphenols offer numerous benefits to people, and this is one of the functions of Tieguanyin. With this advantage, Tieguanyin has achieved a dominant position in the tea market in terms of sales volume.
