Does Tieguanyin tea cause “internal heat” or reduce it?

Tieguanyin, a type of tea, is considered slightly cooling in nature according to Traditional Chinese Medicine (TCM). It offers numerous health benefits, including calming the mind and improving eyesight, antibacterial and anti-inflammatory effects, aiding weight loss and enhancing skin beauty, and delaying aging.

Does Tieguanyin Cause or Alleviate “Internal Heat” (Shanghuo)?

Tieguanyin is a renowned traditional Chinese tea belonging to the oolong (qingcha) category and ranks among China’s Top Ten Famous Teas. Therefore, drinking Tieguanyin does not cause “internal heat.” As a lightly fermented tea, Tieguanyin is inherently cooling in nature; regular consumption can help alleviate “internal heat.” However, individuals with poor gastrointestinal function or chronic gastritis should avoid excessive intake, as it may irritate the stomach. Those suffering from frequent insomnia should also limit their consumption of Tieguanyin.

In daily life, regularly drinking Tieguanyin may help prevent certain diseases—such as malignant tumors—and can lower blood lipid and cholesterol levels, thereby reducing the risk of cardiovascular and cerebrovascular diseases. It may also provide supportive benefits for diabetes management. Clinically, Tieguanyin does not induce “internal heat”; rather, it helps alleviate symptoms associated with “internal heat,” such as oral ulcers, acute upper respiratory tract infections, and related inflammatory conditions. Additionally, Tieguanyin enhances immune function and neutralizes excess free radicals in the body, contributing to skin health and beauty. Rich in amino acids, vitamins, minerals, tea polyphenols, and alkaloids, Tieguanyin contains multiple nutrients and bioactive compounds that confer health-promoting and therapeutic effects.
