Does oolong tea cause internal heat or reduce internal heat?

Generally speaking, oolong tea helps reduce internal heat. The detailed explanation is as follows:

Oolong tea is a semi-fermented tea containing nutrients such as protein, amino acids, vitamins, organic acids, carbohydrates, and tea polyphenols. It has various benefits including refreshing the mind, aiding digestion, promoting saliva secretion and urination, detoxifying, preventing heatstroke, and antibacterial and anti-inflammatory effects. Due to its fermentation process, oolong tea is neither considered hot nor cold in nature. It possesses properties that clear heat, detoxify, generate body fluids, and quench thirst, thereby helping to balance excessive internal heat in the body. Additionally, the tea polyphenols in oolong tea can help neutralize free radicals, reduce cellular damage, lower inflammation levels, and alleviate symptoms of "heatiness" such as oral ulcers and dry stools. Therefore, oolong tea can effectively reduce internal heat.

Although oolong tea offers many health benefits, it is recommended to consume it in moderation to avoid potential adverse effects such as disrupted sleep, impaired calcium absorption, or gastrointestinal discomfort.
