Does Pu'er tea cause internal heat or reduce internal heat?

Pu'er tea is categorized into raw (sheng) tea and ripe (shu) tea. Raw tea is cooling in nature and helps to reduce internal heat, possessing effects of clearing heat, relieving fire toxicity, and alleviating summerheat. Ripe tea is warming in nature, and excessive consumption may cause heatiness (excess internal heat). Components in Pu'er tea, such as theobromine and anthocyanins, help refresh the mind, enhance alertness, promote metabolism, and aid in reducing internal heat. However, excessive consumption or improper methods of tea consumption may negatively affect the body, potentially causing symptoms of heatiness. For individuals prone to heatiness, it is recommended to consume raw Pu'er tea in moderation to achieve the effect of reducing internal heat. Although ripe Pu'er tea can be beneficial for the stomach, its consumption should be controlled to avoid inducing heatiness. The effect of Pu'er tea in either causing or reducing heatiness depends on its type and method of consumption. Drinking raw Pu'er tea in moderation helps reduce internal heat, whereas ripe Pu'er tea should be consumed with caution.
