Some people say drinking Pu-erh tea causes dizziness. What's the reason?

There are three possible reasons:

1. Personal constitution: inherent sensitivity to tea;

2. The tea is brewed too strong;

3. Having eaten too little; an empty stomach can also cause side effects like tea dizziness.

If you experience this, promptly adjust the tea's concentration for the best effect. Some people may also have diarrhea when drinking Pu-erh tea for the first time. This is the body's adaptation process to a new food, similar to acclimatization. It varies from person to person; not everyone will experience diarrhea. Once the body adapts, you can continue drinking. However, it is recommended to drink the second brew of Pu-erh tea or a lighter brew, as the body finds it easier to adapt.

Pu-erh is a leaf from the Camellia sinensis plant. It is bitter, cold, and has the functions of digesting meat, clearing heat, detoxifying, etc. It can relieve greasiness and the toxicity of beef and mutton, expel phlegm, promote qi descent, scrape the intestines, and promote bowel movements. The contraindication is that虚弱 (weak) individuals should avoid it.

The efficacy and禁忌 (contraindications) of Pu-erh tea are similar to those of green tea. However, you may notice it is more bitter and cold, more effective at digesting meat, relieving greasiness, and promoting bowel movements. But being more bitter and cold, it is also more damaging to the body. Therefore, the禁忌 (contraindication) is that虚弱 (weak) individuals must avoid it—meaning they should not consume it at all. Like tea, excessive consumption can damage the spleen and stomach, leading to spleen and stomach deficiency cold. This is why some people experience loosened bowels or even fatty diarrhea after drinking it, while others反而 (conversely) experience constipation due to deficiency cold constipation.
