Morning is suitable for drinking black tea:

After sleeping through the night, the body is often in a relatively static state. Drinking black tea can promote blood circulation while dispelling cold from the body and ensuring adequate blood supply to the brain.

Black tea has mild properties and can be brewed every morning after waking up, consumed after breakfast, or mixed with an appropriate amount of milk. It's important to note that you should never drink tea on an empty stomach, as tea leaves contain caffeine. Drinking on an empty stomach can cause excessive caffeine absorption in the intestines, leading to adverse reactions such as palpitations and frequent urination. Over time, this can also affect the body's absorption of vitamin B.

Afternoon is suitable for drinking oolong tea or green tea:

Typically, the body experiences vigorous liver fire around noon. Drinking green tea or oolong tea at this time can alleviate this symptom.

Oolong tea (such as Tieguanyin) has sweet and cool properties, enters the liver meridian, can clear liver and gallbladder heat, resolve liver toxins, and is rich in vitamin E, which can resist aging; Green tea enters the kidney meridian, promotes diuresis and removes turbidity, ensuring smooth urination. Additionally, green tea contains extremely high levels of tea polyphenols, providing excellent antioxidant and anti-inflammatory effects.
