Precautions:

Never drink tea on an empty stomach: drinking tea on an empty stomach will dilute gastric juice, reduce digestive function, and may also lead to drunk tea, leading to dizziness, palpitation, limb weakness and other symptoms.

People with a cold stomach are forbidden to drink tea: Lipton green tea is cold and cool, and drinking too much may have adverse effects on the gastrointestinal tract. People with neurasthenia and insomnia should not drink green tea before going to bed, and lactating women should also drink less green tea, because green tea has a astringent effect on milk.
