1. It is forbidden to drink the first tea: because the tea is polluted by pesticides and other harmful substances during the cultivation and processing, there is always a certain residue on the surface of the tea.
2. Avoid drinking tea on an empty stomach: Drinking tea on an empty stomach can dilute gastric juice and reduce digestive function, causing a large amount of bad ingredients in tea to enter the bloodstream, causing symptoms such as dizziness, palpitation, and weakness of limbs.
3. Drink less new tea: Because new tea has a short storage time, it contains more unoxidized polyphenols, aldehydes and alcohols, which have a strong stimulating effect on human gastrointestinal mucosa and easily induce stomach problems. New tea that has been stored for less than half a month should be avoided.
4. People with cold stomach should not drink too much. Excessive amount will cause gastrointestinal discomfort. People with neurasthenia and insomnia should not drink tea before going to bed. Women who are breastfeeding should also drink less tea. Tea has astringent effects on milk.
5, avoid taking medicine with green tea, avoid drinking overnight tea. Tannic acid in green tea will combine with many drugs to form precipitation, hinder absorption and affect drug efficacy.
