Taboos for drinking tea:

1, it is forbidden to drink tea all over the body: because tea is polluted by harmful substances such as pesticides during planting and processing, there will always be some residues on the surface of tea.

2, avoid drinking tea on an empty stomach: drinking tea on an empty stomach will dilute gastric juice and reduce digestive function, resulting in a large number of bad ingredients in tea entering the blood, causing dizziness, palpitation, limb weakness and other symptoms.

3, drink less new tea: because the new tea has a short storage time, it contains more unoxidized polyphenols, aldehydes and alcohols, which has a strong stimulating effect on the human gastrointestinal mucosa and is easy to induce stomach problems. New tea stored for less than half a month should be avoided.

4, people with cold stomach should not drink too much, too much will cause gastrointestinal discomfort. People with neurasthenia and insomnia should not drink tea before going to bed, and lactating women should also drink less tea. Tea has astringent effect on milk.

5, avoid taking medicine with green tea, avoid drinking overnight tea. Tannic acid in green tea will combine with many drugs to produce precipitation, which will hinder absorption and affect the efficacy.
