According to her, such a drink in large quantities can cause “tea intoxication.” As a result, the person who has used it is faced with an increase in blood pressure and pulse. Also, such “intoxication” can cause anxiety and physical activity in a person, followed by nausea and vomiting.
Khachirova also noted that herbs or berries are often added to tea. In the Caucasus, for example, tea with comfrey is popular. And that can be dangerous.
