Can drinking lotus leaf tea cause diarrhea?
"Diarrhea" usually refers to diarrhea. Under normal circumstances, drinking lotus leaf tea does not cause diarrhea, but it may lead to diarrhea when consumed in excess. The detailed analysis is as follows:

Lotus leaf tea has certain medicinal value. Components such as lotus alkaloids contained in it can promote intestinal peristalsis and diuresis. When consumed in moderate amounts, lotus leaf tea generally does not cause diarrhea; on the contrary, it benefits health and helps improve symptoms such as indigestion and edema.
Lotus leaf tea is a cooling beverage and contains dietary fiber. For individuals with spleen and stomach deficiency-cold, drinking lotus leaf tea may damage the spleen and stomach, thus causing diarrhea. In addition, excessive consumption of lotus leaf tea may exceed the body's tolerance, overly stimulate the intestines, and impair normal digestive and absorptive functions of the gut, thereby triggering diarrhea.
When drinking lotus leaf tea, it's important to control the amount and avoid consuming too much at once. People who inherently have weak gastrointestinal function or are prone to diarrhea should consume lotus leaf tea cautiously. It is also advisable to avoid drinking lotus leaf tea on an empty stomach; instead, it can be consumed between half an hour to two hours after a meal.
