If you enjoy occasionally sipping a cup of green tea to make you feel a little more alert during a dull afternoon at work, don't expect that you'll soon need to have a bowel movement. Although caffeine can promote bowel activity, tea doesn't typically have a laxative effect on your digestive system.
Tea Shouldn't Make You Go
Caffeinated coffee can serve as a valuable laxative, even if you drink only a moderate amount. Tea, however, doesn't have the same laxative quality, according to the One Medical Group. Green tea contains significantly less caffeine than coffee. A cup of green tea has between 14 and 60 milligrams of caffeine, which is milder than the 100 milligrams of caffeine in a standard cup of coffee. Green tea is a diuretic, however, which means it might make you urinate more than usual.
