Gastric irritant: Many chemicals in tea can stimulate or irritate the lining of your stomach, including caffeine. other elements such as tannic acid also can be irritating and cause nausea or cramps in susceptible people, or if you already have stomach irritation (gastritis), tea can make it worse. Try taking a liquid antacid if it occurs again.
