Caffeine (including caffeine from green tea) can increase blood pressure in people taking propranolol and metoprolol (drugs used to treat high blood pressure and heart disease).
3. Blood-thinning drugs
People who are taking warfarin (a blood-thinning medication) should not take it with tea. Because green tea contains vitamin K, it can make warfarin ineffective. Meanwhile, you should not mix green tea and aspirin because they prevent platelets from clotting. Using both together can increase the risk of bleeding.
4. Ephedrine
When taken with ephedrine, green tea can cause agitation, tremors, insomnia, and weight loss.
