It's 4th day my stomach is heavy and a bit crampy. i never drank tea, but i'm drinking half cup in the morning just to poop. no gas discharge, a little bit bloating, very slight sense of nausea, appetite is good and stool is fine. what should i do?

Your symptoms are nonspecific at this time. They could be from some intolerance of a meal you ate a few days ago or you could be fighting an intestinal viral infection. . Make the tea weak but hot enough to break down gas & move it down and out the rectum. See a physician if there's persistent abdominal discomfort especially with associated tenderness or vomiting.
