Ginger is excellent at helping with digestion issues, especially if you’re feeling nauseous. But it does have some side effects that you should be aware of. It has to be taken in large doses for these to occur, but they’re still something you should be aware of beforehand. The most common side effects include diarrhea, heartburn, and bloating. If you suffer from gallstones, ulcers, or IBS, then you should avoid large amounts of fresh ginger as it can aggravate your symptoms. You should especially avoid overeating ginger if you also suffer from a bleeding disorder since it works as a natural anticoagulant.
