Herbs are usually safe, but they aren’t right for everyone. They can interfere with medications you’re taking, and you could be allergic. Talk to your doctor before you take herbal supplements to make sure they’re safe for you.  Remind your doctor of the medications and supplements you’re already taking. If you are pregnant, do not take any herbal supplements before you talk to your doctor. When you take herbal supplements, always follow your doctor's dosing instructions as well as the manufacturer's instructions about dosing. Occasional heartburn typically isn’t anything to worry about. However, chronic heartburn may be a problem. Over time, chronic heartburn can lead to complications, so it’s best to visit your doctor. They’ll figure out what’s causing your heartburn and offer you treatment options.  Symptoms of heartburn include a burning or irritating sensation in the middle of your chest, a sour taste in your mouth, burping or hiccups that won’t stop, dry coughs, nausea, stomach bloating, dark or black stools, feeling like food is stuck in your throat, and pain that gets worse when you bend over or lie down. Your doctor will likely recommend you try over-the-counter (OTC) heartburn treatments if you haven’t already. These can neutralize acid or reduce your acid production.  Additionally, they’ll probably suggest lifestyle changes. If this doesn’t work, they’ll probably prescribe a medication for you. Chronic heartburn can turn into GastroEsophageal Reflux Disease (GERD), which can cause serious ulcers that may cause internal bleeding. GERD can also increase your risk for certain medical conditions, so it’s important to get treatment if you need it. Try not to worry, but these are always considered emergency symptoms. It’s especially important that you get treatment if you’re also experiencing pain in your arm or jaw, which could indicate a heart attack. Visit an emergency room or call for help if you have these serious symptoms.Heartburn can cause extreme symptoms in some cases. However, it’s always best to be safe and make sure you're okay.

Summary:
Check with your doctor before using herbal remedies. See your doctor if you have heartburn at least twice a week. Get emergency medical care for chest pain and difficulty breathing.
