Several natural remedies can relieve heartburn quickly, with baking soda, ginger, and chewing gum among the best-supported options. Some work by neutralizing stomach acid directly, others by speeding up digestion or protecting the lining of your esophagus. The right choice depends on whether you need fast relief from an occasional flare or a longer-term strategy for recurring symptoms.
Baking Soda for Fast Relief
Baking soda (sodium bicarbonate) is the quickest natural antacid most people already have at home. It neutralizes stomach acid on contact, and relief typically begins within minutes. The standard dose is half a teaspoon dissolved in a full glass of cold water every two hours as needed, with a maximum of five teaspoons per day.
This is a short-term fix, not a daily habit. Baking soda contains a significant amount of sodium, which matters if you have high blood pressure or are watching your salt intake. It can also cause gas and bloating. Think of it as the equivalent of a store-bought antacid tablet you happen to have in your pantry, not a replacement for figuring out why your heartburn keeps coming back.
Ginger Speeds Up Digestion
Heartburn often worsens when food sits in your stomach too long, giving acid more opportunity to splash upward. Ginger directly addresses this. In a clinical study, 1.2 grams of ginger root powder cut the time it took for the stomach to empty by roughly 25%, from about 16 minutes (half-emptying time) with a placebo down to about 12 minutes with ginger. Faster emptying means less acid pooling and less pressure pushing contents toward your esophagus.
The exact mechanism isn’t fully understood, but ginger appears to enhance the contractions of the lower stomach that push food into the small intestine, possibly by interacting with serotonin receptors in the gut. You can get ginger through capsules (1,200 mg of ginger root powder was the study dose), freshly grated ginger steeped in hot water as tea, or even candied ginger chewed after a meal. Avoid ginger ale, which is mostly sugar and contains very little actual ginger.
DGL Licorice Protects Your Lining
Deglycyrrhizinated licorice, usually sold as DGL, takes a completely different approach from acid neutralizers. Instead of reducing or buffering acid, it strengthens the protective barrier that lines your esophagus and stomach. DGL increases blood flow to damaged tissue, boosts the number of mucus-producing cells, increases the amount of mucus those cells generate, and extends the lifespan of the cells that make up the lining itself.
The active compounds responsible are flavonoids. In head-to-head studies against common over-the-counter acid reducers, DGL performed as well or better for healing peptic ulcers, both in the short term and for maintenance. The typical dose in studies was 760 mg taken three times a day between meals, usually as chewable tablets. The “deglycyrrhizinated” part matters: regular licorice root contains glycyrrhizin, which can raise blood pressure and deplete potassium with regular use. DGL has that compound removed, making it safer for ongoing use.
Slippery Elm and Marshmallow Root
Both of these herbs belong to a category called demulcents, meaning they produce a thick, slippery gel when mixed with water. This gel physically coats the esophagus and stomach lining, creating a temporary barrier between your tissue and stomach acid. Slippery elm is the more widely studied of the two. Its mucilage soothes inflamed tissue in the digestive tract, reduces the sensation of burning, and may stimulate additional mucus production in the intestines.
You’ll find slippery elm as lozenges, powders you mix into water, or capsules. The coating effect is most pronounced when the herb makes direct contact with your throat and esophagus, so lozenges or a thick tea tend to work better than swallowing a capsule. The relief is temporary, lasting as long as the coating stays in place, but it can be helpful right before bed when lying flat tends to worsen symptoms.
Chewing Gum After Meals
This one sounds too simple, but the physiology behind it is solid. Chewing gum stimulates a significant increase in saliva production, and saliva is naturally rich in bicarbonate, the same compound that makes baking soda work. When your saliva flow rate increases, the bicarbonate concentration in it rises substantially, turning each swallow into a small wave of natural antacid washing down your esophagus.
Sugar-free gum is the better choice since sugar can feed bacteria and contribute to other issues. Some gums are formulated with added sodium bicarbonate (about 4% by weight), which boosts the buffering effect even further. Chewing for 20 to 30 minutes after a meal helps clear residual acid from the esophagus at exactly the time heartburn is most likely to strike.
Foods That Help Buffer Acid
Bananas are one of the most accessible food-based remedies. They’re rich in potassium, which helps regulate acid levels, and their soluble fiber absorbs stomach acid. Ripe bananas have a pH between 5.5 and 6.0, making them mildly acidic on their own but functionally helpful because of the fiber’s buffering action. A banana before bed or after a heavy meal can take the edge off.
Oatmeal works through a similar mechanism. Its soluble fiber forms a gel in the stomach that buffers acid and can ease reflux symptoms. Other helpful foods include melons (pH 6.0 to 6.5) and green vegetables (pH 6.0 to 7.0). The broader pattern is straightforward: whole, unprocessed, non-spicy foods that are low in fat tend to cause less reflux than fried, acidic, or heavily seasoned meals.
What About Apple Cider Vinegar?
Despite its popularity on wellness blogs, apple cider vinegar has no published clinical evidence supporting its use for heartburn. Harvard Health Publishing reviewed the available literature and found zero studies in medical journals addressing its effectiveness or safety for acid reflux. The theory behind it, that heartburn is caused by too little stomach acid rather than too much, is not supported by mainstream gastroenterology. Adding vinegar (which is acetic acid) to an already irritated esophagus could plausibly make things worse, not better.
What About Melatonin?
Melatonin, best known as a sleep supplement, has several properties that could theoretically help with reflux. It inhibits stomach acid secretion, stimulates the release of bicarbonate in the small intestine, and increases the release of gastrin, a hormone that tightens the muscular valve between your esophagus and stomach. Animal studies have shown these effects clearly, though human research is still catching up. If you already take melatonin for sleep and notice your nighttime heartburn improves, there may be a real connection.
When Natural Remedies Aren’t Enough
Occasional heartburn after a big meal or a glass of wine is normal, and natural remedies handle it well. But certain symptoms signal something more serious that home remedies won’t address. These include difficulty swallowing, pain while swallowing, vomiting (especially with blood), unintentional weight loss, loss of appetite, or any sign of gastrointestinal bleeding like dark or bloody stools. These are considered alarm symptoms that warrant prompt medical evaluation, because they can indicate strictures, significant esophageal damage, or other conditions that need direct diagnosis.
Heartburn that occurs more than twice a week for several weeks, or that doesn’t respond to the strategies above, is also worth investigating further. Chronic, untreated acid reflux can damage the esophageal lining over time, and at that point, stronger interventions become genuinely important rather than optional.
