Acid reflux can indicate serious underlying conditions — please see a doctor if symptoms persist or worsen.
If you’ve been on a proton pump inhibitor for years and still reaching for antacids after every meal, you’re not alone. Millions of people manage acid reflux and GERD with medication — and many of them quietly wonder whether there’s anything else that might help.
There is. A handful of herbal remedies have real evidence behind them for acid reflux. But several popular recommendations don’t — and one common suggestion can actually make things worse if you use the wrong form.
Here’s what the evidence actually shows, with doses and the caveats that matter.
What actually causes acid reflux?
Acid reflux happens when stomach acid flows back into the esophagus. The lower esophageal sphincter (LES) — the muscular valve between your stomach and esophagus — is supposed to keep acid where it belongs. When it relaxes or weakens at the wrong moment, acid escapes upward and burns the esophageal lining.
Common triggers include fatty or fried foods, coffee, alcohol, chocolate, large meals, eating close to bedtime, excess body weight, and stress. Some medications — including NSAIDs, certain blood pressure drugs, and tricyclic antidepressants — also relax the LES or irritate the esophagus directly.
Herbal remedies don’t fix the underlying cause. What several of them do is protect the esophageal lining, reduce inflammation, or support more efficient stomach emptying. That’s where they can genuinely help — and why they work best alongside dietary changes, not instead of them.
5 herbal remedies for acid reflux — what the evidence shows
DGL Licorice — the mucosal protector (but only the right form)
DGL stands for deglycyrrhizinated licorice — licorice root with the compound glycyrrhizin removed. That distinction matters enormously. Regular licorice raises blood pressure and causes fluid retention. DGL does neither.
What DGL does is stimulate the body’s production of protective mucus in the stomach and esophageal lining. Rather than suppressing acid production, it works with your body’s defenses to reduce how much damage acid does on contact.
A 30-day controlled trial using a standardised licorice root extract (GutGard) found a 55% reduction in heartburn and GERD symptom scores compared to 19% in the placebo group — a clinically meaningful difference. Earlier research on DGL tablets showed similar mucosal-protective effects in peptic ulcer disease. Pharmacological studies confirm the mechanism: DGL increases secretion of mucin glycoproteins that form the protective mucosal barrier.
Dose: 380–760 mg chewable DGL tablets, taken 20 minutes before meals, two to three times daily. Chewable tablets matter here — the saliva interaction appears to trigger the mucosal response.
Safety note: DGL is considered safe for long-term use. Regular licorice is not — it raises blood pressure, depletes potassium, and interacts with antihypertensives, diuretics, and digoxin. Always confirm your product explicitly says DGL or deglycyrrhizinated licorice.
Slippery Elm — coating and calming the esophagus
Slippery elm bark contains mucilage — a substance that becomes thick and gel-like when mixed with water. This gel coats the lining of the esophagus and stomach, forming a physical barrier between tissue and stomach acid. Think of it as an internal soothing layer.
It doesn’t reduce acid production, but it reduces how much damage acid does on contact. This makes it particularly useful for people with the burning sensation of esophagitis — inflammation of the esophageal lining caused by repeated acid exposure.
Clinical trial evidence is limited. Most support comes from traditional use and pharmacological understanding of its demulcent mechanism rather than large randomised trials. That said, its safety profile is excellent and it has been used safely for centuries. As a first-line herbal support alongside dietary changes, it’s a reasonable starting point.
Dose: 1–2 teaspoons of powdered bark mixed in warm water, 30 minutes before meals. The warm drink form tends to be most effective for esophageal symptoms specifically, since it physically coats the esophagus on the way down. Capsules and lozenges are also available.
Safety: Slippery elm can slow the absorption of medications taken at the same time — maintain a 2-hour gap between slippery elm and other medications. Avoid in medicinal quantities during pregnancy.
Aloe Vera Juice — cooling esophageal inflammation
Aloe vera juice has anti-inflammatory properties that may reduce irritation in the esophagus. A 2015 meta-analysis by Panahi and colleagues reviewed aloe vera’s effects on GERD and found it to be a safe, effective, and well-tolerated option for reducing the frequency of GERD symptoms — including heartburn, food regurgitation, belching, and nausea — compared to placebo.
The anti-inflammatory effect appears to work by reducing cytokine activity in the esophageal lining — the same inflammatory pathway involved in esophagitis. This is why aloe vera shows most benefit for people with frequent, irritating reflux rather than occasional mild heartburn.
Dose: 10–30 mL of processed aloe vera juice (inner leaf only, decolorized, with anthraquinones removed) before meals. The “inner leaf” or “decolorized” label is critical — whole leaf aloe contains anthraquinones that act as powerful laxatives and are not safe for ongoing use.
Safety: Inner leaf/decolorized aloe vera is safe at typical amounts. Whole-leaf preparations are not suitable for daily use. Check labels carefully. Avoid during pregnancy. Aloe may have mild blood-thinning properties — discuss with your doctor if you take anticoagulants.
Chamomile Tea — working on the stress-reflux connection
Stress is one of the most underestimated drivers of acid reflux. It doesn’t cause reflux directly, but it alters gut motility, increases gastric acid secretion, and reduces esophageal pain thresholds — meaning the same amount of acid exposure causes more discomfort when you’re stressed.
Chamomile works on both fronts. Its anti-inflammatory compounds (particularly apigenin) help calm esophageal inflammation, while its well-documented anxiolytic effects address the stress-driven component of reflux. It also has mild antispasmodic properties that may help modulate LES function.
There’s no large clinical trial specifically on chamomile for GERD, but its anti-inflammatory and antispasmodic actions are established across multiple pharmacological studies. As a daily evening practice — particularly if your reflux worsens under pressure — it’s low-risk and worth building in.
If chamomile is part of your digestive support routine, our guide to the best herbal teas for bloating and constipation covers how to prepare chamomile and other digestive herbs most effectively.
Dose: 1–2 cups daily, 20–30 minutes before meals or in the evening. Use good quality dried chamomile flowers steeped for 5–7 minutes.
Safety: Avoid if allergic to ragweed or plants in the Asteraceae family. Can interact with warfarin at high doses. Do not use in medicinal quantities during pregnancy.
Ginger — genuinely useful, but the dose changes everything
Ginger is one of the most evidence-backed herbs for digestive complaints. But its relationship with acid reflux is more complicated than most articles admit. At low doses, ginger acts as a prokinetic — it helps the stomach empty more efficiently. A faster-emptying stomach means less pressure build-up and fewer opportunities for acid to escape upward. This is genuinely helpful for reflux.
At higher doses, however, ginger can relax the LES — the very valve you’re trying to keep closed — and worsen reflux. The dose matters considerably more with ginger than with most other digestive herbs.
For a detailed guide on ginger’s digestive applications and safe preparation, see our article on how to use ginger for nausea and bloating.
Dose for reflux: One quarter to one half teaspoon of freshly grated ginger in warm water, 20–30 minutes before meals. A gentle ginger tea at this amount is appropriate. High-dose ginger supplements (1,000 mg or more) are counterproductive for acid reflux specifically.
Safety: Safe at culinary doses. At higher doses, ginger has antiplatelet effects that interact with blood-thinning medications. Avoid more than 1 g/day during pregnancy. Stop 2 weeks before surgery.
How to use these remedies in practice
Herbal remedies for acid reflux work best as part of a consistent daily routine — not as rescue medications after reflux has already struck. The protective herbs (slippery elm, aloe vera, DGL licorice) need to be taken before meals, when acid production is about to increase.
A practical starting protocol: take chewable DGL or a warm slippery elm drink 20–30 minutes before your two main meals. Drink chamomile tea in the evening, especially on high-stress days. Use low-dose ginger tea before meals if your stomach tends to feel heavy and slow after eating.
Dietary changes remain the foundation. Avoid eating within 3 hours of bedtime, reduce portion sizes, identify your personal triggers, and consider elevating the head of your bed 15–20 cm if night reflux disrupts your sleep.
Drug interactions and what to avoid
If you take any of the following medications, discuss herbal additions with your doctor or pharmacist before starting:
- Regular licorice (not DGL) interacts with antihypertensives, diuretics (depletes potassium), and digoxin. DGL does not carry these risks — but always confirm your product says DGL specifically.
- Slippery elm reduces absorption of medications taken at the same time. Maintain a 2-hour gap between slippery elm and other drugs.
- Ginger at higher doses has antiplatelet effects and can potentiate warfarin, aspirin, and other blood thinners.
- Chamomile may potentiate warfarin activity at high intake.
If you currently take PPIs (omeprazole, lansoprazole, esomeprazole) or H2 blockers (famotidine), do not stop them without medical guidance. Herbal remedies are complementary to prescribed acid reflux treatment — not replacements for it.
When to see a doctor — don’t ignore these symptoms
Occasional heartburn is reasonable to manage independently with herbal support and dietary changes. But acid reflux that is frequent, severe, or not improving warrants a medical evaluation. Untreated chronic GERD can lead to esophagitis, esophageal stricture, and — in some people — Barrett’s esophagus, a condition where changes to the esophageal lining increase the long-term risk of esophageal cancer.
See a doctor promptly if you experience any of the following:
- Difficulty swallowing (dysphagia) or pain when swallowing
- Unexplained weight loss
- Persistent vomiting, or blood in vomit
- Chest pain — always rule out cardiac causes first
- Symptoms not improving after 2–4 weeks of consistent herbal and dietary management
- Night reflux that repeatedly wakes you from sleep
- Chronic hoarseness or cough that appears linked to reflux
These are alarm symptoms. They don’t mean herbal support can’t still play a role in your care — they mean you need a diagnosis before managing independently.
