If you’ve ever dealt with stomach ulcers, you know how brutal the symptoms can be—sharp stabbing stomach pain, burning emptiness especially on an empty stomach, night-time stomach flares, slow digestion, and even mild bloating that just won’t go away. As a herbal pharmacist, I recommend licorice root (especially DGL) as one of the most evidence-backed natural supportive herbs for stomach ulcer recovery.
A quick, clear distinction most people miss: Gastritis is general stomach lining inflammation, while stomach ulcers are open, tiny wounds on the stomach wall. These raw wounds get constantly irritated by stomach acid, which is why ulcer pain feels way sharper and more persistent than regular gastritis discomfort. Licorice works uniquely well to heal these open mucosal wounds.

Why Stomach Ulcers Are So Hard to Heal
Stomach ulcers form when the stomach’s protective mucosal barrier is completely broken down, leaving raw, exposed stomach tissue vulnerable to strong digestive acid and enzymes.
Common culprits include long-term NSAID painkillers, heavy alcohol consumption, chronic stress, irregular eating, and H. pylori bacterial infection. The biggest problem with ulcers is that antacids and acid blockers only temporarily reduce acid—they don’t repair the open wound. That’s why many people experience repeated ulcer flares.
To fully recover, your stomach needs two things: less acid irritation and steady mucosal tissue repair—and that’s exactly what licorice delivers.
How Licorice Root Helps Heal Stomach Ulcers (Pharmacist Breakdown)
Licorice root is a classic mucosal restorative herb in both Western herbal medicine and TCM. It doesn’t just soothe pain temporarily; it actively accelerates ulcer wound healing through four core mechanisms:
1. Rebuilds a thick protective mucus layer over ulcer wounds
This is licorice’s biggest advantage for ulcers. It stimulates the stomach to secrete thick, protective gastric mucus that directly covers open ulcer wounds. This natural barrier blocks stomach acid from touching the raw tissue, instantly reducing stabbing pain and burning sensations, and creates a stable environment for wounds to heal.
2. Reduces severe gastric inflammation
Ulcers always come with intense local inflammation around the wound area. Licorice’s active flavonoids gently calm excessive stomach inflammation, easing swelling, soreness, and persistent post-meal discomfort that slows down recovery.
3. Accelerates mucosal wound regeneration
Unlike regular gut-soothing herbs, licorice promotes cell repair and tissue regrowth on damaged stomach lining. It helps shallow and mild stomach ulcers close faster and prevents small ulcers from turning into deeper, chronic wounds.
4. Inhibits H. pylori overgrowth (key for recurring ulcers)
Most recurrent stomach ulcers are linked to H. pylori infection. Licorice has natural mild antibacterial effects that suppress excessive H. pylori activity. While it cannot replace antibiotic treatment for positive infections, it drastically reduces the chance of ulcers coming back after recovery.
Regular Licorice vs DGL Licorice for Ulcer Healing
For ulcer repair, DGL (Deglycyrrhizinated Licorice) is non-negotiable for long-term use.
Standard raw licorice root and licorice tea contain glycyrrhizin. Long-term daily intake for ulcer recovery (which takes weeks) can cause side effects like high blood pressure, water retention, and low potassium.
DGL removes glycyrrhizin entirely while preserving all the ulcer-healing, mucosa-repairing compounds. It is safe, gentle, and specifically formulated for long-term stomach lining repair—perfect for ulcer recovery cycles.
Proper DGL Usage Routine for Stomach Ulcers
Ulcer healing relies on correct timing more than dosage. Follow this pharmacist-recommended routine for best results:
Chew DGL tablets fully 20–30 minutes before every meal.
Do not swallow whole. Thorough chewing lets the active ingredients coat the ulcer wounds and stomach lining completely before food and acid secretion kick in.
For empty-stomach ulcer pain flares: Chew one serving on an empty stomach to form an emergency protective coating and relieve sharp pain fast.
Recovery cycle: Mild stomach ulcers require 4–8 weeks of consistent daily DGL use for full wound closure. Chronic shallow ulcers may need 8–12 weeks of steady repair.
Who Must Avoid Licorice & DGL
Even natural healing herbs have contraindications. Avoid regular use if you have:
- High blood pressure or hypertension
- Heart disease, arrhythmia or palpitations
- Kidney impairment or kidney disease
- Persistent low potassium levels
- Pregnancy or breastfeeding
- Prescription blood pressure drugs, diuretics or steroid medications
FAQs (Stomach Ulcer & Licorice Most Common Questions)
Q: Can DGL cure stomach ulcers completely?
A: It can fully heal mild, shallow stomach ulcers and prevent recurrence. For moderate or deep ulcers, or H. pylori-positive ulcers, DGL works as a powerful supportive remedy to speed up medical recovery, not a standalone replacement for prescription treatment.
Q: How fast does DGL relieve ulcer pain?
A: Most people feel obvious pain relief within 10–20 minutes after chewing DGL, thanks to the instant mucosal coating effect. Full wound healing takes several weeks of consistent use.
Q: Can I drink licorice tea daily for stomach ulcers?
A: No. Daily regular licorice tea carries cardiovascular and electrolyte risks. Always choose purified DGL supplements for long-term ulcer repair.
Q: Is DGL better than acid blockers for ulcers?
A: Acid blockers stop acid production to let wounds heal, while DGL actively repairs the stomach lining. Combining both often delivers the fastest ulcer recovery—symptom relief + root healing.
Q: Can DGL prevent ulcers from coming back?
A: Yes. By rebuilding a strong, intact stomach mucosal barrier and balancing mild H. pylori activity, DGL drastically reduces ulcer recurrence caused by weak gut lining and inflammation.
Final Herbal Pharmacist Verdict
When it comes to stomach ulcers, the biggest mistake people make is only chasing quick acid relief. Ulcers need wound repair, and DGL licorice is one of the safest, most effective natural tools for rebuilding damaged stomach tissue.
If you struggle with recurring mild stomach ulcers, empty-stomach pain, or slow ulcer recovery, consistent DGL use is hands down one of the best natural additions to your daily gut healing routine.
