H. pylori and chronic gastritis

Helicobacter pylori infection and chronic gastritis represent a convergence of bacterial pathology and digestive tissue depletion. Conventional treatment relies on triple-antibiotic therapy — typically proton pump inhibitors, clarithromycin, and amoxicillin or metronidazole — which eradicate the bacteria but often leave the Stomach and Spleen function severely compromised. Patients report persistent bloating, poor appetite, loose stools, and slow recovery of digestive capacity even after successful bacterial clearance.

Classical Chinese medicine recognizes gastritis and H. pylori as expressions of deeper digestive disharmony. The infection itself may be opportunistic — taking root when the Stomach’s protective barrier (its Yin reserve and mucosal integrity) has been depleted by chronic stress, irregular eating, or prolonged Liver constraint. This explains why some patients are susceptible to reinfection, despite successful eradication, and why conventional treatment alone often fails to restore true health.

Three classical patterns in H. pylori and gastritis

Stomach Yin Deficiency (胃阴虚 wèi yīn xū)

Chronic inflammation erodes the Stomach’s fluid reserve. Patients experience burning pain between meals, a dry mouth with little thirst, a tendency toward constipation, and a thin or peeled tongue with scanty saliva. The Stomach acid becomes caustic without the cooling, nourishing fluids that normally protect the mucosal lining. Pain is often worse with hot or spicy food and improves temporarily with cool fluids or light meals.

Why this matters: Stomach Yin deficiency is the hallmark of chronic gastritis and peptic ulcer disease. H. pylori thrives in this depleted, inflamed environment. Treatment must cool and nourish the Stomach fluid (增液法 zēng yè fǎ) while simultaneously addressing the infection itself.

Liver Invading Stomach (肝气犯胃 gānqì fàn wèi)

Emotional stress and constraint cause the Liver (whose qi moves freely) to invade the Stomach’s orderly, descending function. Patients report sharp, cramping pain that comes and goes with mood, stress-triggered flares, and a sensation of fullness or pressure in the epigastrium. Appetite is variable; stools may alternate between loose and hard.

Why this matters: Stress does not directly cause H. pylori infection, but Liver constraint and qi stagnation create the inflammatory cascade that allows bacteria to colonize and weakens the immune surveillance that would otherwise contain them. Many patients report that their gastritis began or worsened after a period of sustained stress.

Damp-Heat in the Stomach (湿热困脾胃 shīrè kùn píwèi)

Acute gastritis and active H. pylori infection often present with Damp-Heat — mucosal inflammation (Heat) trapped within and dampening Stomach function. Patients experience nausea, heavy epigastric distension, loose or urgent stools, and a coating on the tongue that is yellow and thick. Symptom flares follow rich, greasy, or fermented foods.

Why this matters: H. pylori is a Damp-Heat pathogen from the CCM perspective. Clearing Heat and drying Dampness are essential during the acute infection phase and should be layered into herbal protocols alongside antibiotic therapy to improve eradication rates.

Why antibiotic monotherapy falls short

Triple antibiotic therapy succeeds in killing H. pylori bacteria but disrupts the Stomach and Spleen’s beneficial microbial flora and depletes their qi and Yin. Patients often emerge from treatment with:

• Weak digestion: The Spleen’s qi is exhausted from processing antibiotics; appetite and nutrient absorption remain poor for weeks or months.
• Poor gut barrier repair: The Stomach’s Yin remains depleted; mucosal healing stalls without active nourishment and cooling.
• Dysbiosis and reinfection risk: The microbial environment is hostile to beneficial flora, allowing pathogens to colonize more easily if the barrier is still weak.
• Food sensitivities: Prolonged antibiotic exposure leaves the intestinal lining compromised; patients develop new intolerances to foods they previously tolerated.

Herbal medicine, used before, during, and after antibiotic treatment, addresses all three of these gaps: supporting immune function and Stomach barrier integrity during bacterial clearance, nourishing Yin and cooling Heat to accelerate mucosal healing, and restoring healthy microbial balance to prevent reinfection.

What treatment looks like

Phase 1: Pre-treatment preparation (1–2 weeks before antibiotics)

We begin with herbs that cool residual Heat, dry Dampness, and begin nourishing Stomach Yin. Formulas in this phase typically include cooling, demulcent herbs such as Ophiopogon japonicus (麦冬 mài dōng) and Dendrobium officinale (石斛 shí hú) alongside carminatives and Spleen-supportive herbs. The goal is to strengthen the Stomach barrier and improve immune readiness before antibiotics begin.

Phase 2: During antibiotic therapy (10–14 days)

The herbal formula remains gentle but supportive: we shift toward herbs that protect the Spleen and Stomach from antibiotic depletion while the antibiotics do their work. Formulas emphasize digestive herbs that prevent dysbiosis (such as Oryza sativa germinatus / 谷芽 gǔ yá and Hordeum vulgare germinatus / 麦芽 mài yá) and Spleen tonics (Atractylodes macrocephala / 白术 bái zhú, Poria cocos / 茯苓 fú líng).

Phase 3: Post-eradication healing (6–8 weeks)

Once antibiotics are complete, we shift into active Stomach Yin nourishment. This is the critical window for barrier repair. Formulas emphasize cooling, moistening herbs that restore the Stomach’s protective fluids. Common herbs include Ophiopogon, Dendrobium, Angelica sinensis (当归 dāng guī) for blood nourishment, and Glycyrrhiza glabra (甘草 gān cǎo) for protective, demulcent action. We may add circulation-promoting herbs if there is blood stagnation from the inflammation.

During this phase, dietary guidance is equally important: warm foods only, regular meal timing to support Spleen qi, and elimination of trigger foods (alcohol, caffeine, fried foods, heavy proteins) until healing is well established.

Phase 4: Long-term prevention (3–6 months onward)

For patients with a history of Liver constraint or high stress, we may include a longer course of Liver constraint-resolving herbs (such as Bupleurum falcatum / 柴胡 chái hú or Citrus × aurantium / 香附 xiāng fù) alongside continued Stomach Yin support. The goal is to prevent the stagnation that allows H. pylori to return and to establish a more robust digestive baseline.

Diagnostic testing and follow-up

We recommend retesting for H. pylori 4–6 weeks after completing antibiotics to confirm eradication. Herbal support should begin immediately after antibiotics finish (do not delay), and should continue for at least 6–8 weeks, with follow-up assessment to track symptom resolution and Stomach barrier healing.

Some patients benefit from a subsequent stool analysis to assess microbial recovery. This helps us refine the herbal protocol if dysbiosis persists beyond the expected window.
