Not all “natural” herbs are backed by real-world use or safety data—some truly help calm the gut, while others can irritate it or interact with medications. When you’re dealing with intestinal inflammation—from mild post-infectious irritation to IBS-like symptoms—it’s natural to seek gentler relief. But the key question is: which herbs actually have support from trusted health sources?
This post does not claim herbs cure Crohn’s disease or ulcerative colitis. Instead, it reviews which herbs are consistently recommended by authoritative natural health and clinical sources for symptom relief, mucosal soothing, and digestive support.
⚠️ Medical Disclaimer: These herbs are intended for mild, short-term digestive irritation or use during IBD remission under medical supervision. They are not substitutes for prescribed treatment. Always consult your doctor before starting any herbal regimen—especially if you have IBD, are pregnant, or take medications.
How We Evaluate “Evidence” for Herbs
“Evidence” here means consistent recommendation across credible, accessible health sources—not FDA approval or large-scale clinical trials (which are limited for most herbs).
We categorize support as:
- ✅ Strong Support: Recommended by Rupa Health or Tuasaude with clear mechanisms and safety notes.
- ⚠️ Traditional Use: Mentioned in home remedy guides but with minimal mechanistic detail.
- ❌ Use with Caution: Effective but carries risks in specific populations (e.g., pregnancy, IBD flares, medication use).
Top 6 Herbs for Intestinal Inflammation—Rated by Evidence
1. Peppermint (Mentha piperita)
Use: Relieves intestinal spasms, bloating, and gas.
Evidence Level: ✅ Strong Support
Peppermint soothes irritation of the intestinal walls, absorbs excess gas, and has antispasmodic properties that relieve abdominal discomfort¹. Its active compound, menthol, relaxes gastrointestinal smooth muscle².
How to use:
- Tea: Steep 6 fresh leaves or 1 tea bag in 1 cup boiling water for 5–10 minutes. Drink several times daily¹.
- Capsules: Enteric-coated peppermint oil (180–200 mg) 2–3 times/day is used in clinical IBS protocols².
Safety note: Avoid if you have GERD, hiatal hernia, or active IBD flares—it may worsen reflux or irritate narrowed segments².
2. Ginger (Zingiber officinale)
Use: Reduces nausea, inflammation, and regulates intestinal flow.
Evidence Level: ✅ Strong Support
Ginger root has antiviral and antibacterial properties that help eliminate intestinal pathogens. It also reduces inflammation of the intestinal lining, easing pain and swelling¹. Gingerols relax digestive muscles and improve motility².
How to use:
- Blend 2 cm peeled, crushed ginger with a few drops of honey and 1 glass of water. Strain and drink at least 3 times daily during acute infection¹.
Safety note: Avoid in known bowel strictures or if taking blood thinners—ginger may increase bleeding risk¹².
3. Chamomile (Matricaria chamomilla)
Use: Calms cramps, relieves gas, and reduces GI tract stimulation.
Evidence Level: ✅ Strong Support
Chamomile is rich in apigenin and other phenolic compounds that reduce gastrointestinal stimulation and relieve cramps from intestinal infections¹. It also helps dispel trapped gas and soothe irritated mucosa².
How to use:
- Steep 2 tsp dried flowers (or 2 tea bags) in 250 mL boiling water for 5–10 minutes. Drink up to 3–4 times daily¹².
Safety note: Avoid if allergic to ragweed or daisies¹.
4. Fennel (Foeniculum vulgare)
Use: Reduces gas, cramping, nausea, and supports gentle motility.
Evidence Level: ✅ Strong Support
Fennel seeds contain anethole, which provides antispasmodic, anti-inflammatory, and digestive effects. It’s specifically recommended for intestinal bloating and cramps¹.
How to use:
- Crush 1 tsp seeds; steep in 1 cup boiling water for 10–15 minutes. Drink 2–3 times daily after meals¹.
Safety note: Not for pregnant or breastfeeding women¹.
5. Aloe Vera (Inner Gel Only)
Use: Soothes and coats irritated intestinal lining.
Evidence Level: ⚠️ Traditional Use with Safety Caveats
The inner gel of aloe vera contains polysaccharides that soothe irritated gastrointestinal tissues². However, the latex (yellow sap near the rind) is a strong laxative that can worsen diarrhea and cause electrolyte imbalance¹².
How to use:
- Use only pure inner fillet juice—¼ to ½ cup once or twice daily².
Safety warning: Never use aloe latex. Avoid aloe entirely during active IBD flares or if you have kidney disease².
6. DGL Licorice (Deglycyrrhizinated Glycyrrhiza glabra)
Use: Protects and repairs mucosal lining (primarily upper GI).
Evidence Level: ✅ Strong Support
DGL (deglycyrrhizinated licorice) stimulates mucus production to protect the digestive tract. Unlike regular licorice, DGL does not raise blood pressure².
How to use:
- Chewable tablets: 760–1,520 mg before meals².
Safety note: Only use DGL form—regular licorice can cause hypertension and low potassium².
Herbs to Avoid in Intestinal Inflammation
- Aloe latex: Strong laxative—can worsen diarrhea and cause dehydration².
- Senna or cascara: Stimulant laxatives—unsafe during infection or IBD flares.
- Garlic (raw, high-dose): While used in garlic tea for short-term infections¹, it can irritate the gut lining during chronic inflammation.
- Regular (non-DGL) licorice: Raises blood pressure and lowers potassium².
Safety reminder: Always check labels for “DGL” or “inner fillet only.” When in doubt, consult a pharmacist or provider.
When Herbs Aren’t Enough: The Medical Reality
Herbs may support comfort, but they cannot replace medical care for chronic conditions like Crohn’s or ulcerative colitis. The Mayo Clinic emphasizes that IBD requires ongoing medical management to prevent complications².
Seek immediate care if you experience:
- Blood in stool
- Fever
- Dehydration
- Symptoms lasting more than 2 days¹
Think of herbs as part of a holistic plan—not a standalone solution.
