## Key Takeaways

- This page is generated only from sources stored in the Migaku evidence knowledge base.
- Current evidence mix: 1 randomized trial, 1 research article.
- Claims should be interpreted with the source type, study design, population, and publication date in mind.
- This article is educational and does not replace care from a qualified clinician.

## Evidence Map

| Source | Evidence type | Level | Date | Identifier |
| --- | --- | ---: | --- | --- |
| Perianal lidocaine application during unsedated colonoscopy: A double-blind randomized controlled trial | randomized trial | 2 | 2026-04-30 | 10.1371/journal.pone.0348062 |
| Medicinal Plants in Food Supplements for Gastrointestinal Disorders: Critical Assessment of Health Claims on Gastric Acid Regulation | research article | 4 | 2025-11-24 | 10.3390/nu17233674 |

## What The Sources Report

- Moreover, 17 patients in the lidocaine group and 18 patients in the saline group had previous abdominal surgery and no significant differences were found in previous operation history between the two groups. [Wang Jiankun (2026); evidence level 2]
- Our findings suggest that perianal lidocaine application may be associated with lower anal pain scores during unsedated colonoscopy, which can be attributed to the anesthetic impact of lidocaine on sensory nerves within the mucosal layer. [Wang Jiankun (2026); evidence level 2]
- Helicobacter pylori 1 2 3 4 2 Health conditions associated with stomach acid include gastroesophageal reflux disease (GERD), esophagitis, dyspepsia, chronic gastritis, gastric and duodenal ulcers, andinfection. [Teterovska Renāte (2025); evidence level 4]
- A potential alternative approach is the use of herbal medicinal products (HMPs) and food supplements (FSs) for the prevention and treatment of diseases and symptoms associated with increased stomach acid. [Teterovska Renāte (2025); evidence level 4]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

There is trial evidence in the current set, but population and intervention details still matter. For peppermint digestive comfort randomized trial, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
