Grade C: Limited Evidence
Evaluation of methodological rigor, population reach, and evidence alignment.
- Design Match
- Systematic review
- Risk of Bias
- Low
- Consistency
- Consistent
Strongest recorded design is a systematic review, drawn from 5 recorded studies, 3 in people. No disagreement is recorded across them.
How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials

Background | Randomized controlled trial Randomly assigns participants to interventions or controls, reducing many sources of bias when the trial is conducted well. | — | — | — | — | — | A randomized ICU study (80 participants) reported fewer pressure ulcers with topical henna applied to the sacral area. This is a topical, setting-specific signal and should not be generalized to oral henna or broad wound-healing claims. | PubMed → |
Background | Randomized controlled trial Randomly assigns participants to interventions or controls, reducing many sources of bias when the trial is conducted well. | — | — | — | — | — | A small randomized trial in oral lichen planus found no significant advantage for Lawsonia inermis as an adjunct over the comparator regimen. This is useful null evidence that tempers generalized anti-inflammatory claims. | PubMed → |
