Topical 1% nanomicellar curcumin oral gel as add-on therapy,
does it really help with Improvement of REU lesion severity in symptomatic oral lichen planus?
research showsGrade C with 54 points. In 31 patients all using 0.1% triamcinolone rinse, adding 1% nanocurcumin gel lowered the adjusted REU score by 5.93 points at week four, but this was a very small short trial.

Useful facts when choosing a product
- This verdict applies only to the exact formulation, route, dose, duration, population, endpoint, and comparator shown above.
- Conventional curcumin, turmeric powder, nano or micellar products, phospholipid phytosomes, piperine combinations, swallowed products, and topical oral products are not interchangeable.
- Caution. Four weeks of topical use cannot exclude long-term mucosal irritation, allergy, or absorption risks and does not support stopping standard therapy.

Bound to the 1% topical gel and REU lesion score; pain and swallowed formulations remain separate. The code identifies the intervention and claim; it never contains the evidence grade, score, or safety result.

What the research actually shows
Thirty-one participants were randomized to 1% nanocurcumin gel or placebo gel while both groups used triamcinolone rinse.
Why this is classified as C (54)
A direct placebo add-on contrast and large adjusted REU difference are offset by n=31, four weeks, and a surrogate lesion score, yielding C with 54 points.
Counterpoint. The estimate was large, but 14 versus 17 participants and multiple times and outcomes create substantial risk of exaggeration.
Rejudgment record. Independent Codex cross-check — One formulation, one route, one population, one claim, one principal endpoint and comparator
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
| Precision | C0 | The confidence interval leaves room for benefit |
The scoring table and the verdict agree (C).
