What this trial studies

This Phase 1, single-arm, self-controlled pilot tests a topical 20% Cassia alata extract cream applied twice daily to affected skin while other areas are left untreated as internal controls. Clinical and microbiological resolution will be compared between treated and untreated sites with visits at baseline, 1 week, 4 weeks, 8 weeks, and 12 weeks. Safety, tolerability, and ease of use will be recorded at each visit to document any local reactions or adverse events. Results will be analyzed descriptively and with simple statistical comparisons to inform whether larger controlled trials are warranted.

Who should consider this trial

Good fit: Adults 18–89 with clinically and microscopy- or Wood's lamp–confirmed tinea versicolor who have not used antifungal treatment within the prior 4 weeks and have no known allergy to Cassia alata or preservatives.

Not a fit: Pregnant people, those with lesions that do not meet diagnostic criteria, individuals who used antifungal treatment within the past 4 weeks, or anyone with known hypersensitivity to Cassia alata or its preservatives are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the cream could provide an affordable topical option to clear tinea versicolor with a tolerable safety profile.

How similar studies have performed: Cassia alata has traditional use and limited laboratory reports showing antifungal activity against Malassezia, but clinical trial evidence is scarce, making this a relatively novel clinical test.
