Natural remedy st. John's wort put to the test against standard mouth ulcer treatments
NCT ID NCT06839313
First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time
Summary
This study compares three treatments for recurrent aphthous stomatitis (canker sores): St. John's wort oil, a topical corticosteroid, and hyaluronic acid gel. Researchers measure how well each reduces pain, shrinks ulcer size, and speeds healing in adults with a history of these painful mouth ulcers. The goal is to find which option works best for symptom relief.
