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.

What this could lead to
If successful, this could identify a more effective or natural option for easing pain and speeding healing of recurrent mouth ulcers.
What could go wrong
