Summary
This study planned to test a mouthwash made from copaíba oil, a natural resin, to prevent and treat painful mouth sores (oral mucositis) in people with oral cancer undergoing radiation. The trial was set to include 40 patients, half using the copaíba mouthwash and half a placebo, four times a day. However, the study was withdrawn before any participants were enrolled, so no results are available.

What this could lead to
If it had worked, this could have pointed toward a natural mouthwash to ease painful mouth sores during cancer treatment.
What could go wrong
The trial was withdrawn before enrolling any participants, so no results are available. Even if conducted, it was a small early-phase study with only 40 patients, so success was uncertain.
