Summary
This early-phase study tests whether a mouthwash made from copaiba, a natural oil from the Amazon, can safely help prevent and treat painful mouth sores caused by radiation therapy in 20 adults with head and neck cancer. Researchers will find the highest safe dose and measure pain levels. The goal is to offer an alternative when standard laser therapy cannot be used on tumor areas.
