Seaweed shield: spirulina derivative tested to stop radiation burns in throat

This study tests whether a product made from spirulina (a type of algae) can prevent severe throat pain caused by radiation therapy in people with esophageal cancer. About 70 patients will receive either the spirulina derivative or a placebo during their radiation treatments. The goal is to see if the supplement reduces the number of patients who develop moderate to severe esophagitis (inflammation of the food pipe).
