Propolis linked to 65% lower odds of chemo mouth sores in a meta-analysis — but the studies weren't blinded and the total evidence is still thin.
This early meta-analysis suggests propolis might offer real relief for a painful side effect of chemotherapy, but the lack of blinding and small number of studies means the result is far from settled.
Oral mucositis — painful mouth sores — is a common side effect of chemotherapy. In this analysis of several small studies, people who took propolis had significantly lower odds of severe mucositis. However, the studies were not blinded (patients and researchers knew who got propolis), the dose of propolis used wasn't standardized, and the overall body of evidence is still very small.
Where this fits in the evidence
This is among the first studies we've indexed on Propolis for Improved Oral Mucositis — treat it as an early signal until more research accumulates.
