Turmeric mouthwash cut oral mucositis severity and pain in cancer patients on radiotherapy — but the evidence comes from just 159 people across a handful of small trials.
This is an early, promising signal for a specific clinical use of turmeric, but the small sample size and narrow patient population mean the finding may not apply to healthy people or other forms of the supplement.
A systematic review of 159 cancer patients found that turmeric and curcumin formulations, especially curcumin mouthwash, significantly reduced the severity of oral mucositis (painful mouth sores from radiotherapy) and lowered pain scores. The analysis also estimated a 37% reduction in the chance of developing mucositis, but these results come from a small number of studies and only apply to people undergoing cancer treatment — not to general use.
Where this fits in the evidence
This is among the first studies we've indexed on Turmeric for Reduced Oral Mucositis Severity — treat it as an early signal until more research accumulates.
