Vinegar
Folk medicine

Since antiquity, folk medicine treatments have used vinegar, but no conclusive evidence from clinical research supports health claims of benefits for diabetes, weight loss, cancer, or use as a probiotic. A systematic review and meta-analysis later suggested it could help type 2 diabetics reduce insulin and glucose after meals.

Applying vinegar to common jellyfish stings deactivates the nematocysts, although not as effectively as hot water. This also applies to the Portuguese man o' war, which, although generally considered to be a jellyfish, is not (it is a siphonophore).

Some treatments with vinegar pose risks to health. Esophageal injury by apple cider vinegar has been reported, and because vinegar products sold for medicinal purposes are neither regulated nor standardized, such products may vary widely in content and acidity.
