Definition of Fomentation
Fomentation: A quaint old term for the application of hot packs or the substance so applied. From the Latin "fovimentum" which meant, no surprise, to "a warm application."
To "foment" means, literally, to warm or heat up. It is, figuratively, to incite. For example, to forment fear.Source: MedTerms™ Medical Dictionary
