Remarks on Major's influenza drinks / [J. Major].
The pattern
This still sits in the public-domain pool. No pattern name yet.
Why it works
The pamphlet opened with clinical descriptions of seasonal respiratory misery before introducing the proprietary drink as a specific corrective. By detailing symptoms the reader was currently suffering, it created immediate physiological recognition before pitching relief.
Steal this when
Steal this when selling symptomatic relief and you need to validate the prospect's immediate discomfort before naming your solution.
