Ayer's Ague Cure is warranted to cure all malarial disorders / prepared by Dr. J.C. Ayer & Co.
The pattern
This still is filed under Borrowed medical authority.
Define
The claim wears a lab coat: a diagram, a percentage, a clinical tone that is not necessarily a clinician.
Mechanism
Authority costume. Science-looking form transfers trust. Use it only when the substance matches, or we are documenting a historical mechanism. We do not recommend the abuse.
Verdict
We have real evidence and the buyer needs it in a form they already trust: a chart, a protocol, a named standard.
Why it works
It differentiates itself from competitors by pointing out their dangerous ingredients (quinine, arsenic), positioning itself as the safe, natural, vegetable alternative.
Steal this when
When your product is entering a market filled with harmful or low-quality alternatives, highlight their flaws to elevate your safe option.
