Proofs of the efficacy of De Velno's vegetable pills, as the most safe and certain cure for the scurvy, scorbutic eruptions, scrophula or king's evil, leprosy, and other disorders, ... : with some pertinent remarks on their utility as spring physic; demonstrating the propriety of taking alterative medicines.
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 uses the 'us vs. them' tactic by positioning its 'vegetable' pills against the known 'Danger of Antimonials or Mercurials'. It proves the claim with highly detailed, verifiable stories of patients who avoided 'hazardous salivation' (mercury side effects).
Steal this when
Your product is a safer alternative to the dangerous or painful industry standard, and you have dramatic stories of people you've saved from the standard treatment.
