Silver bullet

See the real Africa
The metaphor of the silver bullet applies to any straightforward solution perceived to have extreme effectiveness. The phrase typically appears with an expectation that some new technology or practice will easily cure a major prevailing problem. Some have seen such apparently miraculous drugs as salvarsan and penicillin as "silver bullets".

Experts often use the term more cynically to dampen unreasonable expectations. Doctorss, for example, will often readily characterise the latest fad diet as "no silver bullet".

The term originates from the mythology of werewolves: allegedly, only a silver bullet could kill a werewolf. As a more modern popular culture example, the Lone Ranger also used silver bullets.
