Definition of the word magic bullet

The term "magic bullet" was coined by scientist and Nobel laureate Paul Ehrlich in 1906. Ehrlich introduced the concept of chemotherapy, which is the use of drugs to treat diseases. He explained that just as a bullet, when aimed correctly, hits a target with precision, certain drugs delivered to a specific part of the body could selectively attack diseased cells or tissues while leaving healthy ones unharmed. This idea became known as the "magic bullet," as it promised a groundbreaking approach to treating diseases with the accuracy and potency of a bullet. The term has since been used in various contexts to describe therapies that target specific biological processes with incredible precision.
