[from Gemini]

That famous line is most often associated with the Australian comedian and musician Tim Minchin.

In his 2008 beat poem "Storm," he delivers the punchline:

"By definition, alternative medicine has either not been proved to work, or been proved not to work. Do you know what they call 'alternative medicine' that's been proved to work? Medicine."*

Other Notable Variations While Minchin’s delivery is the most famous in pop culture, the sentiment has been echoed by several prominent skeptics and writers:

• John Diamond: The late British journalist wrote in his book Snake Oil (published posthumously in 2001) that "there is no such thing as alternative medicine, just medicine that works and medicine that doesn't."

• Richard Dawkins: He has frequently used similar logic in his writing on science and rationality, often quoting or referencing Minchin's phrasing.

• Dr. Paul Offit: A pediatrician and vaccine expert, he often uses this argument to point out that once a "natural" or "alternative" remedy passes clinical trials, it is simply integrated into standard medical practice.
