Remember Curcumin? https://blogs.sciencemag.org/pipeline/archives/2017/01/12/curcumin-will-waste-your-time https://blogs.sciencemag.org/pipeline/archives/2017/01/12/cu... > Taking the properties and activities all together, though, these efforts would seem to be largely – and almost certainly completely – wastes of time and money.
