Worth noting that this is a review of other studies. They don’t find that these things don’t work, they find that the other studies are so low quality as to be not highly meaningful evidence one way or the other. > Although some studies showed statistically significant improvements in hangover symptoms, all evidence was of very low quality, usually because of methodological limitations or imprecise measurements. I would be very surprised if naproxen (a common NSAID, and one of the cures in question here) doesn’t help hangovers somewhat, but the authors are correct that no high-quality research looks into this. Edit: this is sort of one of the unfortunate things about academic research culture. If I’m a good researcher, I could spend time looking into whether NSAIDs help with hangovers… but there’s already a bunch of lower quality research that does the same thing, and it’s very probable that my results would align with everybody’s priors (no surprise that a painkiller and anti-inflammatory would help with hangovers, which are in large part pain and inflammation) - so getting a ton of citations off it would be unlikely. So there’s really no incentive to spend a lot of time doing high quality research on something like this.
