I have some bad news for you about Tylenol/Paracetamol.... The science is "We did many double blind studies on a large population and observed these effects to a degree statistically significant compared to placebo" We can reproduce the effects reliably, and the side effects are similarly predictable. We've also researched the pharmacokinetics to see what it's doing, but we don't necessarily understand how those changes cause it's effects. Just because we don't know exactly how it works, doesn't mean we didn't observe what the effects are. When the good effects out way the bad effects then it's a possible treatment. I'm not saying all studies are of quality, that there aren't unknown effects we haven't observed yet, that there aren't problems etc. What I'm saying is we have at least attempted to measure the effects and determine them to a statistically significant degree. tl;dr - If we've measured effects to a statistically significant degree - that is not a cargo cult.
