If you’ve taken an over-the-counter decongestant in the past 20 years, you’ve probably taken something with phenylephrine as the main active ingredient. And you may have noticed that, despite taking it, you’re still congested.

In the above video, Vox senior producer Phil Edwards chronicles the history of the FDA’s regulation of over-the-counter medicines. That process is the reason that, despite decades of evidence that phenylephrine doesn’t work (especially in typical OTC doses), it has remained a readily available option for clogged-up consumers.
