510 Medicines - and Most Were Here Before Europe

"Indigenous medicine was just superstition." You've heard it your whole life. So scientists did the boring, brutal thing that ends arguments: they counted. In a survey of the plant medicines still in active use in northern Peru, researchers cataloged 510 medicinal species - a working pharmacy hiding in plain sight.

510 species - and 83% are native

Here's the number that actually stings. Of those 510 species, 422 - about 83% - are native to Peru. Not carried over on Spanish ships. Not borrowed from Europe. Already growing here when Europe showed up. The medicine cabinet was on this continent all along.

And this isn't a museum piece. Hundreds of these native plants are still in daily use today - for fevers, wounds, infections and pain. A living, working pharmacopeia, not a relic under glass.

Now the honest part

This is where we tell it straight, because the caveat is the interesting part. A plant being native to Peru does not prove its medicinal use is pre-Columbian. "Still used" does not mean "unchanged since the Inca."

The evidence is right there in the survey: about 66.5% of the plant names people use are Spanish-origin. This is a syncretic tradition - Indigenous and Spanish knowledge blended together over roughly 500 years of contact. The healer's table today can hold dried herbs beside a wooden cross, and that blend is the accurate reality, not a contradiction.

But the plants underneath were American

Strip away the 500 years of blending, and look at what the whole system is built on: the plants. Overwhelmingly American. The knowledge got layered and swapped and Christianized - but the pharmacy itself, the actual living green material, was native soil, native species, here first.

Keep the scope honest - this is northern Peru specifically, not "all of Peru" or "the Andes" or "Latin America." One rigorously counted region is enough. Not superstition. A science of plants. Mexican by name. American by history.
