Did the Romans consume silphium to extinction?

Well, here I am, I ended up following a comment made by Hamilton Morris on a New Health Club video about how the Romans consumed silphium to extinction and why this reflects on the unsustainable harvesting of Tabernanthe Iboga (among other psychoactive organisms).

Anyway, apparently the Romans didn’t really do that.

That’s just a random fact though, I’m sure over-harvesting of Iboga and other plants/animals is a real problem and its conservation and sustainable harvesting methods are critical to its preservation.
