I was searching online and found nothing about what I mentioned.

But it says it's good for digestion, good for feeling satiated in meals and about uric acid I read it produces it or contains it.

The uric acid I read it can be bad and I read it can be good. Too much can lead to arthritis. And in due quantities it is a powerful antioxidant.

I don't know really.

Mate is being the companion of gauchos for centuries and they ate mostly red meat. Cannot be a casual thing you know. Because gauchos are mostly from a region in which yerba mate doesn't grow so it has to be imported. So the correlation might be purposeful.
