Plasminogen (PAI-1) inhibitor.
You have to inhibit the inhibitor to semi-restore the system. Oleuropein (from olive leaf) does this. It's part of the post-vaxx protocol.

Also seems, via the same PAI-1 inhibition to exhibit potent anti-cancer effects.
Since the spike proteins cause PAI-1 to massively overexpress, a potential cause of the massive clotting in the vaxxed, could also be the tie in to increased cancer rates.
