Natural enzymes can
There are several natural enzymes that break a part clots, such as nattokinase, lumbrokinase, serratiapeptidase, bromelain, papain and other proteolytic enzymes.
These enzymes can be taken separate from food and help thin the blood and keep clots from forming as well. As such they will not work best in the acute setting. Anyone taking a blood thinning med needs to discuss this with their doctor.
