Dr. Brian Staiger explains PharmD, Clinical Pharmacist

The piece of this combo product I want to focus on is the aspirin. Aspirin already works by making your platelets less sticky, which is how it thins the blood. Cumin, at least in lab studies, seems to do a little of the same thing. So putting them together could, in theory, nudge your bleeding risk up a bit (think easier bruising, nosebleeds, or a cut that takes longer to stop).

Now, here's the honest part: this concern comes from test-tube research, not from people, so it's pretty theoretical. Sprinkling cumin on your food is very unlikely to cause any trouble. Concentrated cumin supplements or oil are where I'd be more cautious. If you take those regularly, just run it by your pharmacist or doctor first.
