Yes, you can. The drugs and supplements mentioned in the question do not have clinically significant interactions with each other that would exclude their combined use.

Black cumin oil may theoretically increase the anticoagulant effect of nattokinase, which may increase the risk of bleeding. Isoptin SR-120 (verapamil), on the other hand, can interact with hypertension medications, increasing their effects. Therefore, the simultaneous use of these three substances should be done under the supervision of a doctor and requires regular monitoring of blood pressure to avoid too low pressure.

In case of any doubt, it is recommended to refrain from using these three substances simultaneously without medical supervision to avoid potential side effects. If you are not able to make a face-to-face visit, I attach a link to the online teleconsultation:
