Black seed, fish, and coconut oil

I have just very recently begun to learn about black seed oil and all its health benefits and I am amazed to learn all I am about it. I have been using fish oil and coconut oil along with olive oil for the last few years. If I incorporate the black seed oil into my diet, should I eliminate any of the other oils? I just ordered the black seed oil and seeds from Amazing Herbs, waiting on my order. I want to use it for the health benefits to stay healthy. I do take meds for hypertension and am also wondering if there is any concern there. I am very new to all this,the oil, the forum etc. so I hope someone will actually read this and of course reply. Thank you to whoever will read and reply.
