I can only say, that taking Aspirin (I'm from the UK), helps to thin the blood and it is recommended by doctors here, to take one daily, just one.
However, the arteries are very important so I advise you to seek the advice of a qualified Physician and NOT try for home remedies. As the Aorta is the main artery to the heart, you should see someone without delay. You can ask him/her then, about taking Aspirin. How do you know that your Arteries are clogged---and why have you needed to come on a site like this for help with something so important, when the person who told you that you had clogged arteries, should have helped you further?
Anyway, I hope I have managed to help you.
In any case, to further answer your question; if your arteries are clogged, I believe it to be a surgical operation that you will need--but, having said this, these are ONLY my thoughts, which is the reason why you need specialist advice.
