Is (and why is) physical health important, as well as mind?

As we all know, the Buddha taught that everything is about mind -- including for example that Dukkha exists because of mind, because desire came into mind first no matter if it would affect us physically, because the main stream is the mind. Even when the Buddha wasn't able to walk, yet he was enlightened. So I would also ask if physical health would ever affect mind or mental health? What about breaking precepts if it's matter of health -- for example if I'm suffering from headache then I can have aromatic therapy, or medicine including a little alcohol, or listening to music like that. Why is the body important when one is enlightened or mindful? Can't we ignore what is happening with our body, and concentrate still on being calm, and focus on mind?
