Can body heal itself naturally?

Hi. My friend claims body can heal itself naturally. I say it can`t. You need meds and herbs and therapies. You need doctors when you have wounds, otherwise you will end up infected or something like that. I think body can treat itself when injuries are minor. Can body heal itself naturally?

Of course it can. Your body has its` own healing system. It is called immune system. It protects you from anything in the world that threatens your body and life. You must take care of your immune system because it is the main thing in staying healthy. Did you know we all get cancer every day, but immune system eliminates them and you never found out? It is so great. Meds, herbs, and stuff like that are here to stimulate the body`s natural abilities to heal naturally. Homeopathy, for example, is a very safe alternative method to help your body in healing process.
