 So the PMF really helps for re-energizing. When you're doing any kind of chemo, it's really damaging, really draining of your life force or really draining of your energy because that radiation is also destroying the good cells in your body. So you need something to restore yourself. You need something to recover with. You need something to regenerate that life force inside of you so that your body will regain its own ability to heal itself much faster. And it's very difficult when your body is in a weak state. It doesn't digest. It doesn't absorb. It doesn't recover or regenerate that great at all. Even if you give it the best supplements, the best herbs, it's still gonna have a hard time digesting because it takes energy to digest your food. When you're in really weak state, your body is really weak state or sick state, it's harder for you to get healthy.
