 There are a lot of researchers that have shown that if your liver functions at only 40 percent, you still feel perfectly normal. It seems to be everything okay. You don't know. And there are no tests that will show you that your liver functions 100 percent. If your liver functions 100 percent, you need nothing. Your body is fine. If there's anything wrong, anything from menstrual cramps, PMS or from rashes or headaches or constipation or whatever, anything, the fault is the liver. And I strongly believe that there are very few, if any, people who are in perfect health never have a headache, never constipation, never have a diarrhea, never have a flu or a cold, never have anything at all ever, that they're really perfect health past the age of two. Yes.
