Cleansing the liver should help, which is why you're probably seeing the references to hep. How do you know your levels are high and that your body isn't doing its job of dealing with this inevitable byproduct of protein consumption with urea? Have you had a test done? Just once? As always, I advise people who don't know what they're doing to see someone who does, so if this is a continuing problem that has been diagnosed I'd see a naturopath or holistic nutritionist and get some expert help. After all, the only way you'll know if it's working is getting tested repeatedly. But again, a healthy liver should be taking care of this.
By the way, do you consume excess protein? Such as what bodybuilders do? This is one of the possible adverse consequences of protein loading.
Third, do you know if your intestinal flora is healthy?
Thats interesting about the liver detox. I actually heard most of the holistic techniques were bad for the native bacteria. Does anyone know more about this?
The native bacteria isn't really in the liver -- it's mostly in the intestinal tract, though our entire body is really a colony of organisms. And I've not heard that cleaning the colon disrupts beneficial bacteria, though it's certainly possible to do that in theory, I suppose, if you did it all the time. Periodic cleansing, either by fasting or cleansing, would seem to present a more hospitable environment for beneficial organisms by keeping it healthy, but who knows?
