I agree wholeheartedly with Hanna. Timeless Secrets of Health and Rejuvenation is THE best book I've ever read on health. There are a couple others up there on my list, but this book is definitely my fav!
A quick note for Texas...
Sorry, I know this isn't specifically Liver Flush related, but I wouldn't recommend doing candida cleanses. Candida will only thrive in a toxic environment and is actually doing your body a favor by digesting and eating toxins. Once the body is clean, candida levels will balance on their own. Killing it off before your body is ready will only fill your body full of dead candida which is just another toxin that needs to be dealt with - which in turn will breed more candida... - feeding a vicious cycle.
