It might not be what you're looking for, but I've recently read Perfect Health the Taoist Way by Hua Sun. The book describes many natural positions of the body that help to stimulate the detox process, such as while sleeping or sitting. It also explains the circadian rhythm and how to eat (and not eat) at the right times, and to be asleep at the right times, so as to not interfere with the body's natural detox processes.
It's certainly not the only book on the subject, but it's easy to understand and apply. Here's the table of contents:
