I'll get back to you on Autolysis, when I have more time, but in the meantime....
Autolysis (a-tol-i-sis) is derived from the Greek and means, literally, "self-loosing". It is used in physiology to designate the process of digestion or disintegration of tissue by ferments (enzymes) generated in the cells themselves. It is a process of self-digestion or intra-cellular digestion.
Autolysis is a rigidly controlled process.
Sylvester Graham wrote: "It is a general law of the vital economy, that when, by any means, the general function of decomposition exceeds that of composition or nutrition, the decomposing absorbents always first lay hold of and remove those substances which are of least use to the economy; and hence, all morbid accumulations, such as wens, tumors, abscesses, etc., are rapidly diminished and often wholly removed under severe and protracted abstinence or fasting."--Science of Life, pp. 194-195.
Fasting animals, whether hibernating, æstivating, fasting during the mating season, fasting during illness, or fasting because of a lack of something to eat, do not have and do not need enemas. Some of these animals fast for much longer periods than is possible for any man and do not die of nor suffer from the much-feared poisoning by absorption from the colon (autointoxication).
Many fasters report that they can "feel better" after an enema/colonic but in reality is short term effect due to stimulation, as with any other form of stimulation.
