what you describe for poisons (like arsenic) is hormesis, but not "desensibilisation" nor "homeopathy".
the basic of hormesis is to activate the "heat shock proteins" so the body can fight against some class of genotoxic aggression... work for some poisons, radiation, sun, heat... Those HSP production can also cause some memory, through epigenetic modification, or simply though growth and selection. he basic of desensibilisation is to activate the immune system at low intensity, for long time, with increasing dose, without the usual co-factors of infection (that are simulated by "adjuvant" in immunization), so that the immune system activate the tolerance mode used for "self" and for "usual benign antigen". That tolerance mode in fact activate killing/suicide/suppression of the lymphocyte that react to that benign antigene. the basic of immunization is to stimulate strongly the adaptative immune system, in a way that really look like a real aggression (with adjuvant simulating the produce that the native immune system detect), so that the body activate the "war-mode", and a population of sensible T4 lymphocyte are created and kept for later fast detection. the basic of homeopathy is to use very very very low dose, and it works differently from those 3 techniques. It normally have no effect on HSP or immune system... 2012/9/25 ChemE Stewart <[email protected]> > Same effect with moist poisons.
