the effects of dewormers and so forth seem to be harmless compared to mms. i haven't really had any adverse symtoms through the use of dewormers and i have seen plenty of nasties thus far.
they kill parasites and literally nothing else. mms is super wide spectrum in the sense that it kills all pathogens on a cellular level. larger parasite organisms in the colon or liver die from the dewormer, coming out in the stool either straight away or after a liver flush.
