I do not know if the spit test is accurate or not. However in the link I gave you there is info on how to see if candida is in your colon. If it is there it needs to be cleaned out & you can assume it is in other parts of the intestine too, I would assume.
I found Epsom Salts to be unnecessary & also exhausting. Wait at least a month after parasite cleansing to do a liver flush. All that is in the info I gave you too. It is a lot of stuff to read, I know. Also stuff is in there about adrenals & thyroid, like don't count on those blood tests.
