I don't know the full answer but you need to be careful with the grapefruit juice. It helps because it stops the livers production of the enzyme needed to break down prazi and eliminate it.
A little extends the prazi half life but a lot will poison you with excess prazi.
Most people disagree but people have used alcohol for centuries to kill parasites. I use tequila because history shows that is what it was originally made for...killing parasites. Use the "white" form as it is the purest. Gold is aged in used whiskey barrels and therefore has contaminants.
Just an ounce to chase the parasite meds is enough. I don't know what it does but I trust old wisdom.
