I had heard a similar method for removing intestinal worms. you fast for 2 days.. and take some laxatives to completely empty your bowels. then you fill a small tub with milk and LOTS of sugar.. then sit in this tub naked for a few hours.. the worms will start coming out of your anus to feed themselves..
the point of fasting is to starve the worms.. you take laxatives to empty your bowels so that the worms can later try to reach the milk/sugar solution without any barriers..
I never tried this method but I guess it must be worth trying.. and it maybe better than trying to pull worms from the mouth..
