I don’t know where those people learned it, but that’s what Jesus did to remove a tapeworm in The Essene Gospel Of Peace Book One (fromthealphatotheomegadotcom.files.wordpress.com).
And Jesus milked an ewe which was feeding among the grass. And he put the milk upon the sand made hot by the sun, saying: "Lo, the power of the angel of water has entered this milk. And now the power of the angel of sunshine will enter it also."
And the milk became hot by the strength of the sun.
"And now the angels of water and of sun will join with the angel of air."
And lo, the vapor of the hot milk began to rise slowly into the air.
"Come and breathe in by your mouth the strength of the angels of water, of sunshine, and of air, that it may come into your body and cast out the Satan from you."
And the sick man whom Satan tormented did breathe within himself, deeply, the rising whitish vapor.
"Straightway will Satan leave your body, since for three days he starves and finds no food within you. He will come out of you to satisfy his hunger by the hot steaming milk, for this food finds favor in his sight. He will smell its smell, and will not be able to resist the hunger which has tormented him three days already. But the Son of Man will destroy his body, that he may torment none else again."
Then the sick man's body was seized with an ague, and he retched as though he would vomit, but he could not. And he gasped for air, for his breath was spent. And he fainted on the lap of Jesus.
"Now does Satan leave his body. See him." And Jesus pointed to the sick man's opened mouth.
And then they all saw with astonishment and terror that Satan was coming out from his mouth in the shape of an abominable worm, straight towards the steaming milk. Then Jesus took two sharp stones in his hands and crushed the head of Satan, and drew out from the sick man all the body of the monster which was almost as long as the man. When the abominable worm came out of the sick man's throat, he recovered at once his breath, and then all his pains ceased. And the others looked with terror at the abominable body of Satan.
"See, what an abominable beast you carried and nourished in your body for long years. I have cast it out of you and killed it that it may never again torment you. Give thanks to God that his angels have made you free, and sin no more, lest Satan return to you again. Let your body be henceforth a temple dedicated to your God."
whoa, thanks for opening up that avenue of exploration to me
That was quoted in Parasite Pill 2.0 (archive.org). Almost everything I know about parasites is from that document or things it told me to search for.
Wow - had no clue. Interesting.
