Ivermectin, fenben, menben, alben, and prazinquintal all treat different types of parasites.
I like a base protocol that's fairly gentle, using natural products, and then perhaps once a year use drugs to get a more comprehensive clean.
At least once in your adult life should you employ all of the antiparasitics over the course of 3-4 full moons.
The West has a big parasite problem ever since standard care effectively abandoned the field.
