Swine have historically been considered unclean and full of parasites, even certain religions forbid the consumption.
This medical book was written in 1889, they were just starting to discover micro-parasites swimming around cancer tumors. That disappeared real quick from the global consciousness.
Would it be too far fetched to believe that they, controllers of medicine/world, don’t want you to consider deworming because there’s a ton of money to be made from sickness? How much have they raised for cancer research to still not have a cure?
