Immuno-supressing drugs used to treat those conditions have nasty side effects, like increased opportunistic infections and cancer rates. Beating lupus and the like requires a new approach, and some doctors are getting unexpected help from parasites like the pig whipworm. They call it Helminthic therapy, and it involves administering parasite eggs to patients so that their bodies can go through the normal series of reactions. The worm larvae hatch inside their hosts as normal, or sometimes they're served in delicious worm egg purees! Yes, delicious pig-whipworm-egg smoothies, just like the future promised.
Clinical trials have been underway for over a decade, but there's a bureaucratic catch in America. For some crazy reason, the FDA isn't keen on selling parasites over the counter or signing off on the relevant studies. But Europe's attitude toward biological specimens harvested from the shit of strangers are a little looser, and the Germans are close to approving an over-the-counter health supplement that will some day be sold right next to Quest bars. Surely it will only be a matter of time until Gwyneth Paltrow is hawking Goop-brand Gutworms.
