Sorry 'bout that, Keah. Calling them "your" worms. Anyway, there's been some success treating Crohn's w/sterile worm eggs that was developed right here in the US that Keah had some success with.
Well, now Necator americanus, a hookworm, has been found to have some success in treating hay fever and asthma sufferers. They stimulate the body to produce white blood cells called regulatory T-cells, that dampen down the immune response. There are plans for studies on Crohn's disease and multiple sclerosis.
"If you superimpose a map of where hookworms are found, you will see that asthma and hookworms seem to be mutually exclusive," he said. "Similarly, Crohn's disease seems to be a disease of the developed world."
It was decided the correct dosage was ten - any more resulted in discomfort; any fewer and the immune-suppressing effects were not strong enough. The worms cannot reproduce inside the body and are eradicated with tablets.
