Pancreatic enzymes digest food after it had been prepared by chewing and mixing with mouth enzymes and agitated in the stomach with strong acid. Most parasites will not be digested by enzymes unless they are dead and starting to fall apart as most have a very tough and resistant coating the enzymes can't penetrate.
A mixture of enzymes with cellulose is used in newer treatments for intestinal yeasts such as Candida. I wears away the biofilm where they live exposing the yeasts to treatment with herbs or Antibiotics .
Your husband may carry parasites with no obvious symptoms and if you are successful is ridding yourself of your parasites it is possible to be reinfected from him and anybody else living in the home, including pets.
