There is definitely some strong evidence suggesting ties between the way gut parasites change the function of our immune system and autoimmune disorders. Autoimmune responses are responsible for a vast array of debilitating conditions ranging from allergic reactions to IBS to Crohn’s disease, even the cytokine storms that are often the cause of death in viral infections. Cultures who have parasites as part of their environment typically are aware of plant remedies that control the parasite loads as well, as uncontrolled parasite load can result in health consequences including mortality. Like so many other things, balance and management are key concepts. Several people affected with debilitating and life threatening allergies have documented their recovery through intentional infection with hookworm parasites. An interesting rabbit warren for sure.
