Associate Professor Severine Navarro is not talking about chickens or composting.
The immunologist is describing patients using hookworms — specifically Necator americanus — in an attempt to treat inflammatory bowel disease (IBD), coeliac disease, COPD and eczema.
‘Doses’ of juvenile hookworms retail online for between $90 and $300, including shipping, while websites like Helminthic Therapy Wiki provide advice on dosing and worm care.
