Sep 27, 2023 by News Staff

In a new clinical trial, scientists from the University of Michigan, Ann Arbor and the University of Colorado School of Medicine found that oral administration of ginger modulates neutrophils (type of white blood cell) and neutrophil extracellular trap (NET) formation, also known as NETosis, in autoimmune mouse models and healthy humans. This is important because NETs are microscopic spider web-like structures that propel inflammation and clotting,...
