Ginger may guard against the progression of some autoimmune diseases

A new study on mice showed that ginger may counter certain autoimmune disorders such as lupus and antiphospholipid syndrome.

  • A new Michigan Medicine study on mice suggests that the primary bioactive compound of ginger root, 6-gingerol, could help counter the autoimmune disorders lupus and antiphospholipid syndrome.
  • The researchers found that the mice had lower levels of NETs (which play a role in the pathogenesis of lupus and antiphospholipid syndrome by stimulating autoantibody formation) after being giving 6-gingerol.
  • 6-gingerol won't be able to be the primary therapy for individuals with lupus or active antiphospholipid syndrome, but the research team is eager to see if the natural supplement offers help to those at high risk for developing the diseases.
