(2005) demonstrated that the application of bloodletting cupping (BLC) as a complementary therapeutic intervention in the management of rheumatoid arthritis (RA).Specifically, the therapeutic modality showed statistically significant reductions in serum C-reactive protein (CRP) concentrations and demonstrated observable improvement in erythrocyte sedimentation rate (ESR) measurements compared to control groups.
