„The roots of burnet are known to be effective against acute diarrhoea. The herb also has antihaemorrhage properties and has been used to treat ulcerative colitis, metrorrhagia (uterine bleeding) and topically against haemorrhoids, various skin conditions (wounds, ulcers, burns and eczema) and mucosal inflammations (included in gargles and tooth pastes). The main traditional use (in Europe and China) is to stop bleeding, as is reflected in the generic name sanguis (blood) and sorbeo (I absorb)… The tannin and saponin contents are clearly in agreement with the observed astringent, antimicrobial, anti-inflammatory, haemostyptic and antidiarrhoeic effects.“

„The yields of crude eq-extracts, polysaccharide, flavones, tannins and saponins by extraction, isolation and partial purification form Sanguisorba Officinalis in this experiment… were 1.45 %,1.27 %,0.87 % and 0.88 %. The results of the enzyme kinetic assays showed that tannins and flavone had a better inhibition effect than Glucobay. And both of their inhibition was competitive; Ki of tannins and flavone were 0.030 9 mg/mL and 0.076 5 mg/mL; IC50 of them were 8.13×10-2mg/mL and 0.266 mg/mL. Flavone showed a higher thermal stability, but tannins hadn't the property. The experiment confirmed that Sanguisorba officinalis was a good source of α-glucosidase inhibitors and Sanguisorba officinaliss flavone and tannins may become promising candidates for blood sugar reducing functional factors.“
