Clinical test: root Dekokta reeds with a dose of 250-300 g, two times morning and evening can be cured 27 cases of 30 patients with acute nefritis. In chronic nephritis, herbaceous weeds can reduce edema and lower blood pressure. Dekokta herbs 250 g in the singular or combined with Nelumbo nucifera rhizome and leaf and leaf Agrimonia pilosa can treat epistaxis, haemoptysis, hematuri, menorrhagia, and upper gastrointestinal bleeding.

A possible derivative of flavonoids, including flavone group, the substituted flavonol 3-0H, flavanone or the isoflavones contained in the soluble fraction in ethyl acetate extract of the roots of the reeds. In the fraction of water-soluble extract of the roots of the reeds of the flavonoids found in groups without free OH groups, flavones, flavonols substituted at the 3-0H, flavanone, or isoflavones.
