An infusion of the leaves of Banaganjei is used in the treatment of fever, cough and bronchitis, and as a gargle for toothache. A hot infusion acts as a diuretic and a cold decoction of the plant is used to provide relief from gravel and kidney complaints. An infusion of the leaves, roots and flowering tops is considered useful for treating dysentery and diarrhea. A decoction of the roots and leaves of this medicinal plant is used to relieve fevers. All parts of the plant are used as an emetic. The aqueous extract obtained from the crushed aerial portions of this plant is taken orally in the treatment of spermatorrhoea among the tribal inhabitants of central Orissa. In eastern Bihar, the leaf juice is taken with yoghurt for treating jaundice; this region's tribal women also use the juice of the plant to test for pregnancy, and when mixed with urine, a colour change is considered a positive indicator. The fresh stems and leaves contain an antidiabetic compound (amellin) which gives relief from the symptoms of glycosuria, reduces hypergly-caemia, increases red blood cell count, and is useful for relieving several complications linked with diabetes mellitus. Amellin reportedly reduces both urine and blood sugar level more gradually than that of insulin.
