This document summarizes a study that investigated the anti-anemic effects of the methanolic extract of aerial parts of Polygonum glabrum in phenylhydrazine-induced anemic rats. Rats were divided into several groups, including a control, standard, and two test groups administered 200 or 400 mg/kg of the Polygonum glabrum extract. Hematological parameters were measured and showed that the 400 mg/kg dose improved hemoglobin levels similarly to the standard, indicating an anti-anemic effect. The study concludes that compounds like phenolics and flavonoids in Polygonum glabrum have anti-anemic properties by protecting against hemolysis caused by phenylhy
