Beneficial Effects of Kangkong Against Liver Disease

An ethanol extract of kangkong has been administered to rats subjected to liver damage by thioacetamide. Results had shown that the rats when compared to a control group showed resistance against liver lesions, cell necrosis and inflammation. The study further suggests that the protective effect of kangkong extract in chemical-induced liver damage might be contributed to its modulation on detoxification enzymes and its antioxidant and free radical scavenger effects. Moreover, it confirms a scientific basis for the traditional use of kangkong for the treatment of liver disorders.
