Sorghum bicolor extract has been shown to increase the haematocrit and haemoglobin level and reduce the white cell count in trypanosome brucei brucei induced anaemia in experimental rabbits.

This might be as a result of direct effect on these organs or a sign of cardiotoxicity. However there is a wide therapeutic range.
