) decoction is a folk remedy for asthma, bugbites, burns, catarrh, diarrhea, fever, nausea, stomach distress and tumours. Also this plant has haematinic effects and has been used in the treatment of anaemia and other related ailments. Sweet potato leaves were used to feed rabbits.

While the differential white cell count remained the same. Increase in haematological parameters after feeding with the sweet potato leave extract may be a direct effect on haemopoietic tissues.
