The cestocidal activity of Acacia auriculiformis was valuated using ra
ts each harbouring a single adult worm of Hymenolepis diminuta. The et
hanol extract (300 mg/kg/day) and the saponins (200 mg/kg/day) obtaine
d from the funicles of A. auriculiformis, were administered orally to
two groups each of 10 rats, respectively, on day 20 after oral inocula
tion with a single cysticercoid of H. diminuta. Adult worms were expel
led within 5 days from rats treated with the ethanol extract and withi
n 3 days from those treated with saponins. No appreciable side effects
were observed in the treated rats.
