East-Indian screw tree is a
sub-deciduous shrub or small tree with grey coloured bark. Leaves simple,
serrate margin, scabrous above and pubescent beneath. Flowers solitary or in
sparse clusters, with red petals turning pale blue when old. Fruits greenish
brown, beaked, cylindrical, spirally twisted on ripening. The twisted shape
of the fruit is what lends most of it names like screw tree and maror
The roots and stem barks are considered to be
expectorant, demulcent, astringent and antiglactagogue. Bark is used in
diarrhoea, dysentery, scbies, biliousness and is useful in gripping of the
bowels. Root juice is used in antidiarrhoeal and antidysenteric formulations.
Fried pods are given to children to kill intestinal worms.
