The corolla tubes are orange-coloured tubes found inside the flower and when severed from the hand give a beautiful fleeting orange or golden dye.  Corolla tube contains a colouring matter, nyctanthin, which is identical with crocetin from saffron.

It is also used for colouring other kind of fabrics and for imparting colour to liquor. The whole flowers yield a fine buff or orange brown dye. It is much used in combination with other dyes.  The inner bark afford a red dye when beaten with a little lime. Bark yields a  tanning material, expectorant.
