Abstract
Processes for selectively comminuting impure psyllium seed husk. These processes comprise milling impure psyllium seed husk in a mill which causes the husk to be fragmented by collision under conditions whereby the mean particle size of the husk material is reduced relatively more than the mean particle size of the non-husk material. In addition, processes for purifying selectively comminuted psyllium seed husk are described.
