Guar gum is a dietary fiber obtained from the endosperm of the seeds of the Indian cluster bean (Cyanopsis tetragonolobus) of the family Leguminosae. The guar plant is a pod bearing, nitrogen-fixing legume, which has been grown for centuries in India and Pakistan, where it is one of the principal crops and is used as food for both humans and animals. It is now being grown in America for use in various industries (food, cosmetic and paper industries) (37).
