Guar (Cyamopsis Tetragonaloba L.) is a native plant of India and can now be found in Pakistan, USA, Africa and Australia.

In India, Guar is considered a potential source of unconventional livestock feed.

Guar gum is a portion of endosperm of Cyamoposis tetragonolobus L.

Guar Gum has been used by the food industry as a thickener, stabilizer in emulsions due to its excellent dough properties.

Many interesting properties, including antioxidant activity, hypocholesterolemic and prebiotic activity have been attributed by the scientific literature to this compound.

In particular, hepatoprotective activity (1) and drug release have been studied (2).

At high concentrations it can cause flatulence and swelling due to the fermentation of intestinal flora.
