Guargum, also known as cluster bean is an extract of the guar bean, where it acts as a food and water store. The guar bean is mainly grown in India and Pakistan. Smaller crops are grown in the U.S., Australia, China, and Africa. It is a drought-resistant crop and can be eaten as a green bean, fed to cattle, or used in green manure.

Guar is a rain-fed crop and is sown in July-August and harvested in October-November. It is a leguminous crop, and therefore fixes nitrogen, making the soil fertile.
