What is Fever Nut / Karanj (कँट करंज)?
Kant Karanj (Caesalpinia bonducella) is a thorny climber with feathery leaves and yellow flowers. The seeds are used medicinally and are known as Bonduc nuts. It grows up to 2500 feet altitude in many regions of India. The plant has compound leaves that are bipinnate. The seeds are hard, grey, and round. The seed kernel is extremely bitter and used primarily as an antipyretic (febrifuge). It is particularly effective against intermittent fevers (Vishama Jvara). The oil from seeds, called Hongay oil, is used externally for skin diseases including Scabies and Herpes. The bark is also used in treatment of periodic fevers. Chemical analysis shows Bonducin as the key active principle. Dose: seeds 1-3 ratti; bark decoction 2-4 tola.
