Name of Drug

Syzygii cumini semen, jambolan seed.

Composition of Drug

Jambolan seed consists of the dried seed of Syzygium cumini (L.) Skeels (syn. S. jambolana (Lam.) de Candolle) [Fam. Myrtaceae], as well as preparations thereof.


Jambolan seed is used for diabetes and also in combination preparations for atonic and spastic constipation, diseases of the pancreas, gastric and pancreatic complaints, nervous disorders, depression and exhaustion. It is also used as a carminative, antispasmodic, stomachic, roborant, and aphrodisiac.

The effectiveness for the claimed applications has not been documented.


The therapeutic use of jambolan seed for the various forms of diabetes cannot be justified because of other established therapeutic possibilities.


The blood sugar-lowering effect of jambolan seed is uncertain and could not be established by several researchers.
