Jamun seeds are well known to have anti-diabetic nature mainly in lowering the blood sugar levels. The seeds are also even known to lower the complications caused by diabetes like cataracts and neuropathy.

In a study conducted, oral administration of alcoholic extract of Jamun seeds at a dose of 100mg kg-1 body weight on alloxan-induced diabetic rats had shown a significant reduction in blood glucose and urine sugars (3).

Several other studies had also shown that Jamun seed extracts have hypoglycemic activity and also said that the extract can be even more effective than Glibenclamide, a standard antidiabetic drug (4).

Fruit pulp can reduce blood sugar levels

The fruit pulp of Jamun may also help you in decreasing your blood sugar levels and can also act as a nephroprotective agent (5).

The study said water extract is effective than ethanolic extract and also said that insulin production in the treated animals is two and half times more than untreated ones (6).
