Black jamun (Scientific name – Syzygium cumini) also known as “Naaval pazham” in Tamil or Jambul or Jambolan has been used to treat diabetes for a long time now. This fruit has a unique taste and can be consumed just as a fruit too. But the remedy explained here as better effects for diabetes. This remedy can also work for those with Gestational diabetes.
Jamun is most often recognized as an adjuvant therapy in type-2 diabetes. This has been traced not only to its anthocyanin-rich, dark-purple fleshy pulp, but also to its seeds, which have been most studied for their antidiabetic principles. (Swami, Thakor, Patil, & Haldankar, 2012)

Jamun fruit reduces the sugar in the blood and is very good in the control of diabetes. Its seeds contain Glucoside, Jamboline and Ellagic acid, which are reported to have the ability to check the conversion of starch into sugar in case of excess production of glucose.
