Kalonji or Kala jeera is also known as Upakunci in Ayurveda. It has a characteristic taste and flavor and is used in various cuisines. Kalonji helps to keep blood sugar levels in check and is good for diabetics due to its hypoglycemic (blood sugar lowering) activity. Adding Kalonji seeds to food acts as a digestive aid and prevents gas and flatulence due to its carminative property. Kalonji also helps in maintaining a balance between good and bad cholesterol levels due to its antioxidant activity. It might also help in weight management as it increases the metabolism of the body.
