Health & Culinary Benefits of Jeera (Cumin Seeds) 1. Superior Digestive Aid Jeera is famous for its ability to calm the stomach. It contains an active compound called thymol, which stimulates the secretion of digestive enzymes, bile, and acids. Reduces Bloating: It helps speed up digestion, preventing food from lingering in the gut and causing gas. Jeera Water (Jal): Drinking water boiled with cumin seeds is a time-tested remedy for relieving morning sickness, indigestion, and stomach cramps. 2. Rich Source of Dietary Iron Iron deficiency (anemia) is a widespread nutritional concern. Jeera is naturally incredibly rich in iron. Just one teaspoon of cumin powder provides roughly 1.4 mg of iron, which is about 17.5% of the daily recommended intake for adults.
