Basil seeds, also known as Sabja or Tulsi seeds, are small black seeds derived from the sweet basil plant (Ocimum basilicum). When soaked in water, they swell and develop a gelatinous coating, making them a popular ingredient in drinks and desserts. Rich in fiber, these seeds aid digestion, promote hydration, and help in weight management. They also contain essential nutrients like omega-3 fatty acids, calcium, and magnesium, making them a valuable addition to a healthy diet.
