Basil seeds, also known as Sabja seeds or Tukmaria seeds, are small black seeds derived from the basil plant, scientifically known as Ocimum basilicum. Basil is a popular herb used in various culinary dishes, but its seeds have gained attention for their nutritional and health benefits.

Basil seeds are tiny, oval-shaped seeds with a black outer coat. When soaked in water, they swell up and form a gel-like outer layer, similar to chia seeds. This gelatinous texture is due to the presence of soluble fiber in the seed's outer layer.
