Sabja, commonly referred to as basil seeds or tukmaria, are the seeds derived from the sweet basil plant (Ocimum basilicum). These seeds come from the sweet basil, a culinary herb celebrated for its fragrant leaves. The scientific name for this plant is Ocimum basilicum. Sabja seeds are small, round, and appear black when dry. Upon soaking in water, they form a gelatinous outer layer, resembling the texture of chia seeds.
