Introduction
Cold-pressed sesame oil is a cherished product derived from the seeds of the sesame plant (Sesamum indicum). Renowned for its rich flavor and diverse applications, this oil has a long-standing history intertwined with various cultures around the globe. From culinary uses to its significance in traditional medicine and aromatherapy, cold-pressed sesame oil has earned its place in both kitchens and wellness practices.

What Is Cold-Pressed Sesame Oil?
