This tool is commonly used in cooking to prepare spices, herbs, and other ingredients. In addition to culinary uses, mortars and pestles are also employed in laboratories for grinding chemicals and in traditional medicine for preparing herbal remedies. They have been used for thousands of years across various cultures, making them a timeless and essential tool in both kitchens and apothecaries.
