'Yào chí' literally means 'medicine spoon' — a small, often plastic or stainless steel spoon used specifically for measuring and administering liquid or powdered medicine. The character 药 (yào) means 'medicine' or 'drug', while 匙 (chí) means 'spoon'. Unlike regular dining spoons, a yào chí typically has calibrated markings (e.g., 2.5 mL, 5 mL) to ensure accurate dosing, making it essential in home healthcare, pharmacies, and pediatric care.

This tool is especially common when giving oral medications to children or elderly patients who cannot swallow pills easily. It’s frequently included in first-aid kits and prescribed with liquid antibiotics, cough syrups, or vitamin supplements. Though sometimes informally called just 'a medicine spoon', the term 药匙 carries a precise, functional connotation in medical contexts and is rarely used metaphorically or outside health-related settings.
