'Yào píng' literally combines 'yào' (medicine, drug) and 'píng' (bottle, container), meaning a small bottle used specifically to hold medicine—typically oral pills, liquid medications, or ointments. It is a common household item in Chinese-speaking communities and appears frequently in pharmacies, hospitals, and home first-aid kits.

This compound noun is always written as two characters with no spacing and functions as a countable noun: you can say '一个药瓶' (one medicine bottle), '几个药瓶' (a few medicine bottles), or '空药瓶' (empty medicine bottle). Unlike general containers like '瓶子', '药瓶' implies medical purpose and often has child-resistant caps, dosage labels, or pharmacy-printed instructions in Chinese.
