I read that a bacteriostat can help prevent infections in wounds.

Really? How does it work?

It inhibits bacterial growth, so it keeps the area clean.

That sounds useful! I should keep some on hand for emergencies.

Root Explanation

Bacteriostat → It is formed from "bacterium" (from Greek "bakterion", meaning rod or staff, referring to the shape of certain bacteria) and "-stat" (from Greek "statos", meaning standing or stationary). The word describes a substance that inhibits the growth of bacteria, effectively keeping them in a stationary state.

Memory Tip

Think of 'bacterium' referring to a 'rod-shaped' organism and '-stat' meaning 'standing still' — a bacteriostat is something that keeps bacteria from growing.
