I heard that some creams can act as a rubefacient for sore muscles.

Really? I didn't know that! How does it work?

Root Explanation
Rubefacient → It is formed from "rubeo" (meaning to be red) and "facere" (meaning to make or do). The word describes a substance that causes redness of the skin.
Memory Tip
Think of something that 'makes' ('facere') your skin 'red' ('rubeo') — that's why rubefacient refers to a substance that causes redness.
