Something that is harmful or damaging to the liver.
Certain medications can be hepatotoxic and may cause liver damage if taken in high doses.
Hepatotoxic is formed from "hepaton" (from Greek "hēpar", meaning liver) and "toxic" (from Latin "toxicum", meaning poison). The word describes substances that are poisonous to the liver.
Think of 'liver' ('hepaton') being affected by 'poison' ('toxic') — that's why hepatotoxic refers to something harmful to the liver.
