Residual poison or pernicious influence remaining from a past evil or disaster.

How it's used

Primarily used in metaphorical contexts to describe the lingering negative effects of a past ideology, system, or trauma. It carries a strong sense of something harmful that persists even after the main source has been removed. While it can refer to literal toxins in a medical sense, it is far more common in social or political commentary.

Examples

This kind of thinking still has a pernicious influence.
Haven't you cleared out all the residual poison yet?

Common phrases

to clear away residual influence
pernicious influence of an ideology

Common mistake

Do not confuse this with 毒素, which refers to physical toxins or biological poisons. Using 餘毒 to describe a simple food poisoning case will sound overly dramatic or confusingly abstract.
