convulsant

Causes violent contractions

A convulsant is a substance that induces convulsions—violent, involuntary muscle contractions.

The term appears mainly in medical and pharmacological contexts, where convulsant agents are used in research or, historically, in psychiatric treatment.

As an adjective, convulsant describes something capable of causing seizures: convulsant drugs, convulsant effects.
