poison strychnine

Strychnine is a toxic chemical that affects the nervous system by blocking the normal signals that control muscle movement. When ingested, it causes severe, uncontrollable muscle contractions, leading to intense pain, difficulty breathing, and potentially death due to muscle paralysis or exhaustion. Historically used as a pesticide, it is highly poisonous to humans and animals. Because of its danger, strychnine is strictly regulated and not used in consumer products. Exposure requires immediate medical attention to manage symptoms and prevent fatal outcomes.
