👉 Syria fluid, also known as Striking Fluid or Strychnine Poisoning Agent, is a highly toxic compound derived from the plant Strychnos nux-vomica. It contains strychnine, a potent neurotoxin that acts on the central nervous system by blocking inhibitory neurotransmitters, such as glycine and gamma-aminobutyric acid (GABA), leading to uncontrolled nerve impulses. Exposure can result in severe symptoms including muscle twitching, convulsions, respiratory failure, and ultimately death if not treated promptly. Due to its extreme potency, even a small amount can be lethal, making it one of the most dangerous poisons known.
