History of poison

The history of poisons stretches over a period from before 4500 BC to the present day. Poisons have been used for many purposes across the span of human existence as weapons, anti-venoms and medicines. Indeed, poison has allowed much progress in the branches of medicine, toxicology, and technology, among others.
The use of poison varies greatly. Historically, its employment in assassination and homicide incited fear in the public. Other times, it has been used for political implosion and elements of
espionage.
In the present day, poison is still used for a variety of mostly mundane purposes involving
agriculture and food preservation, but is also still used for the starker purposes of murder. Due to more modern-day technology, however, poisons can be more easily detected.
