Determining the single **most natural poison in the world** is often a matter of defining what 'most' means in terms of toxicity. According to some scientific measures, botulinum toxin, produced by the *Clostridium botulinum* bacterium, is considered one of the most potent substances found in nature. However, the danger posed by a natural poison depends on various factors beyond just its inherent toxicity.

Affecting only about 59 people per million, the medical abbreviation 'AEO' most commonly refers to Apraxia of Eyelid Opening, a rare neurological movement disorder. However, confusion can arise as the same acronym is used for other distinct medical conditions, necessitating a professional diagnosis to identify the correct affliction and treatment approach.

By some estimates, botulinum toxin is over 100,000 times more potent than ricin, making it the most lethal substance known on a per-weight basis. Understanding **what is the most lethal toxin to humans?** reveals a surprising intersection of bioterrorism concerns and modern medicine.

While botulinum toxin is widely cited as the most acutely toxic substance known to humans, the answer to the question "What is the most harmful substance to humans?" is far more complex when considering factors like widespread exposure, addiction, and public health impact.

It's a common misconception that Botox comes from an animal, but the truth is far more microbiological. The core component of Botox is a neurotoxin produced by the bacterium *Clostridium botulinum*, which is found naturally in soil, lakes, and forests. This powerful neurotoxin undergoes an extensive purification and dilution process to become the safe, therapeutic product used in aesthetic and medical fields today.

With a median lethal dose (LD50) of approximately 1 nanogram per kilogram of body weight, botulinum neurotoxin is the most potent toxin known to science. This incredibly deadly substance, produced by the bacterium *Clostridium botulinum*, has fascinated scientists for centuries due to its extreme power and dual nature as both a lethal poison and a valuable medical tool.

With an estimated lethal dose ($LD_{50}$) for humans measured in tiny fractions of a gram, the botulinum toxin is the undisputed answer to the question, **what is the most toxic toxin in the world?** Produced by the bacterium *Clostridium botulinum*, this potent neurotoxin attacks the nervous system and causes a rare but potentially fatal paralytic illness.

By a measure of lethality, botulinum toxin is considered the most toxic substance known to science, far surpassing notorious killers like arsenic or cyanide. To understand why, it is important to first ask, "What is the strongest poison?" and look at the metric scientists use to compare toxicity.
