Toxicology and Poison
Definition of Poison
"All substances are poisons; there is none which is not a poison. The right dose differentiates a poison and a remedy." Paracelsus (1493-1541)
This is a fairly simple statement put in a complex form. Its is stating that all substances can be used to poison someone or used to heal them; its a difference in the quantity of the substance consumed. An example of this is water, if too much is consumed you will get water poisoning and die, but water can cure dehydration and keep you from dying.
Why are poisons difficult to detect?
weakness, headache, burning eyes, nausea, abdominal pain, cough, hyperpigmentation, anemia, and death
Arsenic poisoning is normally diagnosed by the hyperpigmentation that occurs on the main trunk and outer extremities, occasionally collecting in mucus membranes making it visible in the mouth and under the tongue.
