Compare with Definitions

Poison

In biology, poisons are substances that can cause death, injury or harm to organs, tissues, cells, and DNA usually by chemical reactions or other activity on the molecular scales, when an organism is exposed to a sufficient quantity.In a metaphorical broader use of term it may refer to any thing deemed harmful. The fields of medicine (particularly veterinary) and zoology often distinguish a poison from a toxin, and from a venom.

Toxin

A toxin is a harmful substance produced within living cells or organisms; synthetic toxicants created by artificial processes are thus excluded. The term was first used by organic chemist Ludwig Brieger (1849–1919), derived from the word toxic.Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors.

A substance that causes injury, illness, or death, especially by chemical means.
