The use of "poison" as an adjective ("poisonous") dates from the 1520s. Using the word "poison" with plant names dates from the 18th century. The term "poison ivy", for example, was first used in 1784 and the term "poison oak" was first used in 1743. The term "poison gas" was first used in 1915. [9]
Only a few modern mammal species are capable of producing venom; they are likely the last living examples of what was once a more common trait among the mammals. The definition of "venomous" becomes less distinct here, however, and whether some species are truly venomous is still debated. European mole (Talpa europaea)
The word toxin does not specify method of delivery (as opposed to venom, a toxin delivered via a bite, sting, etc.). Poison is a related but broader term that encompasses both toxins and toxicants; poisons may enter the body through any means - typically inhalation, ingestion, or skin absorption.

Here’s the differences between the South Carolina critters that are poisonous and those that are venomous.

[1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
Some species in this poison frog family (particularly Dendrobates, Epipedobates, and Phyllobates) are conspicuously coloured and sequester one of the most toxic alkaloids among all living species. [ 21 ] [ 22 ] Within the same family, there are also cryptic frogs (such as Colostethus and Mannophryne ) that lack these toxic alkaloids.
The word toxicology (/ ˌ t ɒ k s ɪ ˈ k ɒ l ə dʒ i /) is a neoclassical compound from Neo-Latin, first attested c. 1799, [3] from the combining forms toxico-+ -logy, which in turn come from the Ancient Greek words τοξικός toxikos, "poisonous", and λόγος logos, "subject matter").
By contrast, a toxin is a poison produced naturally by an organism (e.g. plant, animal, insect). [2] The 2011 book A Textbook of Modern Toxicology states, "A toxin is a toxicant that is produced by a living organism and is not used as a synonym for toxicant—all toxins are toxicants, but not all toxicants are toxins.
