Nicander was a Greek poet and physician. His Theriaca, in 958 hexameters, dealt with the symptoms and treatment of poisoning by the bites of poisonous animals; the Alexipharmaca considered intoxications through animal, vegetable, and mineral poisoning, and their suitable antidotes. Nicander was also the first writer to mention the medicinal use of the leech. The above work has a Greek text, and is one of the few medical incunabula issued by Aldus Manutius of Venice. A Latin translation appeared at Cologne in 1531. See Nicander: The Poems and Poetical Fragments edited by A. S. F. Gow and A. F. Scholfield.(Cambridge, 1953), and also P. K. Knoefel & M. C. Covi, A Hellenistic Treatise on Poisonous Animals (The "Theriaca" of Nicander of Colophon): A Contribution to the History of Toxicology (1991).

Nicander's works were first published in print by Aldus Manutius together with the first edition in Greek of Dioscorides, De materia medica, and two works on venoms by "Pseudo Dioscorides" ISTC No: id00260000. Digital facsimile from Bayerisches Staatsbibliothek at this link
