Arsenic, As, is an element and is poisonous. It was used to treat siphylis. It is used for poison for rodents.
Warfarin sodium or coumadin is used to thin blood and is used in rat poison.

gandyg is almost right. The element is thallium. Rat killers lay out thallium to kill them. One sometimes sees "Treated with thallium" on signs on lawns and subway tracks.
There is an isotope thallium-201. It is radioactive. It decays by a rare mode called electron-capture or K-capture.
Normally, when a nucleus is "short" of neutrons, it decays by emitting a positron (beta plus particle). Positron emission takes the form of conversion of a proton in the nucleus to a proton and the positron.
Thallium-201 decays by sucking an electron from its own K-shell into its nucleus to form a new neutron. The benefit to the patient is that the patient gets the benefit of nuclear medicine without the exposure of ionizing radiation (alpha, beta rays). There is a series of gamma rays generated from the reaction. These gamma rays can be detected and mapped onto a patient's heart.
Thallium forms +1 salts. Thallium ions look to the body just like potassium ions or sodium ions. So doctors get patients onto treadmills, where the patients walk hard. Their hearts beat faster. They are injected with thallium-201. Doctors image their hearts with gamma ray detectors according to how heart muscle absorbs thallium. Heart muscle damaged by heart attacks does not absorb so much thallium.

I think you mean Warfarin...its not an element though, just a molecule. It works by thinning the blood, which is why doses are strictly regulated otherwise hemorrages can occur, athough this is the desired effect when used as poison

Big deal! Some rat baits also contain wheat. That doesn't mean bread is poisonous.

Sodium flouride such as you'd find in tap water and toothpaste is also used in rat poisons.
