Historically used as a hunting poison by indigenous South American tribes, curare is an alkaloid mixture that causes muscle paralysis when it enters the bloodstream. This potent plant extract, known for its ability to immobilize prey, operates by disrupting the communication between nerves and muscles, directly answering the question: does curare paralyze you?

Oleander (Nerium oleander) is one of the most toxic plants in the world, with all parts of the plant containing potent cardiac glycosides. While it is a dangerous poison, the toxins in oleander do not typically show up on standard drug tests, but they can trigger a false positive result on specific therapeutic drug monitoring assays, particularly those for the heart medication digoxin. This distinction is crucial for both clinical and forensic contexts.

The Centers for Disease Control and Prevention (CDC) classifies ricin as a Category B bioterrorism agent, highlighting its lethal potential as a poison found naturally in castor beans. While the castor oil plant is the source, it is crucial to understand the distinct difference between the highly toxic seeds and the purified, safe-to-use oil that is extracted and processed.

While most common poisonings have effective treatments, a few deadly substances, like the radioactive element Polonium-210, lack a specific antidote, making treatment extremely difficult. In the field of Medications and Pharmacology, the concept of a poison with no cure is complex and points to the critical importance of immediate, comprehensive medical intervention.

While historically arsenic was famously nicknamed the "king of poisons" for its insidious use in assassinations, modern toxicology reveals a different answer for **what is the king of all poisons?** The title for the most potent known substance by weight now belongs to a bacterial neurotoxin called botulinum.

Historically a notorious poison, arsenic has a unique regulatory status within pharmacology and is notably **not** classified as a controlled substance under the Drug Enforcement Administration's (DEA) schedule. A specific formulation, however, serves as a modern, prescription medication for certain cancers.

Originally derived from the *Strychnos nux-vomica* tree, strychnine was historically employed for a variety of purposes before its extreme toxicity was fully understood. Exploring what was strychnine used for reveals a startling and cautionary tale in the annals of pharmacology and toxicology.
