Oleander tea: herbal draught of death
Annals of Emergency Medicine
|April 1, 1985
Summary
Oleander tea poisoning caused a fatality, highlighting cross-reactivity with digoxin tests. Digoxin-specific antibodies may offer life-saving treatment for oleander toxicity.
Area of Science:
- Toxicology
- Cardiology
- Pharmacology
Background:
- Oleander (Nerium oleander) contains cardiac glycosides similar to digoxin.
- Plant-derived glycosides can cause severe cardiac arrhythmias and toxicity.
Observation:
- A case study involving a woman who died after consuming oleander herbal tea.
- The patient's presentation demonstrated cross-reactivity between oleander glycosides and digoxin radioimmunoassay.
Findings:
- Oleander glycosides interfere with digoxin testing methods.
- The Na-K ATPase pump inactivation by oleander complicates treatment strategies.
Implications:
- Digoxin-specific Fab antibody fragments are a potential life-saving intervention for oleander poisoning.
- Effective management of oleander toxicity requires controlling arrhythmias and hyperkalemia.

01:14Dehydration of Aldols to Enals: Base-Catalyzed Aldol Condensation
This lesson delves into the aldol condensation catalyzed by bases, where aldols undergo dehydration to enals. As shown in Figure 1, the β-hydroxy aldehyde formed in a base-catalyzed aldol addition reaction dehydrates on heating to yield an unsaturated carbonyl product, which is commonly referred to as an enal.
00:43Dehydration of Aldols to Enones: Acid-Catalyzed Aldol Condensation
As shown in Figure 1, under acidic conditions, the β-hydroxy ketone undergoes dehydration via an E1 elimination reaction to form an enone.
01:17Antidotes
Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:30Toxidromes: Clinical Features
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
01:26Pharmaceutical Poisoning: Treatment Strategies
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
