What Is Oleander Poisoning

Introduction

Oleander poisoning is a serious medical condition resulting from exposure to the toxic chemicals present in the leaves, flowers, and stems of the oleander plant (Nerium oleander). This evergreen shrub, native to Mediterranean regions, is cultivated for its ornamental beauty and is commonly found in gardens, parks, and landscapes throughout the United Kingdom.¹

Definition of oleander poisoning

Oleander poisoning refers to the harmful effects caused by the ingestion, inhalation, or skin contact with the toxic components of the oleander plant. Oleander contains cardiac glycosides, such as oleandrin and digitoxigenin, which can have damaging effects on the heart, nervous system, and various organs if absorbed into the body.¹

Common sources of oleander poisoning

Oleander poisoning most commonly occurs when individuals mistakenly consume parts of the oleander plant, either accidentally or with the intent to harm oneself or others. Ingesting any part of the oleander plant, including the leaves, flowers, bark, or stems, can lead to poisoning. Additionally, burning oleander wood or inhaling its smoke can also result in toxic exposure. It is important to note that even small amounts of oleander can be highly toxic and potentially fatal.²

Importance of understanding oleander poisoning

Understanding the dangers associated with oleander poisoning is crucial for both the general public and medical professionals. Adequate knowledge about oleander poisoning can help individuals recognize potential sources of exposure, take appropriate precautions, and seek immediate medical assistance in case of ingestion or exposure. Additionally, medical practitioners should be aware of the symptoms and treatment options to provide prompt and effective care in emergency situations.

What is oleander?

Oleander, also known as Nerium oleander, is an evergreen shrub that is native to the Mediterranean region. It is highly regarded for its beautiful flowers, which bloom in various colors such as white, pink, and red. However, it is important to note that while oleander is aesthetically pleasing, it is also highly toxic.²

The toxicity of oleander can be attributed to the presence of various cardiac glycosides, including oleandrin and nerium. These compounds can negatively affect the heart, leading to symptoms such as irregular heart rhythms, low blood pressure, and even cardiac arrest.³

It is crucial to handle oleander with caution as all parts of the plant, including the flowers, leaves, stems, and even the sap, contain toxic substances. Ingesting any part of the plant can lead to severe poisoning, which can be fatal if not treated promptly.

Symptoms of oleander poisoning

If someone has ingested or come into contact with oleander, it is important to be aware of the potential symptoms of oleander poisoning. The symptoms can vary depending on the amount of exposure and the person's overall health.⁴

Following is a list of symptoms that manifest after the ingestion of the toxins:

• Nausea
• Vomiting
• Abdominal pain
• Diarrhea

In addition to gastrointestinal symptoms, oleander poisoning can affect the cardiovascular system lading to the manifestation of the following:

• Arrhythmias (irregular heartbeat rhythms)
• Bradycardia (Slowed heartbeat)
• Dizziness
• Fainting
• Shortness of breath

Respiratory symptoms can also manifest in cases of oleander poisoning. Inhaling the smoke from burning oleander plants can irritate the respiratory tract and lead to the following:

• Coughing
• Wheezing
• Difficulty breathing
• Respiratory distress
• Respiratory failure

In some instances, oleander poisoning may result in neurological symptoms. These can include:
