Poisonous Management

Toxic parts

Whole plant [2]


The whole plant contains calcium oxalate crystals especially in the sap.  It is also contains proteolytic enzymes that can excite histamine release causing serious allergic reaction in sensitive individuals. [2]

Risk management

A. andreanum are unique plants which may help in further enhancing the landscape around the house. However, it can cause adverse effects on pets and children when ingested. It would be wise to place this plant as a second layer plant which would render it inaccessible to pets and out of reach of small children.

Poisonous clinical findings

The leaves and stems of A. andreanum containing minute, sharp crystals, or raphides, of calcium oxalates. If ingested, it causes painful burning and swelling of the lips, mouth, and throat, sometimes to the extent of causing restriction to breathing. Symptoms may include increase salivation, hoarseness, difficulty in swallowing, loss of speech, and loss of appetite. The initial pain from ingestion almost always inhibits further swallowing. The crystals pass unchanged through the digestive tract not causing further complications. The calcium oxalate crystals may cause irritation to the skin and eyes. [6]


In managing the case of Oxalate poisoning, prehospital and emergency department care could be taken. [2][8]

Pre-hospital care:

  1. Remove all traces of plant material from areas contaminated with it i.e. mouth, eye and skin, immediately. Rescuers should ensure they are protected from contact with these plant materials.
  2. Exposed areas should be copiously irrigates with water.
  3. If ingested, the mouth should be repeatedly rinsed with cool water or a demulcent.
  4. Provide analgesics if pain is severe.

Emergency Department care:

  1. Oral exposure – Asses airway for any signs of compromise. Those without compromised airway can be given cold liquids, crushed ice or ice cream for relief. Keeping or swishing antihistamine liquid like diphenhydramine in the mouth can provide local anaesthetic and antihistaminic effects. Those with evidence of laryngeal oedema can be treated with antihistamines and observed or better admitted until oedema subsides.
  2. Eye exposures – Copious irrigation with water. Rule out corneal involvement by performing slit-lap examination with fluorescein staining.
  3. Skin exposures – Washing with soap and water suffice, and local wound care it there exist any wounds. Some people may develop contact dermatitis.
