Terpenoids, saponins, insoluble oxalates
While this plant does contain toxic substances, the most common effects seen are loss of appetite, mild vomiting and diarrhea. In isolated casess ataxia and leucopenia (low white blood cell count) have been reported.
Brassaia actinophylla (syn. Schefflera actinophylla), also known as Schefflera, Umbrella Tree, Octopus Tree, and Australian Ivy Palm is a decorative evergreen tree commonly grown in mild to warm climates. Capable of growing to heights of 50 feet, its use is typically limited to larger gardens and/or use as a landscape decoration. The plant is prized for the thousands of dull red flowers it produces when in bloom, a process that begins in early summer and continues for several months. Aside from being a colorful addition to the landscape the flowers produce large amounts a nectar which in turn attract a wide variety of honey eating birds and other animals with an inherent sweet tooth adding wildlife to the landscape. It is, however, an aggressive plant and its roots can dominate surrounding soil. In some areas (e.g., Florida & Hawaii USA) it is considered to be an invasive weed and therefore planting is highly unadvised.
The plant should be considered toxic as it does contain terpenoids, saponic glycosides (saponins), and unknown insoluble oxalates. The effects of ingestion, however, seem limited and the most commonly reported symptoms are loss of appetite and gastrointestinal upset (vomiting & diarrhea). In an isolated case involving a poodle, the animal experienced the aforementioned symptoms with the addition of ataxia and leucopenia (Spoerke and Smolinske 1990). The available literature reports no fatalities of companion animals from the ingestion of Brassaia actinophylla. As such it should be considered toxix, but most likely not life threateningly so.

Emergency Response and Decontamination
- Initial Action: Avoid further ingestion of the plant and consult a veterinarian.
- Mouth Clearing: If ingestion was recent, remove any remaining plant matter and flush the mouth thoroughly with water.
- Inducing Vomiting: While pets often vomit spontaneously to expel non-digestible material, if vomiting does not occur, it may be induced using 3% hydrogen peroxide at a dose of 1 teaspoon per 10 lbs of body weight.
- Clinical Decontamination: Activated medical charcoal may be useful for absorbing toxins. If a large quantity of plant material was ingested, gastric lavage may be beneficial to empty the stomach contents.
Symptomatic Care and Gastrointestinal Management
- Hydration: Ensure the pet receives plenty of fluids to prevent dehydration resulting from diarrhea.
- Gastrointestinal Protection:
- Kapectolin: Administer 1 to 2 ml/kg four times a day to coat and protect the stomach lining.
- Sucralfate: Acts as a barrier against gastric acid to reduce intestinal irritation.
- Dogs > 60 lbs: 1g every 6 to 8 hours.
- Dogs < 60 lbs: 0.5g every 6 to 8 hours.
- Cats: 0.25g every 8 to 12 hours.
Risk Assessment and Prognosis
- Clinical Outlook: Serious intoxications are exceptionally rare; symptoms are generally limited to mild gastrointestinal upset (vomiting and diarrhea).
- Primary Threat: While fatalities are basically unheard of, the most serious threat is the potential for an extreme allergic reaction to the plant's irritant toxins.
- Recovery: With symptomatic care, most animals make a full recovery within a few hours to a few days.
