The Sago palms have been here since the age of dinosaurs and have survived them and so many other generations. The low maintenance allows them to outlive many civilizations. These are also called Cycas revoluta, which are small, about 3 to 20 ft tall and 2 to 12 ft wide.
The plant is old and has originated in the subtropical climate of southeast Asia. However, due to its beauty and successful management on its own, the plant is popular in the US, especially in areas with hardiness zone 8, such as Florida.
The appearance of the Sago’s palm is bluish-green leaves that have a bit of rough texture along with a brown stem that is thick and stubby. Female palms additionally produce a cone that yearly reproduces seed. To reproduce, you must have both opposite-sex plants to go through pollination.
As mentioned earlier, for outdoor planting of Sago’s palms, you must live in areas with minimum winter temperature in the hardiness zones of 8 and above. In these areas, plants thrive all year despite weather conditions.
Although plants are the natural devices to clean the air and make it abundant in oxygen, and the plant extracts can be used for various purposes such as medicines, etc., their ingestion can be dangerous for living beings.
Are Cycads Poisonous to Humans?
Yes. A neurotoxin is a component of the plant composition that is harmful, toxic, and poisonous to humans and pets. This is abundantly found in Cycad palms.
This post will cover the Sago palms’ toxicity and how to prevent and treat it.
How Does It Spread?
The spread of the poisoning is only possible through ingestion, so it is unlikely that touching it would be dangerous. Even though touching may not be dangerous, always wear gloves to protect your fingers from the pointed fronds.
Cycads are plants that have all the parts which contain toxic poisons. Seeds of the cycads are more toxic than all other parts, though; since the seed is tiny, most pets digest it and get poisoned. The seeds are small ready-to-eat bits for dogs and other pets.
How To Kill a Cycad Palm?
The plant is quite tall and sturdy; it isn’t easy to cut it down. You will need a chainsaw. After using it, make several holes using a drill in the stump, then use potent glyphosate, which acts as a herbicide, and fill it in the holes, ensuring that the roots are dead to the core.
The best way to perform this task is to use protective gear, and after you are done, always clean the cutting equipment.
People usually ask if it is safe to burn the leaves and the Cycad debris. The main issue with burning a plant is that it increases the carbon in the air. Secondly, since the cycad palms are also toxic, burning their remnants will only release the toxins in the gaseous form, which is quite harmful because now all living beings would breathe in that air.
Instead of burning the debris, it is better to pack it up in a plastic bag and then deliver it to a landfill site.
How To Detect Whether You Have Cycad Poisoning?

If it is affected, the other body parts fail first, such as the blood will not clot on its own, so if you get a cut, it will bleed and not heal.
Furthermore, cytosine in the body can also affect the gums, making them sensitive and bleeding. Similarly, nosebleeds are a common occurrence of liver failure as well. In case of internal bleeding, the person could die before it is detected.
When the blood is not detoxified, it is because the liver is not functioning well. The symptoms that come after some time due to cytosine include wobbly ambulation, weakness, seizures, tremors, etc.
Then there are some other such as abdominal fluid accumulating and causing swelling, skin and the gums becoming yellow, stomach pain, frequent urination, depression, bruising, paralysis, coma, lethargy, and black-colored feces.
How To Diagnose the Sago Palm Toxicity?
There is no specific analysis to detect the toxicity and identify the presence of cytosine. Furthermore, you can also not identify the amount of plant and the percentage of toxin in the body or how much it has affected it.
