The Crown of Thorns is a flowering plant species belonging to the spurge genus in the family Euphorbiaceae. It is also known by the popular names Christ thorn and Christ plant.
The connection to Christ is based on the biblical account of Jesus wearing a woven crown of thorns during the events leading up to his crucifixion. The crown was formed from the plant’s stalks.
On the other hand, the botanical name, Euphorbia milii, honors Baron Milius, the person who brought it to France at the beginning of the 19th century.
In Latin America and Brazil, it is known as Corona de Cristo and Coroa-de-Cristo, respectively.
It is a succulent that is native to Madagascar and is one of the few that has real leaves. because of its simple growth and bright, brilliant flowers that bloom virtually all year long, both inside and outside.
Although Christ thorn thrives in warm climates, it can be grown indoors in colder climates and is hardy in zones 9 to 11 in the United States.
Is Crown of Thorns A Poisonous or Toxic Plant?
Despite the fact that Euphorbia milii is typically regarded as a perfect houseplant. However, you must use caution if you are growing this species indoors, especially if you have kids or pets, as it contains deadly phorbol esters.
Additionally slightly poisonous, the produced sticky sap is known to irritate the skin and eyes.
What Parts Of Euphorbia Milii Are Toxic?
Ingesting any part of the Christ thorn can poison both people and animals.
Additionally, the plant’s damaged stems and leaves generate a sticky, milky fluid that includes corrosive compounds and irritants, so handling it requires extra caution.
What Are The Symptoms Of Poisoning?
The main symptoms of crown of thorns poisoning are throat and mouth irritation or blistering, excruciating stomach or abdominal discomfort, and vomiting.
Other signs that can affect both people and animals include emesis, increased salivation, weakness, and diarrhea.
The irritating sap produces dermatitis and edema when it comes in touch with the skin and eyes, respectively.
If sap accidentally gets into your eye, rinse it out right away with water and seek medical attention if it doesn’t improve within 15 minutes.
Horses who are exposed to Euphorbia milii may get severe blistering and an ankle hair loss.
How To Protect Yourself While Handling Crown of Thorns
It is advised to wear gloves and remove them right away after handling Euphorbia milii in order to avoid coming into contact with the sap.
Additionally, take care not to touch your body while working with the plant, especially your eyes.
Although the majority of animals are not drawn to this variety of Euphorbia, livestock animals do find it tolerable.
When they are starving and are not given access to their usual diet, pets and cattle animals may consume the leaves of the crown of thorns.
Is the plant known as “crown of thorns” toxic to people?
A succulent, cactus-like plant with thorns, the crown of thorns (Euphorbia milii), is indigenous to Madagascar. It makes for a perfect houseplant because of its ability to withstand warm temperatures all year long. In Florida and other Southern states, it is also planted as a garden flower. The name derives from a folktale connecting the plant to the thorny crown Christ wore in the Bible. The plant possesses half-inch-long, sharply pointed thorns. Normal height is between one and two feet (30–60 centimeters), however consistently warm weather might increase this. Typically, the blossoms are vivid red, pink, or white. Crown of thorns flowers bloom in a cyathium, a group of male and female flowers that are only partially grown, like all other Euphorbia family members. The cyathium in E. milii is composed of a cluster of short stems encircled by two large bracts that resemble petals.
The spurge-like euphorbia species are poisonous to both people and animals. Any part of the cut plant can produce symptoms, but the milky white secretion known as latex contains the highest concentration of poisonous compounds. Phorbol esters, a substance that can influence the body’s creation of proteins and enzymes, have been identified as one of the toxins. Ingestion of the latex causes gastrointestinal distress with vomiting and bloody diarrhea, while skin contact with the latex irritates the skin. Additionally, phorbol esters have cancer-causing qualities that encourage the growth of tumors. Dogs find the bitter taste of crown of thorns repulsive, making ingestion uncommon. The thorns also serve to deter animals from approaching too closely. Although care should be taken to prevent infection, a skin wound from one of the thorns won’t poison you. Broken stems or leaves with sap leaks, however, can irritate the skin and lead to dermatitis when contacted. The mucous membranes of the mouth, eyes, and nose are most painfully affected, and severe eye exposure can result in blindness and visual loss.
In cooler areas, the southern garden plant known as “crown of thorns” is frequently grown indoors. A milky white fluid from the plant is poisonous to both people and dogs. Dermatitis and irritation are brought on by skin contact. Ingestion is linked to gastrointestinal problems.
What occurs if you consume Euphorbia?
Euphorbia, or spurge, has more than a hundred different species. The juice or sap from any of these species is so acidic that it could corrode and cause skin ulcers upon touch.
Poisonous Properties
Euphorbia or spurge species all have a milky liquid that is generally toxic and bitter. Extreme irritability, inflammation, ulceration, and in rare cases gangrene are brought on by contact with the skin.
Country people frequently use the fruits of the caper spurge (E. lathyrus), which has an acrid, emetic, and highly purgative milky juice, as a purgative.
Symptoms
Spurges irritate the mucous membrane when consumed (swallowed), especially in the back of the mouth. After consuming the plant, there is painful vomiting that lasts for 45–120 minutes, or even longer. This is followed by diarrhea and a low body temperature. There will also be anxious symptoms, vertigo, delirium, muscle spasms, circulation issues, and excessive sweating if the amount consumed was sufficient.
Additionally, there could be loss of appetite, colic, cramps, bloating, fever, heart palpitations, and loss of consciousness. Superpurgation and enteritis symptoms prevail in a fatal dose, however they are also accompanied by nervous system symptoms and cardiovascular issues.
Which types of thorns are lethal?
There aren’t many plants with toxic thorns in North America. The Solanum (nightshade) genus contains thorny plants that are also said to have poisonous thorns that cause wounds to heal slowly. The nightshade family (Solanaceae) has various plants with poisonous elements, including leaves, stems, berries, roots, and seeds, which can seriously irritate mammals. This family’s members are dispersed far over North America.
Stinging nettles are a different class of plants that have deadly “thorns.” On the underside of their leaves, they feature tiny hairs that, when brushed against, “sting,” irritate the skin and give off a burning sensation.
The majority of thorny plants can also mechanically hurt people, and in some cases, those injuries lead to thorn fragments breaking off in the skin. Although it can appear that these plants are poisonous, the swelling and redness that surround a wound are actually brought on by an embedded foreign body.
In terms of plants found outside of North America, Gymnosporia buxifolia and Dichrostachys spp. are two examples of African plants with venomous thorns.
My knowledge on prickly plants came from the Botanical Dermatology Database. If you want to learn more about the effects of plants with thorns, there is a wealth of material online.

Can you eat crown of thorns?
Crown-of-thorn Starfish reproduce by widely dispersed spawning. This activity indicates that the species’ male and female both discharge eggs and sperm into the water column at the same time. Fertilized eggs slide into the reef’s minuscule cracks, where they can find some protection from ravenous predators.
If the starfish are taken out of the water, their spines will sag and become flat. In actuality, the body’s exterior breaks down and leaks, discharging bodily fluid. It’s interesting to note that if they are returned to the water while still alive, they completely regain their tubular features and crown-like shape.
Their population fluctuates frequently with coral generation, ranging from high to low densities. Although crown-of-thorns cannot be consumed by humans, scientists are keeping an eye on their environmental impact since their abundance in some locations poses a hazard to other species.
Do crown of thorns plants grow indoors?
Crown of thorns, also known as Christ plant or Christ thorn, is a blooming plant that is native to Madagascar. Baron Pierre Bernard Milius, who was the ruler of the island of Runion in the western Indian Ocean at the time, brought the plant to France around the beginning of the nineteenth century. The spurge family, also known as the Euphorbiaceae, which includes numerous succulent plant species, includes the crown of thorns. Crown of thorns are a low-maintenance, adaptable plant that may flourish both indoors and outdoors (in USDA Hardiness Zones 911).
Green leaves and tiny, vibrant blooms are features of crown of thorn plants. A milky sap is released when the plant’s sharp, prickly stems and branches are damaged. You should be aware that crown of thorns have a high level of toxicity and can be dangerous to both animals and people if consumed if you’re thinking of keeping one indoors.
Is a plant called a “crown of thorns” lucky?
Along with its religious importance, the Crown of Thorns has a well-known, deeply ingrained good luck connotation. As a result, those who cultivate the plant ought to enjoy constant good fortune. The Crown of Thorns plant thrives in a sunny environment.
Is touching euphorbia poisonous?
The milky secretion of the Euphorbia plant, sometimes known as latex, is extremely poisonous and irritating to the skin and eyes. This study provides an illustration of the range of ocular inflammation brought on by unintentional ingestion of Euphorbia plant latex. Three patients came in with recently developed accidental ocular exposure to milky sap of a Euphorbia species. In all cases, there was a significant burning sensation along with vision blur. Visual acuity decreased to counting fingers from 20/60. Clinical findings ranged from anterior uveitis to secondary increased intraocular pressure, mild to severe corneal edema, epithelial defects, and keratoconjunctivitis. With active supportive treatment, all symptoms and indicators disappeared after 10 to 14 days. When handling euphorbia plants, wear safety goggles. Asking the patient to bring a sample of the plant for identification is usually advisable.
Trees, succulents, and herbaceous plants all belong to the Euphorbiaceae genus.
[1] There are numerous kinds of Euphorbia that can be found growing in the wild or in gardens or homes as cultivated examples. The milky sap or latex is poisonous and can cause severe skin and eye problems. From moderate conjunctivitis to severe kerato-uveitis, ocular toxic response can vary [2]. There are a few case reports of people losing their sight permanently as a result of accidentally putting Euphorbia sap in their eyes. [24] Corneal involvement typically proceeds in a predictable order, with edema getting worse and epithelial sloughing on the second day. [3,5] Some species are thought to be more poisonous than others. [6] The inflammation usually goes away without leaving any aftereffects when it is promptly treated and carefully maintained. Here, we show three instances of ocular toxicity brought on by three distinct Euphorbia species: E. trigona (African milk tree), E. neriifolia (Indian spurge tree), and E. milii (Crown-of-thorns houseplant).
Is eating Euphorbia poisonous?
Recently, I’ve seen a lot of what I believe to be Euphorbia amygdaloides var robbiae, sometimes known as wood spurge, in public areas, however crocus.co.uk claims it is poisonous if consumed and an irritant to the skin and eyes. Any suggestions? Because euphorbia sap makes skin photosensitive, handling it unprotected in the sun might result in blisters. To mention a few, celery, parsley, cow parsley, certain hogweed, and fig sap can also be poisonous. Other plants can irritate the skin; nettles, comfrey, sun or neem, for example, are the most evident.
Euphorbias are ubiquitous, exactly like cow parsley, and you couldn’t possibly pull them out with the best of intentions. The seeds from its berries are extremely deadly (just one can kill a kid), but a recent medication trial discovered that it can be very effective against skin cancer, and it may one day become a new drug. Euphorbias are one of those plants that can be both poison and cure in one.
We had dogs and a garden full of deadly plants where I grew up, but nevertheless we all managed to live. My mother warned us to stay away from certain foods and taught us what foods to eat and avoid, often acting out the dangers of certain plants (it took me years not to be terrified of daturas). It was advised to stay away from milky sap, which is a good general rule.
The outdoors is a wild, perilous, and fascinating place, and I believe it is much preferable to teach kids to respect it than to completely eradicate it.
