Poisonous plants for dogs in India: kaner, sago palm, money plant and 8 more, with what the studies found

Eleven plants grown in Indian homes, gardens and roadsides are poisonous to dogs, including kaner (oleander), peeli kaner, sago palm, money plant (pothos), aloe vera, lantana and arandi (castor). Sago palm is the most studied: 12.3% to 64% of poisoned dogs died in four US case series. Oleander signs start within 2 hours, sago palm liver failure follows in 48 to 72 hours, and castor beans act in 12 to 48 hours. Tulsi and curry leaf are not on the ASPCA list either way.

Key findings

  1. Four US case series of sago palm (cycad) poisoning in dogs found death rates of 12.3%, 32.1%, 50% and 64%.
  2. Merck says signs from oleander and other cardiac glycoside plants are expected within 2 hours and can last 4 to 5 days.
  3. In a 2017 Brazilian study, 0.25 g of fresh oleander leaf per kg made all 10 dogs vomit, within 27 to 75 minutes.
  4. 4 of those 10 dogs developed a slow heartbeat (sinus bradycardia); none died, and all were given supportive treatment.
  5. Sago palm signs can start within 4 hours and progress to liver failure within 48 to 72 hours, per Merck.
  6. Of 98 dogs that ate castor beans (arandi), reported to the US ASPCA from 1987 to 1998, 9% died or were euthanised.
  7. The ASPCA lists money plant (golden pothos), dieffenbachia and aloe vera as toxic to dogs; money tree (Pachira) is non-toxic.
  8. Plants and fungi made up 7.5% of pet exposures reported to the US ASPCA Poison Control in 2025, down from 8.1% in 2024.
  9. Lantana, toxic to dogs per the ASPCA, threatened 303,607 sq km or 44% of Indian forests in a 2020 survey.
  10. We found no Indian case series of plant poisoning in dogs, so every death rate here comes from US, Brazilian or Italian data.

Which plants are poisonous to dogs in India?

At least 11 plants grown in Indian homes, gardens and roadsides are poisonous to dogs. They are kaner, peeli kaner, aak, sago palm, money plant, dumb cane, aloe vera, lantana, arandi, glory lily and dhatura. The ASPCA lists 9 of them as toxic to dogs; Merck lists dhatura, and a 2023 review describes aak's heart toxin.

The ASPCA's dog plant list held 416 toxic entries and 569 non-toxic entries when we counted it on 16 October 2026. Many entries are other names for the same plant, so the true number of species is lower.

The ASPCA does not list aak (Calotropis) or dhatura. Aak contains calotropin, which a 2023 review in Frontiers in Pharmacology calls a highly potent cardenolide, similar in structure to cardiac glycosides such as digoxin. Oleander's heart poisons are cardiac glycosides too. Merck's pet poisoning page lists jimson weed (Datura stramonium) with a weak rapid pulse, dilated pupils, convulsions and coma.

Hindi names follow the Flowers of India botanical database. One trap is the name money plant: in India it means golden pothos, which the ASPCA lists as toxic. The ASPCA's own "Money Tree (Money Plant)" entry is Pachira aquatica, a different plant it lists as non-toxic.

Several kitchen plants also appear here. The ASPCA lists garden mint and lemongrass as toxic to dogs, while basil and coriander (it even gives the name dhania) are non-toxic. See can dogs eat mint and can dogs eat coriander leaves for food amounts.

Is kaner (oleander) poisonous to dogs?

Yes. Kaner (Nerium oleander) contains cardiac glycosides. Merck ranks oleander and foxglove as the most toxic plants in that group, with signs expected within 2 hours and lasting up to 4 to 5 days.

A 2017 Brazilian study gave 10 healthy adult dogs 0.25 g of fresh ground oleander leaf per kg of body weight. That is 2.5 g for a 10 kg dog. All 10 vomited, starting 27 to 75 minutes after dosing, and the authors called it a moderate poisoning.

The heart is the danger. Four of the 10 dogs developed a slow heartbeat, 2 had a second-degree heart block and 1 had a run of ventricular tachycardia. None died, but all 10 were given glucose and supportive treatment, and Merck notes deaths after oleander poisoning even with aggressive treatment.

Peeli kaner (yellow oleander, Cascabela thevetia) carries cardenolides, and the ASPCA lists vomiting, diarrhoea and a slow heart rate. Merck puts it in the same cardiac glycoside group as oleander. We found no published dog case series for it.

Merck says vets treat these plants with repeated doses of activated charcoal, and that digoxin antibody fragments act as specific antidotes to plant cardiac glycosides too. A 2017 US case report used them to save a dog with severe oleander poisoning that had not responded to other heart drugs.

Is sago palm poisonous to dogs?

Yes, and it is the deadliest plant in this report: in four US case series, 12.3% to 64% of dogs with sago palm (cycad) poisoning died. Merck says dogs are extremely sensitive, and that the seeds are the most toxic part although every part is poisonous.

The poison works fast and then slowly. First signs can show within 4 hours. Liver failure can follow within 48 to 72 hours, Merck says, so a dog that seems fine the next morning is not out of danger.

In a 1998 review of 60 dogs in US ASPCA records, 95% developed liver and gut problems and 53.3% had nervous system signs. 38.7% had eaten seeds, and the authors say dogs that eat seeds are likely to get sicker.

Lake et al. 2020Two Texas referral centres13012.3% (16 dogs)Activated charcoal linked to 82% lower odds of death

Why the spread from 12% to 64%? The studies differ in size and in how sick the dogs were on arrival. The largest, 130 dogs in 2020, had the lowest death rate, and 82.3% of its dogs showed signs.

Two studies linked activated charcoal to better survival, though neither was a trial. That is a vet's job, not a home remedy. If your dog chews a sago palm, take it to a clinic the same hour, even if it looks well.

Is money plant poisonous to dogs?

Yes, but it is rarely deadly: money plant (golden pothos, Epipremnum aureum) holds insoluble calcium oxalate crystals that cause instant mouth pain, drooling and vomiting. The ASPCA put devil's ivy (pothos) on its list of the 10 plants it got the most calls about in 2020, saying severe signs are unlikely.

Merck says chewing any part causes immediate intense pain in the mouth. Merck notes that no systemic reaction to insoluble calcium oxalate has been reported; the kidney damage it describes comes from soluble oxalates.

Dumb cane (Dieffenbachia) works the same way, with an extra protein-splitting enzyme. Merck describes death from it as infrequent.

Aloe vera is toxic in the ASPCA list because of saponins and anthraquinones in the leaf, though it calls the gel edible. Merck says eating the leaf latex causes abrupt, severe diarrhoea, low blood sugar or both. Our aloe vera food guide covers the gel question.

Check the exact species before you trust a label. The ASPCA's non-toxic marigold is Calendula, not the Tagetes marigolds used in garlands, and its hibiscus entry is Hibiscus syriacus, not Hibiscus rosa-sinensis. Neither Tagetes nor Hibiscus rosa-sinensis appears on the dog list.

Are lantana, arandi (castor) and dhatura poisonous to dogs?

All three are poisonous. In US ASPCA records, 9% of 98 dogs that ate castor beans died or were put down between 1987 and 1998. The ASPCA warns that as little as one ounce (about 28 g) of seeds can be lethal.

Castor signs typically start 12 to 48 hours after eating, the ASPCA says, so a quiet first evening means little. Whether the beans were chewed or swallowed whole may change how sick a dog gets, the 2000 study found.

Lantana (raimuniya) is widespread in India. A 2020 survey of 207,100 sq km of Indian forest found it in 154,837 sq km of the area surveyed. It estimated lantana threatened 303,607 sq km, or 44% of India's forests.

The ASPCA lists lantana's toxins as pentacyclic triterpenoids and its signs as vomiting, diarrhoea, laboured breathing and weakness. It notes liver failure is more common in livestock. Its list of the most-called plants of 2020 said lantana causes liver failure in dogs and cats only in rare cases.

Glory lily (Gloriosa superba) holds colchicine-related alkaloids. The ASPCA lists bloody vomiting and diarrhoea, shock, kidney failure, liver damage and bone marrow suppression.

Dhatura is a roadside weed across India. Merck lists jimson weed, Datura stramonium, with the whole plant toxic and seeds in particular. The only dog case we found in PubMed is a single 2002 report from Brazil, so there is no dog death rate to give.

How common is plant poisoning in dogs?

Plants and fungi made up 7.5% of pet poison exposures reported to the US ASPCA Poison Control in 2025, sixth among its top 10 categories. The share was 8.1% in 2024.

Over-the-counter medicines (16.9%) and human food and drink (16.4%) both came well ahead. Chocolate alone was 13.6%. For Indian kitchen risks, see our most toxic foods for dogs report.

Italy's Milan poison centre gives a European view. From 2000 to 2011, plants made up 5.7% of its 2,150 animal inquiries, and dogs were 61.8% of the plant calls. Sago palm and oleander were among the plants most often involved.

India has no published equivalent. We found no Indian animal poison centre data and no Indian case series of plant poisoning in dogs. Nobody can yet say how often kaner or sago palm sickens dogs here.

For what studies say about dogs that graze on plants, see our report on why dogs eat grass.

What should I do if my dog eats a poisonous plant?

Call a vet straight away and take a piece of the plant. Two US sago palm studies linked activated charcoal from a vet to survival, and in Lake's 2020 study dogs given it had 82% lower odds of death.

Do not wait for signs. Castor can take 12 to 48 hours to show, and sago palm liver damage 48 to 72 hours. Merck advises daily liver tests for 72 hours after sago palm exposure.

Photograph the plant and note the time. Kaner and peeli kaner share a Hindi name, so tell the vet the flower colour or show the photo.

Sago palm, kaner, peeli kaner, arandi seeds and glory lily are emergencies even if your dog seems fine. Money plant and dumb cane usually cause mouth pain and drooling, and Merck calls death from dumb cane infrequent, but still call your vet.
  • Remove plant bits from the mouth and keep a sample or photo.
  • Note when your dog ate it and roughly how much.
  • Call your vet or nearest animal hospital before driving over.
  • Do not try home remedies to make your dog vomit unless a vet tells you to.
  • Keep sago palm seeds, castor seeds and oleander clippings out of reach.

Vets are not evenly spread across India. Our report on vets per lakh population shows the gaps. The 1962 animal ambulance is built for livestock, so find a small animal clinic before you need one.

Fallen leaves and clippings matter too. Oleander is toxic fresh or dry, Merck says, so keep pruned branches and fallen leaves out of reach. Our monsoon dog care guide covers wet season walk routines.

Are tulsi and curry leaf plants safe for dogs?

Neither tulsi (Ocimum tenuiflorum) nor curry leaf appears on the ASPCA dog plant list, as toxic or non-toxic, when we checked on 16 October 2026. Its close relative sweet basil (Ocimum basilicum) is listed as non-toxic.

So the evidence is a gap, not a clean bill of health. Small amounts as food are a different question from a dog chewing a whole plant. See our food guides on tulsi, curry leaves and basil.

Frequently asked questions

Which plants are poisonous to dogs in India?

Common ones are kaner (oleander), peeli kaner, sago palm, money plant (pothos), dumb cane, aloe vera, lantana, arandi (castor), glory lily, aak and dhatura. The ASPCA lists 9 of these 11 as toxic to dogs.

Is kaner poisonous to dogs?

Yes. Oleander contains cardiac glycosides. Merck expects signs within 2 hours, and in a 2017 Brazilian study 0.25 g of leaf per kg made all 10 dogs vomit and 4 develop a slow heartbeat.

Is sago palm poisonous to dogs?

Yes. In four US studies, 12.3% to 64% of poisoned dogs died. Signs can start within 4 hours and liver failure can follow in 48 to 72 hours.

Is money plant poisonous to dogs?

Yes. Golden pothos, called money plant in India, has insoluble calcium oxalates that cause mouth pain, drooling and vomiting. It is rarely fatal, and the ASPCA listed it among the 10 plants it got the most calls about in 2020.

Is aloe vera poisonous to dogs?

The ASPCA lists aloe as toxic, causing vomiting, lethargy and diarrhoea, but calls the gel edible. Merck says the leaf latex can cause severe diarrhoea, low blood sugar or both.

Is lantana poisonous to dogs?

Yes. The ASPCA lists vomiting, diarrhoea, laboured breathing and weakness. Liver failure is more common in livestock. A 2020 study found lantana threatens 44% of India's forest area.

How long does plant poisoning take to show in dogs?

It depends on the plant. Money plant hurts at once, oleander within 2 hours, sago palm within 4 hours, and castor beans after 12 to 48 hours.

Is tulsi safe for dogs?

Tulsi is not on the ASPCA dog plant list either way. Its relative sweet basil is listed as non-toxic. Treat it as unstudied and stop a dog from chewing whole plants.

What should I do if my dog eats sago palm?

Go to a vet at once, even if your dog looks fine. In a 2020 US study of 130 dogs, those given activated charcoal by vets had 82% lower odds of death.

Methodology and limitations

Toxic or non-toxic ratings, toxic principles and clinical signs come from the ASPCA Toxic and Non-Toxic Plant List and its individual plant pages, read on 16 October 2026. We counted the 416 toxic and 569 non-toxic entries on the dog list page that day; entries include alternative names, so they overstate the number of species.

Onset times, treatment notes and toxin descriptions come from two Merck Veterinary Manual chapters. They are Houseplants and Ornamentals Toxic to Animals (Schmid, full review November 2023) and Plants Poisonous to Animals (Brownie, last updated May 2026).

Death rates come from the abstracts of peer-reviewed case series: Albretsen et al. 1998 and 2000, Ferguson et al. 2011, Clarke and Burney 2017, Lake et al. 2020, Caloni et al. 2013 and Bertero et al. 2021. Oleander signs come from the full text of Camplesi et al. 2017.

Hindi names come from the Flowers of India database (flowersofindia.net), which cites Names of Plants in India. Lantana spread comes from Mungi, Qureshi and Jhala (2020), Global Ecology and Conservation 23.

Grams per dog (2.5 g for a 10 kg dog) and ounces to grams (1 ounce is about 28 g) are our own arithmetic. Bars for ranges show the upper end; labels show the full range.

Limitations. We found no Indian case series, poison centre data or hospital audit on plant poisoning in dogs. Every death rate and onset time here comes from studies in the US, Brazil or Italy. Those studies are small and mostly retrospective, and several come from referral hospitals that see sicker dogs. Links between treatment and survival in them are associations, not proof of cause. Death rates for the same plant differ widely between studies. The Milan figures cover all animal species. Aak, tulsi, curry leaf and dhatura have no ASPCA rating, and we found no dog studies for peeli kaner, aak, glory lily or lantana. Nothing here is a diagnosis; call your vet if your dog eats any plant you are unsure of.
