Is the Snowdrop Poisonous? – Toxicity to Humans, Dogs, and Cats

Plants Reviewed 2026-04-27 By Hannah Reeve · Researched and fact-checked against ASPCA and poison-control sources

Yes. All parts of the snowdrop plant are toxic, and the bulbs carry the highest concentration of poison. The plant contains galantamine, an alkaloid that affects the nervous system and can cause serious symptoms in both people and pets. Ingestion is the risk. Touching the plant and sniffing the flowers are safe.

Identifying a Snowdrop

Snowdrops (genus Galanthus) are small perennial bulb flowers that typically appear in late winter and early spring. You can recognize them by these features:

White, bell-shaped flowers that hang downward from slender stems
Narrow gray-green leaves that emerge from the base
Small bulbs. The bulb is the most toxic part of the plant
Flowers grow singly on each stem, not in clusters

They are commonly confused with winter Aconite (which has yellow flowers) and early daffodils (which are larger and also yellow). Snowdrops are notably smaller and more delicate than either.

The plant is native to Europe and parts of the Middle East but has naturalized widely across Europe and North America. You will find them in gardens, parks, and woodland areas. They are popular ornamental plants, especially in informal and naturalized plantings.

What Makes Snowdrops Toxic

The primary toxin in snowdrops is galantamine. This alkaloid is an acetylcholinesterase inhibitor, which means it blocks an enzyme that breaks down the neurotransmitter acetylcholine. The result is overstimulation of the parasympathetic nervous system, which slows heart rate and disrupts nerve signaling.

Snowdrops also contain other alkaloids and glycosides, including scillaine and lycorine, which contribute to gastrointestinal toxicity.

Galantamine concentration is highest in the bulb. Stems and leaves contain lower levels. Flowers are mildly toxic but less dangerous than the bulb.

Here is the irony worth knowing: galantamine is used medically to treat Alzheimer’s disease and vascular dementia. It is isolated from snowdrops and other plants in the Galanthus genus and prescribed in controlled, purified tablet form under the name Reminyl or as a generic. The same compound that can poison you in uncontrolled doses is therapeutic at precise doses. Do not let this imply the plant is safe. It is not.

Is It Dangerous to Humans?

Yes. Snowdrops are poisonous to humans.

Bulb ingestion causes the most severe symptoms. Approximately three or more bulbs is the threshold where symptoms typically appear, according to data from the Bonn Poison Center. Flowers and leaves are less toxic but can still cause gastrointestinal upset.

Symptoms in humans include dizziness, nausea, vomiting, diarrhea, abdominal pain, and excessive drooling. Severe cases can involve muscle spasms, paralysis, and cardiac effects.

Is It Dangerous to Dogs and Cats?

Both dogs and cats face the same risk. Snowdrops are toxic to both species.

Dogs are the more likely offenders. They dig. They chew. A dog that unearths a snowdrop bulb and eats it is going to have a bad time. Cats are typically affected through ingestion of leaves or flowers, though bulb eating causes the most severe response.

Symptoms in dogs and cats:

Drooling
Vomiting
Diarrhea
Abdominal pain
Incoordination (stumbling, falling)
Drop in blood pressure and heart rate
Muscle spasms
Seizures in severe cases

Prognosis is generally good with prompt veterinary care. Deaths are rare when treatment is sought quickly.

What to Do If Someone Ingests a Snowdrop

First: do not induce vomiting unless a medical professional tells you to. Second: contact the appropriate resource immediately.

For humans, call your local poison control center. In the US, that number is 1-800-222-1222. The Bonn Poison Center recommends drinking fluids if a small amount was ingested, but follow the poison control operator’s specific instructions. Bring any remaining plant material to help with identification.

For dogs or cats, call your veterinarian or the Pet Poison Helpline (855-764-7661). Bring a sample of the plant if you can safely collect it.

Seek emergency care if the person or animal shows severe symptoms: seizures, collapse, difficulty breathing, or loss of consciousness.

There is no specific antidote for snowdrop poisoning. Treatment is supportive: IV fluids, induced vomiting, activated charcoal to limit absorption. These are decisions for a vet or a doctor to make.

FAQ

Are snowdrops poisonous to touch? No. Skin contact with the plant causes no known toxicity. Ingestion is the risk, not skin contact. Wash your hands after handling if you are concerned.

Can snowdrops kill a dog or cat? Fatal cases are extremely rare with prompt veterinary treatment. Serious symptoms are possible, especially from bulb ingestion. Seek vet care immediately if your pet has eaten any part of a snowdrop.

Are snowdrops more poisonous than daffodils? No. Daffodil bulbs are considered significantly more toxic. Snowdrop toxicity is generally mild to moderate. That said, do not let this make you casual about it.

Can I have snowdrops in my garden if I have pets? Yes, but place bulbs out of reach. Digging dogs are the main risk. Consider raised beds, pot planting, or placing chicken wire over bulb beds during planting season.

What do snowdrop bulbs look like? Small, white, and pointed at the top. They resemble miniature onion bulbs. This is not coincidence. They are sometimes confused with edible spring onions, which is one reason accidental ingestions happen.

Can you eat snowdrops? No. All parts of the plant are toxic to humans. Do not eat any part of a snowdrop under any circumstances.

What is the treatment for snowdrop poisoning? No specific antidote exists. Supportive care from a medical professional: IV fluids, possibly induced vomiting, activated charcoal to reduce absorption. A vet or doctor will determine the right approach based on how much was eaten and when.

Do snowdrops have any medicinal use? The alkaloid galantamine, isolated from snowdrops and related plants, is used to treat Alzheimer’s disease and vascular dementia. This is a purified pharmaceutical product, not the raw plant. The whole plant is dangerous and should never be used as a home remedy.
