Narcissus pseudonarcissus
Toxic🐾Gelbe Narzisse · (Narcissus pseudonarcissus)
Amaryllis family (Amaryllidaceae)
Description
The bulb of the wild daffodil yields galantamine, a compound used as an approved medication for Alzheimer's dementia — a notable fact given that the whole plant is otherwise among the most toxic native spring bloomers. Flower and bulb appear in March and April and contain, besides galantamine, mainly the alkaloid lycorine along with narciclasine, homolycorine and needle-shaped calcium oxalate crystals. In folk medicine the bulb was applied externally as a wound dressing; modern use is limited to standardised, medically controlled extracts. The raw plant is toxic — the bulb in particular is repeatedly mistaken for kitchen onions, leading to poisonings with nausea, severe vomiting, diarrhoea and circulatory symptoms. Skin contact with the sap can trigger so-called daffodil rash, an irritant contact dermatitis, in sensitive individuals. The vase water of cut flowers is also phytotoxic to other flowers sharing the same vase.
🌿 Risk of confusion — read before wild-harvesting!
Poisonings classically occur through accidental confusion of the bulb with kitchen onion or shallot — a documented problem particularly during food shortages (Dutch Hunger Winter 1944/45; recently: migrant poisonings in Central Europe).
External use only!
This plant must NOT be taken internally. Use only as compress, salve, or bath.
CONTRAINDICATED during pregnancy
Lycorine and other Amaryllidaceae alkaloids are embryotoxic in vitro and teratogenic in animal studies; lycorine inhibits protein biosynthesis at the ribosomal level and impacts cell division. Any oral or high-dose topical application of narcissus material during pregnancy is contraindicated. Pharmaceutically isolated galantamine (Alzheimer's indication) has its own risk assessment — administration to pregnant women only on strict medical indication.
CONTRAINDICATED during breastfeeding
Transfer behaviour of Amaryllidaceae alkaloids into breast milk is insufficiently studied; given the acute toxicity (vomiting, seizures) strictly contraindicated for the infant. Pharmaceutical galantamine: breastfeeding is not recommended per the product information.
CONTRAINDICATED for children
Children frequently poison themselves by eating bulbs (confusion) or flowers and leaves in family gardens — even a single bulb can trigger severe vomiting and dehydration in a small child. Narcissi in kindergartens, schoolyards and near playgrounds should be out of reach or preferably replaced with non-toxic spring bloomers. No lay use in children.
Critical drug interactions with:
Cholinesterase-Hemmer (Donepezil, Rivastigmin, Galantamin selbst, Pyridostigmin)
Traditional external use in the Mediterranean and Arab world: cut-open fresh narcissus bulbs were applied as poultices for ulcers, abscesses, poorly healing wounds and 'corns' (callous skin lesions). Avicenna (Ibn Sina, 11th century) mentions Narcissus in his Canon of Medicine. Mechanism: local irritant and macerating action of the alkaloids (lycorine, homolycorine, narcissin). Today obsolete due to contact dermatitis risk ('daffodil rash') and systemic absorption.
Preparation & dosage
Occupational contact dermatitis ('daffodil itch', 'lily rash') in florists, gardeners and bulb sorters — not a therapeutic application but a relevant occupational medicine and allergology issue. The plant sap contains calcium oxalate raphides and alkaloids (lycorine, narciclasine) that mechanically and chemically trigger an irritant and allergic contact dermatitis. Clinically documented since the late 19th century; particularly affects hands and forearms. Protective gloves are the standard prevention.
Preparation & dosage
Symbolic and cultural-historical significance: the wild daffodil is the national flower of Wales (worn on St. David's Day, 1 March) and is regarded in Christianity as the 'Lent lily' / 'Easter bell' because of its bloom during Lent. In Greek mythology the plant is linked to the youth Narcissus, who fell in love with his own reflection — root of the term 'narcissism'. The Marie Curie Cancer Care Foundation has used the daffodil as the symbol of UK hospice work since 1986. No medicinal use — purely cultural-historical and symbolic significance.
Preparation & dosage
Historical documentation only — do NOT use
These internal applications are historically documented. This plant is highly toxic — self-treatment can cause severe poisoning or death. For documentation only, explicitly NOT a recommendation.
Historical folk-medicinal use of dried and powdered bulb as an emetic and as a wound dressing for burns and boils. The application is based on the strong emetic effect of the main alkaloid lycorine and the locally skin-irritating action of further Amaryllidaceae alkaloids. Already Dioscorides (1st century CE) and Pliny describe Narcissus applications — today completely obsolete due to unpredictable toxicity (LD50 lycorine oral mouse ca. 41 mg/kg). No modern recommendation for use.
Preparation & dosage
Galantamine — an Amaryllidaceae alkaloid originally extracted commercially from Galanthus species and the Narcissus pseudonarcissus cultivar 'Carlton' — is today an approved prescription medicine (Reminyl®, Razadyne®) for mild to moderate Alzheimer's dementia (selective acetylcholinesterase inhibitor and allosteric modulator of nicotinic receptors). Welsh fields ('Black Mountains' daffodil farms) supplied part of the global galantamine demand in the 2000s. Important: this application concerns standardised, isolated galantamine — no direct use of raw narcissus material. Relevance as a constituent, not as a folk application of the plant.
Preparation & dosage
Homeopathic use of Narcissus pseudonarcissus (D6–D12) for catarrhal respiratory complaints, bronchitis in children and irritable cough — based on the homeopathic similarity principle to the symptoms of narcissus poisoning (mucosal irritation, cough, vomiting). From D6/D12 onward, pharmacologically active alkaloid amounts are no longer present; clinical efficacy over placebo not established. Low potencies below D6 are prescription-only in Germany.
Preparation & dosage
⚠ External use only
TOXIC — ALL PLANT PARTS, ESPECIALLY THE BULB. Narcissus pseudonarcissus contains Amaryllidaceae alkaloids (lycorine as main component, alongside galantamine, homolycorine, narciclasine, narcissine) plus calcium oxalate raphides. Poisonings classically occur through accidental confusion of the bulb with kitchen onion or shallot — a documented problem particularly during food shortages (Dutch Hunger Winter 1944/45; recently: migrant poisonings in Central Europe). Symptoms (oral): within 15–60 minutes nausea, severe vomiting, diarrhoea, abdominal pain, salivation, sweating, dizziness; with higher amounts tachycardia, hypotension, seizures. Dermal: 'daffodil rash' / 'lily rash' / florist's eczema — irritant and allergic contact dermatitis from plant sap and calcium oxalate raphides. Cut-flower sap is phytotoxic and damages other cut flowers in the same vase (24 h separate watering recommended). On suspected oral poisoning: poison control (regional centres), abundant water, NO salt water for induced vomiting; for children and pets present immediately to medical/veterinary care. ASPCA classification (accessed 2026-08-10): toxic to dogs and cats. The ASPCA classifies the whole genus this way.

Drug interactions
Cholinesterase-Hemmer (Donepezil, Rivastigmin, Galantamin selbst, Pyridostigmin)
Galantamine contained in Narcissus pseudonarcissus is itself an acetylcholinesterase inhibitor; oral intake of crude extracts in addition to standardised galantamine or other cholinesterase inhibitors leads to additive cholinergic effects (bradycardia, bronchospasm, seizures, cholinergic crisis). Clinically relevant only in plant material poisoning, but theoretically mandatory to consider.
Anticholinergika (Atropin, Scopolamin, Trizyklische Antidepressiva, Antihistaminika 1. Generation)
Anticholinergics antagonise the cholinergic transmission enhanced by galantamine and lycorine — in poisoning with narcissus crude material, atropine is deliberately used in emergency medicine as antidote (analogous to the therapy of cholinesterase inhibitor poisoning).
Betablocker (Metoprolol, Bisoprolol, Atenolol)
Galantamine enhances vagally mediated bradycardia; combination with beta-blockers may trigger symptomatic bradycardia, AV block and syncope. Relevant in clinical use of pharmaceutical galantamine; with plant material exposure an additional risk factor.
Anästhetika vom Succinylcholin-Typ (depolarisierende Muskelrelaxanzien)
Galantamine (in the plant and as a medicine) prolongs neuromuscular blockade by succinylcholine via acetylcholinesterase inhibition. Document galantamine intake before planned surgery; with narcissus material poisoning anaesthesia only under experienced supervision.
Contraindications
- Any form of oral self-administration of narcissus material — no safe home dose possible
- Known Amaryllidaceae allergy or known florist's dermatitis — sensitisation worsens with repeated contact
- Pregnancy, breastfeeding, children and adolescents (see above)
- Households with cats, dogs and rodents — narcissus bulbs are markedly toxic for pets (vomiting, seizures, cardiac arrhythmias)
- Pharmaceutical galantamine specifically contraindicated in severe hepatic or renal impairment, severe bradycardia and active gastric ulcer (see Reminyl®/Razadyne® product information)
Harvested part: bulb and flower
- Time of day:
- Late morning in dry weather after the foliage has died down (June–August); for pharmaceutical galantamine production, the cultivar 'Carlton' is grown and the bulb is harvested after 2–3 years of growth. PROTECTIVE GLOVES MANDATORY — lycorine and calcium oxalate raphides reliably trigger florist's dermatitis.
- Drying:
- After harvest, brush soil from the bulbs and dry in a dark, airy place at 15–20 °C (propagation material). For pharmaceutical galantamine extraction, fresh bulbs are crushed and extracted immediately (ethanol, acidic aqueous). Store raw bulbs separately from kitchen onions, garlic and food — confusion risk! Clear labelling, out of reach of children and pets.
- Storage:
- Dry, cool (8–15 °C), dark, out of reach of children and pets; label containers clearly as 'narcissus bulb — toxic'; NEVER store in kitchen cabinets or among kitchen onions.
- Time of day:
- Early morning hours at full bloom; place cut flowers separately in water for 12–24 h ('conditioning') before combining with other cut flowers — the plant sap otherwise damages other flowers in the same vase.
- Drying:
- Fresh flowers can be dried only to a limited extent (loss of shape and colour); culturally and medicinally, fresh flowers are mainly used as cut flowers or as symbolic flowers. Wear protective gloves when cutting, as the cut sap is skin-irritating.
- LycorineAlkaloidContent: 0.1-0.5 % in der Zwiebel (variabel nach Sorte und Erntezeit)use.plant_part.bulb
Lead alkaloid of the Amaryllidaceae and main contributor to the toxicity of Narcissus pseudonarcissus. Pyrrolophenanthridine skeleton; inhibits ribosomal protein biosynthesis (peptidyl transferase activity) and thereby triggers severe vomiting, seizures and cell division disorders. LD50 oral mouse ca. 41 mg/kg. Lycorine is also the marker for forensic identification of narcissus poisoning.
- GalantamineAlkaloidContent: 0.05-0.2 % in der Zwiebel (Sorte 'Carlton' deutlich höher — bis 0.4 %)use.plant_part.bulb
Selective, competitive acetylcholinesterase inhibitor and positive allosteric modulator of nicotinic acetylcholine receptors. Pharmaceutically standardised (Reminyl®, Razadyne®) approved for mild to moderate Alzheimer's dementia. Welsh cultivar farming ('Black Mountains', Wales) delivered a substantial part of the global galantamine raw material; today increasingly replaced by total synthesis. Biosynthetic precursor: narwedine.
- NarciclasineAlkaloidContent: Spuren bis 0.05 % in der Zwiebeluse.plant_part.bulb
Isocarbostyril alkaloid with marked antiproliferative effect; in vitro cytotoxic against various tumour cell lines (apoptosis induction via eIF4E and Rho GTPase modulation). Co-responsible for the cell-toxic action of the plant sap on other cut flowers and for the skin-irritant potential.
- HomolycorineAlkaloidContent: Spuren bis 0.05 % in der Zwiebeluse.plant_part.bulb
Accompanying alkaloid with a pharmacological profile similar to lycorine (emetic action, inhibition of protein biosynthesis) but lower toxicity. Used as a chemotaxonomic marker within the genus Narcissus.
- Narcissine (Pseudolycorine)AlkaloidContent: Spurenuse.plant_part.bulb
Historically eponymous alkaloid (occasionally used synonymously with lycorine); structurally and pharmacologically closely related to lycorine. In older sources, the entire alkaloid mixture of the narcissus bulb is referred to as 'narcissine'.
- Calciumoxalat-RaphidenOtherContent: deutlich nachweisbar in Zwiebel und Saftuse.plant_part.bulb
Needle-shaped calcium oxalate crystals in specialised idioblasts; mechanically irritant to skin and mucous membranes. Main contributor to the mechanical component of florist's dermatitis and to oral mucosal irritation in accidental ingestion.
- PretazettineAlkaloidContent: Spurenuse.plant_part.bulb
Amaryllidaceae alkaloid with documented antiviral activity in vitro (RSV, HSV); present in N. pseudonarcissus in low amounts. No practical therapeutic use — relevance primarily as a phytochemical marker and in pharmacological research.
- Flavonoide (Kaempferol-, Quercetin-Glykoside)FlavonoidContent: nicht quantifiziert (Blüten, Blätter)Flower
Antioxidant accompanying substances in flowers and leaves; contribute to the yellow flower colour (together with carotenoids). No primary role in toxicology; minor pharmacological action of their own.
