TryptamineMorning glory
Morning glory (Ipomoea tricolor Cav., Convolvulaceae) is an annual climbing vine whose seeds contain psychoactive ergoline alkaloids. Its principal active compound, LSA (ergine), is structurally related to LSD. Ergine activates serotonin pathways in the brain,[1] producing altered perception and cognition.
Morning glory (Ipomoea tricolor Cav., Convolvulaceae) is an annual vine whose seeds contain ergoline alkaloids produced by a heritable fungal endosymbiont, Periglandula clandestina.[1] Its principal psychoactive constituent, LSA (ergine), is a semirigid ergoline structurally related to LSD. Ergine produces its primary effects through presumed partial agonism at 5-HT₂A serotonin receptors, generating altered perception and cognition.[2]

TryptamineIndigenous peoples of Mesoamerica used a closely related plant, Turbina corymbosa, in ritual divination and healing for centuries.[2] Albert Hofmann identified ergine in morning glory seeds in 1960 — a discovery initially dismissed as laboratory contamination before independent confirmation.[3] Seeds remain legal in most countries today, while the isolated alkaloid is controlled in several jurisdictions.
Subjective effects include visual distortions, altered thinking, sedation, lethargy, and introspective thought. The experience is shorter and less visually intense than LSD, defined as much by physical discomfort as by perceptual change.[4] Nausea is nearly universal; alkaloid content varies so widely between batches that some commercial seed lots contain no active compounds at all.[5]
Dependence liability is presumed low based on the ergoline class,[6] but documented adverse events include cardiovascular disruption, psychosis-like states, and suicidal ideation.[7][8] Commercially sold ornamental seeds are often pesticide-coated, adding toxic risk unrelated to the alkaloids.[9] No controlled clinical trials, pharmacokinetic data, or formal dose studies exist for any morning glory preparation.
History[edit]
Traditional and historical use
The closely related Turbina corymbosa — ololiuqui in Nahuatl — was used by Aztec, Mazatec, Zapotec, and other Mesoamerican peoples for divination and healing.[2] I. tricolor was also used in some of these traditions under the Nahuatl name "tlitlitzin".[2] Spanish colonial authorities documented and suppressed these practices from the 17th century onward.
Western discovery and research
Richard Evans Schultes began field documentation of ololiuqui in the 1930s–1940s.[10] Albert Hofmann identified ergine in morning glory seeds at Sandoz Laboratories in 1960 — his results were initially dismissed as LSD contamination before independent researchers confirmed them.[3][11] Ergine was scheduled as a controlled substance in the United States in 1970.
Modern era
Recreational use of morning glory seeds as a legal LSD substitute emerged in the 1960s, then subsided. A resurgence occurred in Poland and elsewhere in the 2010s, with web-report analyses confirming symptoms consistent with earlier medical case reports.[4] In 2025, the specific I. tricolor fungal symbiont was formally named Periglandula clandestina sp. nov..[12]
Botanical Overview[edit]
Taxonomy and family
Ipomoea tricolor Cav. belongs to the family Convolvulaceae — the bindweed or morning glory family. The genus Ipomoea comprises 600–700 species distributed across tropical and subtropical regions.[13] In the context of psychoactive use, "morning glory" refers principally to I. tricolor and its named cultivars, including 'Heavenly Blue', 'Flying Saucers', and 'Pearly Gates'.
Native range and habitat
I. tricolor is native to tropical regions of the Americas and is now cultivated worldwide as an ornamental garden plant. It thrives in warm, well-drained soil with full sun and is commercially available as garden seed in most temperate and tropical countries.
Identification
I. tricolor is a fast-growing annual vine with heart-shaped leaves and funnel-shaped flowers — typically 6–8 cm across — that open in the morning. The 'Heavenly Blue' cultivar produces vivid sky-blue flowers with a white throat. Seeds are small, dark brown to black, and hard-coated; they are the sole documented psychoactive part of the plant. Their alkaloid content is produced not by the plant itself but by Periglandula clandestina, a heritable fungal symbiont.[12]
Alkaloid Profile[edit]
Dominant alkaloid
LSA (ergine, d-lysergic acid amide) is the principal psychoactive alkaloid in I. tricolor seeds. It is structurally related to LSD and is presumed to activate serotonin pathways in the brain — inferred from structural analogy rather than direct binding studies.[1] No published receptor binding data for ergine exist in peer-reviewed literature.
Minor alkaloids
Morning glory seeds also contain isoergine (d-isolysergic acid amide), a less psychoactive isomer of ergine, and ergonovine (ergometrine), a potent blood vessel constrictor and uterine contractor.[11] These alkaloids are not made by the plant itself but by Periglandula clandestina, a heritable fungal symbiont residing within the plant's tissues.[12] The relative proportions vary by cultivar and growing conditions; no controlled study has determined how the alkaloid mix shapes the subjective experience.
Variability
Alkaloid content varies substantially across cultivars, growing conditions, and commercial sources. In one analytical study, 2 of 5 commercial lots contained zero detectable ergot alkaloids.[5] Seed count is not a reliable dose proxy — potency differences likely reflect variation in the density and viability of the fungal symbiont across different seed lineages.
Neuroscience[edit]
Where it acts
Ergine is presumed to produce its effects primarily by partially activating serotonin receptors in the brain — the same core mechanism as LSD and psilocybin.[1][6] Additional activity at other receptor systems — including dopamine and adrenergic pathways — contributes to the pronounced sedation and body load that distinguish morning glory from LSD.[14]
What it changes
Tolerance builds rapidly — within 3–4 days of repeated use — through the same serotonin downregulation seen with LSD and psilocybin, with cross-tolerance expected across all three.[1] Individuals whose bodies metabolize the alkaloid slowly may experience longer, more intense effects at any given dose.[15]
No neuroimaging studies of morning glory seeds or pure ergine have been published. Human pharmacokinetic data for ergine remain uncharacterized — available blood concentration figures come only from forensic cases involving Argyreia nervosa seeds.[8] Whether the mix of ergine, isoergine, and ergonovine in crude seed extract shapes the qualitative character of the experience is unknown.
Subjective Effects[edit]
Morning glory seeds produce a sedation-heavy psychedelic state. Visual distortions and introspective thought occur, but the experience is defined as much by its physical character — lethargy, nausea, and a heavy body sensation — as by its perceptual effects.[4] The preparation method and batch alkaloid variability are the two largest sources of unpredictability.
Compared to LSD, the experience is shorter and less visually elaborate. Compared to psilocybin mushrooms, the perceptual overlap is moderate, but morning glory's gastrointestinal and vasoconstrictive load is more pronounced and less predictable. Cold water extraction reduces nausea for some users, but no controlled comparison confirms a meaningful difference in perceptual character between preparations.
Mesoamerican ritual use of the closely related Turbina corymbosa (ololiuqui) was documented by Spanish colonial naturalists in the 16th century.[3] Albert Hofmann identified ergine in morning glory seeds in 1960, a finding initially met with accusations of sample contamination before independent confirmation.[4] Ergine is classified as Schedule III in the United States while the seeds themselves remain legal in most jurisdictions.
Subjective effects include visual distortions, altered cognition, sedation, and introspective thought. The experience is shorter and less visually intense than LSD, dominated by pronounced body load and lethargy.[5] Nausea is a near-universal unsought effect, and alkaloid content varies substantially between seed batches — some commercial lots contain no detectable ergot alkaloids.[6]
Dependence liability is unstudied but presumed low based on ergoline class data.[7] Documented adverse events include cardiovascular dysregulation, psychosis-like states, and suicidal ideation,[8][9] compounded by the hepatotoxic and neurotoxic risk of pesticide coatings on commercially sold ornamental seeds.[10] No controlled clinical trials, human pharmacokinetic data, or formal dose-finding studies exist for any morning glory preparation.
History[edit]
Traditional and historical use
The closely related Turbina corymbosa — known as ololiuqui ("round thing" in Nahuatl) — was used in Mesoamerican ritual contexts by Aztec, Mazatec, Zapotec, and other indigenous groups for divination and healing ceremonies.[3] Spanish colonial authorities documented and suppressed these practices from the 17th century onward. I. tricolor was used alongside or interchangeably with T. corymbosa in some indigenous contexts under the Nahuatl name "tlitlitzin".[3]
Western discovery and research
Richard Evans Schultes began field documentation of ololiuqui in the 1930s–1940s.[11] In 1960, Albert Hofmann at Sandoz Laboratories isolated ergine and related ergot compounds from Rivea corymbosa seeds — a finding that initially provoked accusations of LSD contamination before independent researchers confirmed the results.[4][12]
Modern era
Recreational use of morning glory seeds as a "legal LSD substitute" appeared in the United States during the 1960s, then subsided. A resurgence occurred in Poland and elsewhere in the 2010s, with systematic web-report analysis confirming symptoms consistent with earlier medical case reports.[5]
In 2011, the fungal genus Periglandula was described as the true biological source of ergot alkaloids in Convolvulaceae.[12] In 2025, the specific I. tricolor symbiont was named Periglandula clandestina sp. nov..[1]
Ergine was listed as Schedule III under the United States Controlled Substances Act in 1970. Louisiana restricted morning glory seed consumption in 2005, and Italy classified morning glory seeds as controlled narcotic drugs in the early 2010s.[13]
Botanical Overview[edit]
Taxonomy and family
Ipomoea tricolor Cav. belongs to the family Convolvulaceae (the bindweed or morning glory family). The genus Ipomoea comprises 600–700 species distributed primarily across tropical and subtropical regions.[14] The common name "morning glory" is applied broadly across the genus; in the context of psychoactive use, it refers principally to I. tricolor and its named cultivars, including 'Heavenly Blue', 'Flying Saucers', and 'Pearly Gates'.
Native range and habitat
I. tricolor is native to tropical regions of the Americas and is now cultivated worldwide as an ornamental garden plant. It grows readily in warm, well-drained soils with full sun exposure and is commercially available as garden seed stock in most temperate and tropical countries.
Identification
I. tricolor is a fast-growing annual vine that can reach several meters in length. Leaves are heart-shaped with smooth margins. Flowers are funnel-shaped, typically 6–8 cm in diameter, and open in the morning — the trait that gives the plant its common name. The 'Heavenly Blue' cultivar produces vivid sky-blue flowers with a white throat; other cultivars display purple, white, or multicolored blooms. Seeds are small, dark brown to black, wedge-shaped, and hard-coated.
Harvesting
Seeds are the sole documented psychoactive part of the plant. They are harvested from mature seed pods after the flowers have dried and died back. The ergoline alkaloids responsible for psychoactive effects are not synthesized by the plant itself but by Periglandula clandestina, a heritable fungal endosymbiont residing within the plant's tissues.[1]
Alkaloid Profile[edit]
Dominant alkaloid
LSA (ergine, d-lysergic acid amide) is the principal psychoactive alkaloid in I. tricolor seeds. Ergine is a semirigid ergoline structurally related to LSD, and its psychoactive mechanism is presumed to be partial agonism at 5-HT₂A serotonin receptors — inferred from structural analogy rather than published binding affinity data.[2] No published binding affinity values for ergine at individual receptor subtypes exist in peer-reviewed literature.
Minor alkaloids
Morning glory seeds contain several additional ergoline alkaloids alongside ergine. Isoergine (d-isolysergic acid amide) is the C-8 epimer of ergine and is generally considered less psychoactive. Ergonovine (ergometrine) is a documented uterotonic agent with potent vasoconstrictor activity.[12] The relative proportions of these alkaloids vary across cultivars and growing conditions, and no controlled comparison of isolated ergine versus crude seed extract has been conducted to determine how the alkaloid mixture modulates the subjective experience.
Variability
Alkaloid content varies substantially between seed batches, cultivars, and commercial sources. In one analytical study, 2 of 5 commercial lots tested contained zero detectable ergot alkaloids.[6] This variability makes dose prediction from seed count unreliable. Potency differences likely reflect variation in the density and viability of the Periglandula endosymbiont across growing conditions and seed lineages.
Biosynthesis
The ergoline alkaloids in I. tricolor are not synthesized by the plant itself. They are produced by Periglandula clandestina, a vertically transmitted fungal endosymbiont first described in 2025.[1] The biosynthetic pathway follows the general ergot alkaloid route from tryptophan and dimethylallyl pyrophosphate, paralleling the pathway in Claviceps fungi.
Neuroscience[edit]
Where it acts
Ergine's psychoactive effects are presumed to arise primarily from partial agonism at 5-HT₂A serotonin receptors, the same mechanism established for LSD, psilocin, and other classical serotonergic psychedelics.[2][7] Additional activity at 5-HT₁A receptors likely contributes to the prominent sedation, while dopamine D₂/D₃ agonism and alpha-adrenergic activity mediate peripheral vasoconstriction and body load.[15]
What it changes
The heavy sedation and body load that distinguish morning glory from LSD may reflect ergine's higher relative activity at 5-HT₁A and D₂ receptors compared with its 5-HT₂A efficacy.[15] CYP2D6 is the principal metabolic enzyme for lysergic acid amides,[16] and individuals with poor-metabolizer phenotypes may experience prolonged, more intense effects at any given dose.[16] Tolerance likely develops rapidly via 5-HT₂A downregulation, with expected cross-tolerance to LSD and psilocybin.[2]
No neuroimaging studies with morning glory seeds or pure ergine have been published. Human pharmacokinetic parameters for ergine remain uncharacterized — available blood concentration data derives solely from forensic cases involving Argyreia nervosa seeds.[9] Whether the ratio of ergine to isoergine and ergonovine in crude seed extract modulates the qualitative character of the experience is unknown.
Subjective Effects[edit]
The morning glory seed experience is a sedation-heavy serotonergic psychedelic state characterized by visual distortions, altered cognition, introspective thought, and pronounced physical discomfort. Unlike LSD — to which ergine is most closely related — the experience is shorter, less visually elaborate, and dominated by body load, lethargy, and nausea that constitute a larger fraction of the total experience.[5] Set, setting, gastric state, and preparation method all shape the trajectory, though batch-to-batch alkaloid variability is the single largest source of unpredictability.
Compared with psilocybin mushrooms, the perceptual and cognitive domains overlap moderately, but morning glory's gastrointestinal and vasoconstrictive load is more pronounced and less predictable. The preparation method — whole seeds chewed versus cold water extraction — alters the nausea burden more than the perceptual character, though no controlled comparison exists.
Effect Grid
A clear psychedelic state with visual drifting, color alteration, and at the upper end, geometric patterning. Cognitive effects are prominent — altered thought patterns, introspection enhancement, thought connectivity, and emotional enhancement. Time alteration is distinct. Confusion may occur in waves. Emotional lability is possible.
Sedation and bodily heaviness dominate the physical experience. Nausea is often severe and may progress to vomiting. Vasoconstriction, muscle tension, and dizziness are common. Appetite suppression is pronounced. The body load distinguishes this from most other classical psychedelics at equivalent subjective intensity.
Duration is 4–7 hours with residual fatigue and lethargy persisting 12–24 hours. This is the dose range most commonly reported in user accounts. Dose-to-effect reliability is poor due to extreme alkaloid variability between seed batches.

Toxicity
No LD50 data for ergine in humans or animals exist in published literature. No controlled toxicity study for I. tricolor seeds has been conducted. safety citation needed
In a prospective study of related LSA-containing seeds (Argyreia nervosa) at body-weight-normalized doses, 3 of 4 subjects experienced severe adverse effects — cardiovascular disruption in 2 and a psychosis-like state in 1; all recovered within 9 hours.[7] One fatal case involved a person who fell from a building during LSA intoxication with co-ingested THC and ethanol, with a blood LSA concentration of 4.9 µg/L.[8]
Commercially sold ornamental seeds are routinely coated with pesticides and fungicides, presenting hepatotoxic and neurotoxic risk independent of ergoline content.[9] Treated seeds often show brightly colored surface residue, but the absence of visible coating does not guarantee safety. safety citation needed
Psychological Risks
Acute psychological adverse effects include anxiety, panic, confusion, and psychosis-like states at higher doses or in susceptible individuals.[7] Suicidal ideation has been documented in recreational users who ingested LSA-containing seeds.[4][8] Persons with a personal or family history of psychotic disorders, or with current depressive states, face elevated risk.
Tolerance & Dependence
Ergoline compounds show low physical dependence liability, consistent with low compulsive use patterns.[6] Rapid tolerance is expected within 3–4 days of repeated use, with cross-tolerance to LSD and psilocybin.[1] Ergotamine, a related ergot alkaloid, can produce a self-sustaining headache-medication dependence cycle;[16] whether ergine produces an analogous pattern at recreational doses is unknown.
Drug Interactions
Serotonergic agents (SSRIs, SNRIs, MAOIs, triptans): Combining morning glory with these drugs stacks serotonergic activity, raising the risk of a potentially life-threatening state involving high fever, rapid heart rate, and muscle rigidity.[15] Triptans combined with ergot alkaloids carry particular concern because both classes constrict blood vessels.[17]
Vasoconstrictors: Ergonovine in morning glory seeds already constricts blood vessels. Adding other vasoconstrictors raises the risk of reduced blood flow to limbs or organs.[17]
CNS depressants (alcohol, benzodiazepines, opioids): These deepen morning glory's sedative effects. The only documented LSA-related fatality involved co-ingestion of ethanol and THC.[8]
CYP2D6 inhibitors (fluoxetine, paroxetine, bupropion): These medications slow the liver's breakdown of ergine, potentially raising alkaloid levels and prolonging effects.[15]
Contraindications
Cardiovascular disease: vasoconstriction is a class effect of ergot alkaloids. Coronary artery disease, peripheral vascular disease, and Raynaud's phenomenon all increase ischemia risk.
Pregnancy: Ergonovine in morning glory seeds contracts the uterus. Ingestion during pregnancy carries risk of miscarriage.[11]
Personal or family history of psychosis: Risk of acute psychotic episode is extrapolated from the serotonergic psychedelic class.
Concurrent serotonergic medications: Serotonin toxicity risk as described in Drug Interactions above.
CYP2D6 poor metabolizers: May experience prolonged and more intense effects at standard doses.[15]
Hepatic impairment: Reduced clearance may prolong exposure. inferred
Preparations[edit]
Whole seeds (chewed)
Whole seeds (chewed) is the simplest preparation. Seeds are chewed thoroughly and swallowed, with onset typically within 30–60 minutes and effects lasting 4–8 hours. This method produces the most severe nausea because seed hulls, waxes, and any surface coatings are ingested directly. Dose prediction is unreliable — some commercial lots contain no detectable ergot alkaloids.[5]
Cold water extraction
Cold water extraction involves grinding seeds, soaking in cold water for several hours, then filtering out solids before drinking the liquid. The aim is to reduce nausea by removing indigestible seed matter while retaining water-soluble alkaloids. Onset and duration are comparable to whole-seed ingestion. No controlled study confirms this method meaningfully reduces gastrointestinal distress or alters alkaloid bioavailability.
Sublingual
Sublingual preparations hold ground seed material under the tongue to absorb alkaloids through the oral mucosa. This route is reported anecdotally to reduce nausea, but no published data confirm altered bioavailability or a distinct effect profile. Onset and duration are poorly characterized for this method.
Harm Reduction[edit]
Forms & Identification
Morning glory seeds sold for ornamental gardening carry no quality assurance for human consumption. The most critical identification concern is pesticide coating — treated seeds often show brightly colored residue, but the absence of visible coating does not guarantee safety.[9]
Lab testing for alkaloid content is not commercially available to consumers. Batch variability is extreme: 2 of 5 commercial lots in one analytical study contained zero detectable ergot alkaloids.[5] A given seed count can produce no effect or an unexpectedly intense one depending on source.
Guidelines
- Start with a fraction of the intended dose from any new batch — alkaloid content varies dramatically across sources
- Never consume seeds with visible colored coating or residue; these likely carry pesticide treatments
- Avoid combining with serotonergic medications (SSRIs, SNRIs, MAOIs, triptans), vasoconstrictors, or CNS depressants including alcohol
- Eat lightly several hours before ingestion to reduce nausea severity
- Have ginger tea or an antiemetic available for gastrointestinal distress
- Do not redose within the same session — delayed onset can produce unexpectedly strong effects if a second dose is taken prematurely
- Keep the environment calm, dimly lit, and free from obligations
Set & Setting
The morning glory experience includes pronounced nausea, sedation, and body load across 4–8 hours. A comfortable, private environment with easy bathroom access is essential. Driving or operating equipment is unsafe during and for several hours after ingestion.
A sober, trusted companion is strongly recommended — especially for anyone unfamiliar with psychedelic experiences. Anxiety-prone individuals or those in emotional distress face elevated risk of panic and paranoia.
Aftercare & integration. Nausea and physical discomfort typically resolve within 1–2 hours after peak effects subside. Hydration is important — vomiting and diarrhea during the experience can cause fluid loss. A light meal after effects have subsided helps restore energy.
Next-day effects may include fatigue, residual sedation, and mild mood changes. Allow a full rest day before resuming demanding cognitive tasks. If the experience was distressing, talking through it with a trusted person or an integration-focused therapist can help process difficult material.
Recovery & Support
Morning glory seeds carry low abuse liability as an ergoline compound class,[6] and compulsive use patterns are rare. However, persistent psychological distress following a difficult experience may warrant professional support.

Emergency Response
Recognizing an emergency:
- Severe chest pain or difficulty breathing (vasoconstrictive crisis)
- Unresponsiveness or inability to communicate
- Psychotic behavior — loss of contact with reality, aggression, self-harm
- Expressed suicidal ideation
- Seizures
Immediate steps:
- 1. Call emergency services immediately if any of the above signs are present
- 2. Keep the person in a safe, quiet environment and remove sharp objects
- 3. Do not physically restrain unless there is immediate danger of self-harm or harm to others
- 4. If conscious and cooperative, offer reassurance: the effects are temporary and will resolve
- 5. Monitor breathing and heart rate until help arrives
What to tell the dispatcher:
State that the person ingested morning glory seeds (containing LSA/ergine), the approximate number of seeds and time of ingestion, and all current symptoms. Mention any co-ingested substances. Good Samaritan laws exist in many jurisdictions and provide legal protection to callers reporting drug-related emergencies.
Reversal agents: No specific reversal agent for ergine toxicity exists. Treatment is supportive.
Legal Status[edit]
Morning glory plants and seeds are not scheduled under any United Nations drug convention.[18] The isolated alkaloid ergine is Schedule III under US federal law (since 1970), while seeds remain legal to possess and sell. Louisiana restricts seeds when intended for human consumption; Arizona classifies all Ipomoea species as noxious weeds. Canada places no restrictions on plants or seeds. In the United Kingdom, seeds are legal to possess but extracted LSA is controlled under the Misuse of Drugs Act.[9] Italy classifies morning glory seeds as controlled narcotic drugs; most other EU member states impose no restrictions on plants or seeds.[18] Australia permits domestic possession and cultivation but prohibits import and export, with most states restricting consumption of LSA-containing seeds.[18]
Legal status changes frequently. This overview reflects the status as of the article's last update and is not legal advice. Verify current law in the relevant jurisdiction before acting on this information.

Toxicity
No LD50 data for ergine in humans or animals exist in published literature. No controlled toxicity study for I. tricolor seeds has been conducted. safety citation needed
Available evidence derives from case reports involving LSA-containing seeds. In a prospective study of Argyreia nervosa seeds at body-weight-normalized doses, 3 of 4 subjects experienced severe adverse effects — cardiovascular dysregulation in 2 and a psychosis-like state in 1; all recovered within 9 hours.[8] A fatal case involved an individual who fell from a building during LSA intoxication with co-ingested THC and ethanol, with a blood LSA concentration of 4.9 µg/L.[9]
Commercially sold ornamental morning glory seeds are routinely treated with pesticide and fungicide coatings, presenting hepatotoxic and neurotoxic risk independent of ergoline alkaloid content.[10] Treated seeds may be identifiable by brightly colored dust on the surface, but no reliable consumer method confirms the absence of treatment. The specific pesticides used have not been systematically identified in published literature. safety citation needed
No published data on heavy metal contamination, mycotoxin co-contamination, or microbial load specific to I. tricolor seeds as a recreational preparation were identified. No ISO/IEC-accredited laboratory testing program or Certificate of Analysis requirement exists for morning glory seeds sold as ornamental products.
Psychological Risks
Acute psychological adverse effects include anxiety, panic, confusion, and psychosis-like states at higher doses or in susceptible individuals.[8] Suicidal ideation has been documented in recreational users who ingested A. nervosa and Ipomoea seeds.[5] One forensic case survivor described suicidal ideation following A. nervosa seed ingestion.[9]
The risk of precipitating persistent psychosis in predisposed individuals is analogous to other serotonergic psychedelics as a class. Persons with personal or family history of psychotic disorders or current depressive states with suicidal ideation face elevated risk.
Tolerance & Dependence
No systematic study of tolerance development for ergine has been conducted. By analogy with LSD and other serotonergic psychedelics, rapid tachyphylaxis is expected — tolerance developing within 3–4 days of repeated use — with cross-tolerance to LSD, psilocybin, and other serotonin 2A receptor agonists.[2]
Ergoline compounds as a class show low physical dependence liability, consistent with low compulsive use patterns.[7] Ergotamine, a related ergot alkaloid used medicinally, can produce a physical dependence syndrome characterized by a self-sustaining headache-medication cycle;[17] whether ergine produces analogous dependence at recreational doses is unknown.
Drug Interactions
Serotonergic agents (SSRIs, SNRIs, MAOIs, triptans): Additive serotonergic activity at 5-HT₂A and 5-HT₁A receptors raises theoretical serotonin syndrome risk.[16] The triptan–ergot combination is of particular concern given the vasoconstrictive properties of both drug classes.[18]
Vasoconstrictors: Ergot alkaloids including ergonovine have potent vasoconstrictor activity. Co-administration with other vasoconstrictors increases ischemia risk.[18]
CNS depressants (alcohol, benzodiazepines, opioids): Additive CNS depression. The sole documented fatality involving LSA-containing seeds involved co-ingestion of ethanol and THC.[9]
CYP2D6 inhibitors (fluoxetine, paroxetine, bupropion): May increase ergine plasma levels and effect duration via reduced hepatic metabolism.[16]
Contraindications
Cardiovascular disease: Ergot alkaloid vasoconstriction is a class effect. Individuals with coronary artery disease, peripheral vascular disease, or Raynaud's phenomenon face elevated ischemia risk.
Pregnancy: Ergonovine is a documented uterotonic agent. Morning glory seeds contain ergonovine; ingestion during pregnancy carries risk of uterine contraction and miscarriage.[12]
Personal or family history of psychosis: Risk of acute psychotic episode is extrapolated from the serotonergic psychedelic class.
Concurrent serotonergic medications: Serotonin toxicity risk as described in Drug Interactions above.
CYP2D6 poor metabolizers: May experience prolonged and more intense effects at standard doses.[16]
Hepatic impairment: Reduced CYP-mediated clearance may prolong exposure. inferred
Preparations[edit]
Whole seeds (chewed)
Whole seeds (chewed) is the simplest preparation method. Seeds are chewed thoroughly and swallowed. Onset typically occurs within 30–60 minutes, with effects lasting 4–8 hours. This method produces the most severe nausea and gastrointestinal distress because the seed material itself — including hull waxes and any surface coatings — is ingested directly. Dose prediction is unreliable due to batch alkaloid variability; some commercial seed lots contain no detectable ergot alkaloids.[6]
Cold water extraction
Cold water extraction involves grinding seeds and soaking them in cold water for several hours, then filtering out the solid material before drinking the liquid. This method aims to reduce nausea by removing indigestible seed matter while retaining water-soluble ergoline alkaloids. Onset and duration are comparable to whole-seed ingestion. No controlled study has confirmed whether this method meaningfully reduces gastrointestinal adverse effects or alters alkaloid bioavailability.
Sublingual
Sublingual preparations involve holding ground seed material under the tongue to absorb alkaloids through the oral mucosa. This route is reported anecdotally to reduce nausea by bypassing gastric exposure, but no published data confirm altered bioavailability or effect profile. Duration and onset are poorly characterized for this method.
Harm Reduction[edit]
Forms & Identification
Morning glory seeds sold for ornamental gardening are not intended for human consumption and carry no quality assurance for that purpose. The critical identification concern is pesticide and fungicide coating — treated seeds often show brightly colored residue, but absence of visible coating does not guarantee safety.[10]
Lab testing for ergoline alkaloid content is not commercially available to consumers. Batch variability is extreme: analytical testing found 2 of 5 commercial lots contained zero detectable ergot alkaloids.[6] Seed count is not a reliable proxy for dose — identical numbers of seeds from different sources may produce no effects or unexpectedly strong effects.
Guidelines
- Start with a fraction of the intended dose from any new batch — alkaloid content varies dramatically across sources
- Never consume seeds with visible colored coating or residue; these likely carry pesticide treatments
- Avoid combining with serotonergic medications (SSRIs, SNRIs, MAOIs, triptans), vasoconstrictors, or CNS depressants including alcohol
- Eat lightly several hours before ingestion to reduce nausea severity
- Have ginger tea or an antiemetic available for gastrointestinal distress
- Do not redose within the same session — delayed onset can produce unexpectedly strong effects if a second dose is taken prematurely
- Keep the environment calm, dimly lit, and free from obligations
Set & Setting
The morning glory experience includes pronounced nausea, sedation, and body load. A comfortable, private environment with easy access to a bathroom is strongly advised. The 4–8 hour duration requires planning; driving or operating equipment is unsafe during and for several hours after ingestion.
A sober, trusted companion is recommended, especially for anyone unfamiliar with psychedelic experiences. Anxiety-prone individuals or those in an unstable emotional state face elevated risk of panic and paranoia.
Aftercare & integration. Nausea and physical discomfort typically resolve within 1–2 hours after peak effects subside. Hydration is important — vomiting and diarrhea during the experience can cause fluid loss. A light meal after effects have subsided helps restore energy.
Next-day effects may include fatigue, residual sedation, and mild mood changes. Allow a full rest day before resuming demanding cognitive tasks. If the experience was distressing, talking through it with a trusted person or an integration-focused therapist can help process difficult material.
Recovery & Support
Morning glory seeds carry low abuse liability as an ergoline compound class,[7] and compulsive use patterns are rare. However, persistent psychological distress following a difficult experience may warrant professional support.
For ongoing distress, anxiety, or mood disruption following use, contact:
- SAMHSA National Helpline: 1-800-662-4357 (US, free, confidential, 24/7)
- Fireside Project: 62-FIRESIDE (US psychedelic peer support line)
- Crisis Text Line: Text HOME to 741741 (US)
If recurrent use is causing functional impairment, a mental health professional with experience in substance use can help develop a cessation plan.

Emergency Response
Recognizing an emergency:
- Severe chest pain or difficulty breathing (vasoconstrictive crisis)
- Unresponsiveness or inability to communicate
- Psychotic behavior — loss of contact with reality, aggression, self-harm
- Expressed suicidal ideation
- Seizures
Immediate steps:
- 1. Call emergency services immediately if any of the above signs are present
- 2. Keep the person in a safe, quiet environment and remove sharp objects
- 3. Do not physically restrain unless there is immediate danger of self-harm or harm to others
- 4. If conscious and cooperative, offer reassurance: the effects are temporary and will resolve
- 5. Monitor breathing and heart rate until help arrives
What to tell the dispatcher:
State that the person ingested morning glory seeds (containing LSA/ergine), the approximate number of seeds and time of ingestion, and all current symptoms. Mention any co-ingested substances. Good Samaritan laws exist in many jurisdictions and provide legal protection to callers reporting drug-related emergencies.
Reversal agents: No specific reversal agent for ergine toxicity exists. Treatment is supportive.
Legal Status[edit]
Morning glory plants and seeds (Ipomoea tricolor) are not scheduled under any United Nations drug convention — neither the 1961 Single Convention on Narcotic Drugs, the 1971 Convention on Psychotropic Substances, nor the 1988 Convention against Illicit Traffic.[13] The isolated alkaloid ergine (d-lysergic acid amide) is separately controlled in some jurisdictions while the plant material itself remains legal in most. This creates a jurisdiction-specific legal landscape in which seed possession is typically lawful but alkaloid extraction is not.
| Jurisdiction | Classification | Key provisions |
|---|---|---|
| United States (federal) | Plant/seeds legal; ergine Schedule III (CSA, 1970) | Possession and sale of I. tricolor plants and seeds is lawful. Isolated ergine (LSA) is Schedule III. Commercial extraction is explicitly illegal; home extraction occupies a legal gray area.[13] |
| Arizona (US state) | Restricted | All Ipomoea species classified as noxious weeds; possession may constitute a misdemeanor.[13] |
| Louisiana (US state) | Restricted for consumption | Illegal when intended for human consumption (effective August 8, 2005); legal for aesthetic, landscaping, or decorative purposes.[13] |
| Canada | Legal (plants and seeds) | No restrictions on possession of morning glory plants or seeds.[13] |
| United Kingdom | Seeds legal; extracted LSA controlled | Seeds may be legally possessed. Extracted LSA is a controlled substance under the Misuse of Drugs Act.[10] |
| Italy | Controlled narcotic | Morning glory seeds classified as controlled narcotic drugs.[13] |
| Most EU member states | Legal (plants and seeds) | Belgium, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Netherlands, Poland, Romania, and most other member states impose no restrictions on plants or seeds.[13] |
| Australia | Plants legal; import prohibited | Plants and seeds legal to possess and cultivate domestically. Import and export of I. violacea, I. tricolor, and I. hederacea prohibited under the Customs Act. Most Australian states restrict consumption of LSA-containing seeds under state legislation.[13] |
Analog and treaty considerations
Ergine is not listed in UN international drug schedules. In the United States, the Federal Analogue Act (21 U.S.C. § 813) could theoretically apply to related lysergamides found in morning glory seeds if intended for human consumption, though prosecution under this provision for plant material is not documented in available case law. citation needed
Frequently asked questions
What is Morning glory?
Morning glory refers to Ipomoea tricolor, a Convolvulaceae vine whose seeds contain ergoline alkaloids produced by a fungal endosymbiont. The principal alkaloid, ergine (LSA), is a presumed 5-HT2A partial agonist with no published binding data or controlled human trials.
What are dangerous combinations with Morning glory?
The highest-severity documented interactions for Morning glory: MAOIs (Lethal), Dopamine agonists (Dangerous), GHB, Baclofen (Dangerous), GHB, GBL (Dangerous), Ibogaine (Dangerous). See the interactions section for the full list with mechanisms and severity levels.
Is Morning glory addictive?
Psychedex records tolerance and dependence data rather than a yes/no rating. Recorded tolerance indicators for Morning glory: tolerance builds rapid; full reset takes 10 days; cross-tolerance develops with LSD, psilocybin, mescaline. See the article's dependence and safety sections for recorded dependence data.
