What Is LSA?

This guide is written for adults aged 18 and over. Effects, dosing ranges, and safety data described below apply to adult physiology.

Key Facts

• Chemical identity: D-lysergic acid amide (ergine), a naturally occurring ergoline alkaloid structurally related to LSD (Hofmann, 1963).
• Primary sources: Seeds of Turbina corymbosa (ololiuqui), Argyreia nervosa (Hawaiian baby woodrose / HBWR), and Ipomoea tricolor (morning glory).
• Receptor activity: Partial agonist at serotonin 5-HT_2A receptors, with additional affinity for dopamine D₂ and 5-HT_1A receptors (Paulke et al., 2013).
• Duration: Reported effects last 6–10 hours depending on source material and dose.
• Historical record: Aztec ceremonial use of ololiuqui documented in the Florentine Codex (16th century); ergine identified as the active compound by Albert Hofmann in 1963.
• Safety profile: Low acute toxicity at common doses, but pronounced vasoconstrictive and gastrointestinal side effects are widely reported (Klinke et al., 2010).
• Forms available: Whole seeds (morning glory, HBWR), seed extracts, and occasionally isolated ergine in research contexts.

Contraindications

LSA carries specific risks for certain populations. These should be reviewed before looking at dosage ranges.

History and Origin

The earliest documented use of LSA-containing seeds comes from 16th-century Spanish colonial records. Bernardino de Sahagún described Aztec priests consuming ololiuqui — the seeds of Turbina corymbosa — in divinatory rituals, noting that the seeds produced visions and were treated with reverence bordering on worship. The Spanish Inquisition tried to suppress the practice, which only pushed it underground.

AZARIUS · History and Origin

For centuries, Western science ignored ololiuqui. That changed in 1941 when Richard Evans Schultes, the father of modern ethnobotany, positively identified the plant and confirmed its continued ceremonial use among Zapotec and Mazatec communities in Oaxaca. But the real bombshell came in 1963, when Albert Hofmann — yes, the same chemist who synthesised LSD — isolated ergine from Turbina corymbosa and Ipomoea tricolor seeds and recognised its structural kinship with his more famous creation (Hofmann, 1963). Hawaiian baby woodrose (Argyreia nervosa), native to the Indian subcontinent, was later found to contain significantly higher concentrations of ergine per seed, making it the most potent natural source known.

Chemistry and Active Compounds

Ergine (D-lysergic acid amide) belongs to the ergoline family — a group of compounds built around a tetracyclic ring structure shared with LSD, ergotamine, and several pharmaceutical drugs. The structural difference between LSA and LSD is small but pharmacologically significant: LSD carries a diethylamide group where LSA has a simple amide. This makes LSA roughly 10–20 times less potent at the 5-HT_2A receptor, though direct comparative binding data in humans remain sparse.

AZARIUS · Chemistry and Active Compounds

LSA-containing seeds are not single-compound preparations. They contain a cocktail of related ergoline alkaloids, and the overall experience likely reflects their combined activity rather than ergine alone.

The relative ratios of these alkaloids vary between species, individual seed batches, and even growing conditions. Published K_i values for ergine itself come primarily from in vitro assays, and how closely these translate to human receptor occupancy at oral doses is still not well characterised — most of the pharmacokinetic data we have is extrapolated from structurally related ergolines rather than measured directly for ergine.

Effects Overview

The subjective effects of LSA sit somewhere between a low-dose LSD experience and a sedative — which is an odd combination that confuses people who expect something purely stimulating. The serotonergic component produces visual changes (enhanced colour saturation, pattern recognition, mild open-eye visuals at higher doses) and introspective thought patterns. The dopaminergic and other ergoline activity adds a dreamy, sometimes heavy-bodied sedation that LSD does not produce. According to Klinke et al. (2010), commonly reported effects include altered perception, mood elevation, and a contemplative mental state alongside notable physical side effects.

AZARIUS · Effects Overview

Nausea is the elephant in the room. Nearly every account of LSA use mentions gastrointestinal discomfort — cramping, nausea, sometimes vomiting — particularly in the first 60–90 minutes. This is likely caused by the non-ergine alkaloids and other seed constituents rather than ergine itself, though isolating the cause definitively is difficult given the multi-alkaloid profile.

Dosage Guide

Dosage ranges below are drawn from published case reports, ethnobotanical literature, and user-reported data aggregated by harm-reduction organisations (Erowid, 2024; Klinke et al., 2010). They are not recommendations. Individual sensitivity varies considerably, and seed potency is not standardised — two batches of HBWR seeds can differ meaningfully in alkaloid content.

Hawaiian Baby Woodrose (Argyreia nervosa) Seeds

Morning Glory (Ipomoea tricolor) Seeds

Doses above 12 HBWR seeds or 400 morning glory seeds fall outside the range covered in published literature and carry significantly increased risk of severe vasoconstriction, prolonged nausea, and psychological distress.

Preparation Methods

The method of preparation affects both onset time and — critically — the severity of nausea. Raw seeds contain not just ergoline alkaloids but also cyanogens, oils, and other irritants that hammer the stomach. Most preparation methods aim to extract the water-soluble alkaloids while leaving behind the worst of the gut-punishing material.

Cold Water Extraction

The most common approach. Seeds are crushed (a coffee grinder works), soaked in cold, non-chlorinated water for 2–8 hours, then strained through a fine cloth. The liquid is consumed; the seed matter is discarded. This reduces nausea compared to eating whole seeds, though it does not eliminate it. Some people add a small amount of citric acid (lemon juice) to the soak, which may improve alkaloid solubility, though controlled data on this are lacking.

Sublingual / Chewing

Chewing seeds thoroughly and holding the mash under the tongue for 15–20 minutes before spitting out the plant matter. This bypasses first-pass metabolism and may reduce gastrointestinal load. Onset tends to be faster (20–40 minutes). The taste is bitter and unpleasant.

Whole Seed Ingestion

Eating seeds directly — chewed or swallowed — is the simplest method but produces the most nausea. The outer husk of HBWR seeds in particular is thought to contain much of the irritant material. Removing the fuzzy outer coating by scraping or light toasting may help marginally.

Safety and Drug Interactions

The acute toxicity of ergine at doses found in typical seed consumption appears to be low. No confirmed fatalities from LSA-containing seeds alone have been reported in the peer-reviewed literature, though emergency department presentations do occur — primarily from severe nausea, anxiety, and vasoconstriction (Klinke et al., 2010). The RIVM (Dutch National Institute for Public Health and the Environment) has documented cases of hospitalisation involving HBWR seeds, typically when consumed at high doses or in combination with other substances.

Common Side Effects

• Nausea and vomiting — near-universal, especially with whole seed ingestion
• Vasoconstriction — cold extremities, leg cramps, reported in most accounts. Related to the broader ergoline alkaloid profile, not just ergine
• Anxiety and thought loops — particularly at higher doses or in unfamiliar settings
• Fatigue — during and after the experience; next-day tiredness is common
• Muscle tension — jaw clenching, back and leg tightness

Less Common but Documented

• Transient hypertension — blood pressure elevation during the experience (Klinke et al., 2010)
• Psychotic episodes — rare, primarily in individuals with pre-existing vulnerability (Johnson et al., 2018)
• Persistent anxiety — reported in some cases lasting days after a difficult experience

A significant unknown is the long-term safety profile of repeated ergoline alkaloid exposure from seeds. The pharmaceutical ergoline literature (covering drugs like ergotamine and methysergide) documents cardiac valvulopathy and retroperitoneal fibrosis with chronic use, but whether the much lower doses from occasional seed consumption carry similar risks has not been studied. This is a genuine gap in the evidence — absence of harm data is not the same as evidence of safety.

Drug Interaction Table

LSA Compared to LSD

People often assume LSA is simply "natural LSD." The structural similarity is real — Hofmann himself noted it — but the experiential and pharmacological profiles diverge in important ways.

The sedating, inward quality of LSA is its most distinctive feature. Where LSD often feels electric and expansive, LSA tends toward something quieter — more like lying in a dark room with your thoughts than standing on a mountain watching the world breathe. Whether that appeals to you is a matter of preference, not quality.

Set and Setting

Set and setting matter for any psychoactive substance that alters perception, and LSA is no exception. A few practical points specific to this compound:

• Plan for nausea. Have a bucket, ginger tea, or anti-nausea ginger capsules ready. The first 60–90 minutes can be rough. Being near a bathroom helps.
• Comfortable, warm environment. Vasoconstriction can make you feel cold. Blankets, warm socks, a heated room — these are not luxuries, they are practical harm reduction.
• Clear schedule. With a 6–10 hour duration plus next-day fatigue, you need a full day clear. Not an evening-before-work substance.
• Sober companion. Especially at higher doses, having someone present who is not under the influence provides both safety and reassurance.
• Empty stomach or light meal. Eating a large meal before consuming seeds makes nausea significantly worse. A light snack 2–3 hours before is a reasonable middle ground.

Emergency Information

If someone experiences severe symptoms — persistent vomiting, chest pain, signs of psychosis, or loss of consciousness — call emergency services immediately.

• Netherlands: 112
• EU-wide emergency number: 112
• Dutch Poisons Information Centre (NVIC): +31 30 274 8888
• UK: 999 or 111 (NHS non-emergency)

Tell medical staff exactly what was taken, how much, and when. If possible, show them the seed packaging. Medical professionals are there to help, not to judge. Accurate information saves time and potentially lives.
