LSA Dosage Calculator

LSA (d-lysergic acid amide, also called ergine) is a naturally occurring psychedelic found in Hawaiian Baby Woodrose (Argyreia nervosa) seeds and Morning Glory (Ipomoea tricolor) seeds. LSA is structurally related to LSD but produces a distinct experience — more sedating, dreamy, and introspective with less visual stimulation. Hawaiian Baby Woodrose seeds are far more potent per seed than Morning Glory, requiring only 4-8 seeds for a moderate experience versus 150-300 Morning Glory seeds. The most common side effects are nausea, vasoconstriction (cold extremities), and lethargy. Cold water extraction (CWE) can significantly reduce nausea while preserving psychoactive effects. This calculator accounts for seed type, count, preparation method, and your experience level.

About LSA (d-Lysergic Acid Amide)

LSA (ergine, d-lysergic acid amide) is a naturally occurring psychedelic alkaloid found in the seeds of several plant species, most notably Hawaiian Baby Woodrose (Argyreia nervosa) and Morning Glory (Ipomoea tricolor, especially the Heavenly Blue variety). LSA is structurally closely related to LSD — both share the lysergic acid backbone — but LSA produces a distinctly different experience. Where LSD is stimulating and visually intense, LSA is sedating, dreamy, and more introspective. LSA primarily activates serotonin 5-HT2A receptors (responsible for psychedelic effects) but also has significant activity at dopamine D1 and D2 receptors, contributing to its unique sedative and uplifting character. It is classified as an ergot alkaloid.

Hawaiian Baby Woodrose vs. Morning Glory

Hawaiian Baby Woodrose (Argyreia nervosa) seeds are among the most potent natural sources of LSA, containing approximately 0.3-1.0% ergine alkaloids by weight. A single seed weighs about 1-3 grams and contains 200-500 mcg of LSA. Morning Glory (Ipomoea tricolor) seeds contain significantly less LSA per seed — approximately 0.01-0.05% by weight. Each seed weighs only about 30-50mg, containing roughly 5-15 mcg of LSA. This means you need roughly 50-75 Morning Glory seeds to match one HBWR seed. HBWR tends to produce more body load, sedation, and nausea. Morning Glory is often described as producing a lighter, more visual, and less physically heavy experience.

Cold Water Extraction Method

Cold water extraction (CWE) is the most recommended preparation method for LSA seeds because it dramatically reduces nausea while preserving most of the psychoactive content. Crush your seeds thoroughly (mortar and pestle or coffee grinder), place the powder in cold distilled or spring water (not tap water — chlorine degrades LSA), and soak in a dark container for 2-4 hours. LSA is water-soluble but light-sensitive and heat-sensitive. Strain through a coffee filter or fine cloth, discard the seed material, and drink the liquid. Some users add a small amount of peppermint to improve flavor. Potency loss compared to eating whole seeds is estimated at 10-25%.

Reducing Nausea from LSA Seeds

Nausea is the most common complaint with LSA seeds. Multiple strategies can minimize it: (1) Use cold water extraction instead of eating raw seeds. (2) For HBWR seeds, carefully remove the fuzzy brown outer coating — it contains compounds that worsen nausea. (3) Fast for 4-6 hours before consumption. (4) Consume 1-2g of ginger root or drink ginger tea 30 minutes beforehand. (5) Take seeds in capsules to bypass the unpleasant taste (taste-induced nausea is real). (6) Remain still and avoid sudden movements during onset. (7) Accept that some nausea is likely and usually passes within 60-90 minutes.

Safety Guidelines

Start with a low dose, especially with HBWR seeds where potency varies between batches. The most important safety concern with LSA is vasoconstriction — if your extremities become painfully cold, numb, or discolored (blue/white), this may indicate dangerous vasoconstriction. Stay warm, move gently, and seek medical attention if symptoms are severe. Never combine LSA with lithium (seizure risk), other psychedelics (unpredictable potentiation), or vasoconstrictive substances (caffeine, amphetamines). Set and setting matter — use in a comfortable, safe environment. The experience is heavily sedating; do not plan to go anywhere. Do not drive for at least 12 hours after ingestion.

Frequently Asked Questions

How many Hawaiian Baby Woodrose seeds should I take?

For a first experience, 3-5 HBWR seeds is recommended. A moderate dose is 5-8 seeds, and a strong dose is 8-12 seeds. Potency varies between seed batches. Always remove the fuzzy outer coating, which contains compounds that worsen nausea. Cold water extraction is strongly recommended for first-timers.

How many Morning Glory seeds for a trip?

Morning Glory seeds contain much less LSA per seed than HBWR. A threshold dose is 50-100 seeds, a light dose is 100-200, a moderate dose is 200-400, and a strong dose is 400-600 seeds. Only use untreated seeds — commercially sold decorative seeds are often coated with pesticides or emetic chemicals that cause severe vomiting.

What is cold water extraction for LSA seeds?

Cold water extraction (CWE) involves crushing seeds, soaking them in cold distilled water for 2-4 hours in the dark, straining out the seed matter, and drinking only the liquid. This separates the water-soluble LSA from the nausea-causing oils, waxes, and glycosides in the seed material. Effects may be slightly reduced compared to eating whole seeds, but nausea is dramatically decreased.

How long does an LSA trip last?

LSA experiences typically last 6-10 hours. Onset is slow — 1-2 hours before effects become apparent, with nausea often peaking at 30-90 minutes. Peak psychedelic effects occur at 3-5 hours and gradually taper. Strong sedation and a dreamy, introspective state are common throughout. Many users fall asleep during the comedown.

What is the difference between HBWR and Morning Glory seeds?

Hawaiian Baby Woodrose seeds are much more potent per seed — one HBWR seed contains roughly the LSA equivalent of 50-75 Morning Glory seeds. HBWR also tends to produce more body load (sedation, vasoconstriction, nausea). Morning Glory seeds are milder per seed and the experience is often described as lighter and more visual. Both contain the same primary active compound (LSA/ergine).

Why do LSA seeds cause nausea?

LSA seeds contain ergot-type alkaloids alongside waxes, oils, cyanogenic glycosides, and other compounds that irritate the gastrointestinal tract. The nausea is primarily caused by these non-psychoactive compounds, not the LSA itself. Cold water extraction removes most of these nauseating materials. Removing the outer seed coating of HBWR seeds also helps significantly.

Can you build tolerance to LSA?

Yes, cross-tolerance develops rapidly between LSA and other serotonergic psychedelics (LSD, psilocybin). After a single use, tolerance is near-complete for 2-3 days and takes approximately 7-14 days to fully reset. Taking LSA within a week of LSD or psilocybin will result in diminished effects.
