A poisonous ornamental bulb whose health value lies not in the plant but in two compounds it contains. Its purified compound galantamine has strong evidence for easing early-dementia memory symptoms and clear, smaller-scale evidence for boosting vivid, self-aware dreaming. A second compound shows only laboratory promise. The plant itself is genuinely dangerous to eat. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Resting heart rate / ECG | 60–90 bpm; no new conduction block | Galantamine can slow the heart and worsen conduction |
| Estimated glomerular filtration rate (eGFR) | >90 mL/min/1.73 m² | Reduced kidney function raises drug levels and side effects |
| Alanine aminotransferase (ALT) / liver panel | <25 U/L (functional); <40 U/L (conventional) | Liver enzymes CYP2D6/CYP3A4 clear galantamine |
| Body weight | Stable; unintended loss <5% | Nausea and appetite loss can cause weight decline |
| Blood pressure (supine and standing) | <120/80 mmHg; <20 mmHg drop on standing | Detects fainting/low-pressure risk from cholinergic effect |
Cadence: Heart rate and symptoms at 1 week, 4 weeks, and each dose increase, then every 3–6 months once stable; kidney and liver panels every 6–12 months or sooner if side effects appear.
