Sea Squill

Scilla maritima

Sea Squill has one of the longest documented histories of any Mediterranean bulb, noted by ancient Egyptian physicians and later by Greek and Roman writers, including Pythagoras, who is said to have written a treatise on it. For centuries, apothecaries prepared the dried bulb into tinctures, oxymels, and pills used under close medical supervision as an expectorant for coughs and as a heart stimulant, much the way foxglove came to be used. That same potency made it equally famous for a very different purpose: powdered squill bulb, especially the deep red variety, became a widely used rat poison, since rodents lack the ability to vomit and expel it. Today its traditional medicinal role has been almost entirely replaced by safer, standardized pharmaceuticals, and the plant survives mostly as a striking ornamental and a reminder of how thin the line once was between remedy and poison.

Safety.

Sea Squill is toxic and must never be ingested or self-prescribed. Every part of the plant, especially the large bulb, contains potent cardiac glycosides (including scillaren A and scilliroside) that act on the heart in the same family of compounds as foxglove. Even modest amounts can cause nausea, vomiting, dangerous heart arrhythmias, and in sufficient quantity, death. This toxicity is precisely why the dried, powdered bulb was used for centuries as a rodenticide, rats and mice cannot vomit to expel it, while larger mammals who can vomit are somewhat, but not reliably, protected. Sea Squill is unsafe in pregnancy, is dangerous alongside any heart medication (including digoxin), and has no place in home remedies. Historically, physicians used carefully calibrated, pharmaceutical-grade preparations of squill under close supervision, and that history belongs to medicine, not to the kitchen or garden shed. If you are drawn to this plant for any therapeutic reason, please speak with a qualified healthcare provider rather than attempting to prepare it yourself.
