squill, sea squill, sea onion, Meerzwiebel

Perennial herb, native to southern Europe (Spain), the Mediterranean, and northern Africa; large bulb up to 15cm wide; leaves laethery, ark green, usualy 50cm long, coming up in sping and dying away in summer; inflorescence developing in autumn, reaching up to 150cm in height; petals white with green.

Intoxication „effects resembling those seen with cardiac glycoside intoxication included nausea, vomiting, seizures, hyperkalemia, atrioventricular block and ventricular arrhythmias resembling digitalis toxicity.“
[Urginea maritima (squill) toxicity. Tuncok, Yesim, et al., Clinical Toxicology, Vol.33(1), 1995, 83-86]

The sliced and rapidly dried fleshy inner bulb scales (Scillae bulbus) were used as heart tonic (NYHA I and II) and diuretic. D.maritima contain cardiac glucosides of the bufadienolide type like glucoscillaren A and scillaren A (which yield proscillaridin A on hydrolysis) with positive inotropic and weakly negative chronotropic heart activity, and expectorant, diuretic and emetic effects. „Squill powder or extracts are poisonous and should be used under professional supervision.“
[Medicinal Plants of the World. Ben-Erik Van Wyk and Michael Wink, Pretoria 2004, 331]

From thirty three compounds obtained from the bulbs of Urginea maritima, nine were cardiotonic bufadienolides (mainly scillaren A, scilliroside and proscillaridin A) and one a dihydro-benzofuran-type neolignan glucoside.
