Summer adonis, a discreet scarlet star of Europe's grain fields, owes its name to the legend of beautiful Adonis, whose blood was said to have given rise to its red petals. A cousin of spring adonis, it was long observed by herbalists for its recognized action on the heart and circulation, before being supplanted by better-dosed, standardized preparations. Its toxicity, known for centuries, makes it today a plant of history more than of everyday practice.
Summer adonis was traditionally used, like foxglove, to support a tired or irregular heart, particularly in the countryside of Central and Eastern Europe.
Old herbalists attributed to it a tonic action on circulation, used with great caution in cases of diagnosed heart weakness.
Combined with other cardiotonic plants, it was sometimes used to relieve breathlessness linked to a weak heart, more a side effect of its cardiac action than a direct respiratory use.
Folk tradition recognized in it mild diuretic properties, often sought as a complement to its cardiac action in cases of cardiac edema.
A toxic plant containing cardiotonic glycosides similar to those of foxglove: any internal use must be supervised by a qualified healthcare professional, and never self-administered. Formally contraindicated in pregnancy, breastfeeding, children, and in cases of already-treated heart conditions. High risk of interaction with cardiac treatments (digitalis drugs, beta-blockers, diuretics) and certain medications: never combine without medical advice. Confusion with digitalis glycosides can lead to serious overdose; the margin between an effective dose and a toxic one is very narrow.
