The root of Adonis vernalis contains a glucoside named adonidin. It is allied in action to digitoxin, one of the principles of digitalis, but is more irritating to the digestive organs.

Physiological Actions

Adonidin stimulates the heart and vaso-motor centers under some circumstances. It is not cumulative in tendency. It has no special power as a diuretic, though there may be some slight action resulting from the effect upon circulation in the kidneys.

In overdoses adonidin produces vomiting and diarrhoea.
