An infusion of flowers (2 teaspoons per glass of boiling water) is recommended in folk medicine as a remedy for chronic constipation and liver diseases. A tincture of fresh leaves and seeds has been tried in heart failure. Cheirotoxin increases the amplitude of heart contractions and slows down its rhythm.
