These components relax and dilate the arteries, particularly the coronary artery, increasing blood flow to the heart muscles and reducing symptoms of angina. Bioflavonoids are also powerful antioxidants and help prevent or reduce the degeneration of blood vessels.

Its key actions are:

• Dilation of blood vessels
• Cardiotonic action
• Relaxing action
• Antioxidant action

The liquid extract of the plant is advised for angina, while the dried fruits of the plant can be prepared as astringent decoction and are very effective against diarrhea.
