Proanthocyanidin is used in the treatment of varicose veins.

Proanthocyanidin is a polyphenolic compound that is extracted from grape seeds. It is an antioxidant with anti-inflammatory and vasodilating properties. It helps to dilate the constricted blood veins to reduce the tension on the blood vessels to restore normal blood flow. This is how it works to treat the symptoms of varicose veins such as itching, heaviness, swelling, and pain.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
