Rutivite tablets are made from the finest quality flowers and leaves of the Green Buckwheat plant. This herb contains a flavonoid called Rutin, an active ingredient known to offer nutritional support to the circulatory system with no side effects. Rutin is believed to be especially helpful in preventing recurrent bleeding caused by weakened blood vessels, so it has been used in the treatment of haemorrhoids and varicose veins, helping to prevent blood vessel walls becoming fragile. Rutin is also taken by many as a preventative measure against thrombosis.
