Ankaferd BloodStopper (ABS) is a licensed medicinal plant product that provides active hemostasis in external, postsurgical and dental bleeding, and is approved in Turkey by the Ministry of Health. The use of ABS for internal organ hemorrhage is under investigation. Our clinic is one of the certified centers conducting a phase II trial investigating the effects and reliability of ABS in urogenital surgery. We have used ABS to stop bleeding during radical retropubic prostatectomy in one patient, presented here as a case report.
