   • 2012, Perera N, Liolitsa D, Iype S, Croxford A, Yassin M, Lang P, Ukaegbu O, van Issum C, “Phlebotonics for haemorrhoids”, in Cochrane Database of Systematic Reviews, volume 15, number 8, →DOI, →PMID, page CD004322:

     Phlebotonics are a heterogeneous class of drugs used to treat haemorrhoidal disease in the less severe stages of first and second-degree haemorrhoids, and during the thrombosis episodes. Although their true mechanism of action has not been well established, they are associated with strengthening of blood vessel walls, increasing venous tone, lymphatic drainage and normalizing capillary permeability. We considered twenty four studies for inclusion in this review. This review identified twenty randomised controlled trials enrolling a total of (2334) participants which compared an intervention using phlebotonics with a control intervention.
