NCT07128979 ↗	Efficacy and Safety Evaluation of Ruscus Aculeatus L in Patients With Hemorrhoids	RECRUITING	Atabay Kimya Sanayi Ticaret A.S.	PHASE4	2025-08-01	Hemorrhoidal disease is characterized by distal displacement and deterioration of structural integrity of vascular cushions in the anal canal, which physiologically help defecation and continence. Unlike advanced stage (stage IV) hemorrhoids, which require surgical intervention, various topical agents (gels, ointments, creams), oral venoactive drugs, homeopathic and phytotherapeutic products and nutritional supplements are widely used in stage II and III hemorrhoidal disease. The genus Ruscus (family Asparagaceae) is a group of plants native to the Mediterranean basin, Southern and Western Europe, and Iran, represented by perennial, rhizome-based, and evergreen shrubs. Among the species belonging to this genus, Ruscus aculeatus L. has the widest distribution area. The subsoil parts of the Ruscus plant are rich in steroidal saponins and show vasoconstrictor, diuretic, anti-inflammatory and venotonic effects, especially with ruscogenin and neoruscogenin compounds. Due to these properties, R. aculeatus stands out as a traditional phytotherapy agent that has been used for a long time in chronic venous insufficiency. However, there are no controlled clinical studies in the literature evaluating the efficacy and safety of Ruscus aculeatus L. in hemorrhoidal disease. Therefore, this study was aimed to systematically evaluate the contribution of a phytotherapeutic product containing R. aculeatus to the treatment of stage II-III hemorrhoidal patients and to provide scientific evidence of a new and potentially safe herbal treatment option that can be used in the treatment of hemorrhoids.
