“…Indeed, an anabolic and androgenic activity of the Bulbine natalenis stem extract could be demonstrated in male Wistar rats (Yakubu & Afolayan, 2010). Furthermore, extracts of Serenoa repens (fruit), Pygeum africanum (¼ Prunus africana) (cortex), Urtica dioica (radix) (Farag et al 2013), Secale cereale (pollen), Hypoxis rooperi (¼ Hypoxis hemerocallidea) (herba), and Cucurbita pepo (semen) were studied regarding their potential to cure benign prostate hyperplasia (Oelke et al, 2009). in vitro activities could mainly be documented for the inhibition of 5α-reductase and growth factors.…”
