“…Curculigo orchioides (Kali Musli) is claimed to enhance sexual behavior and erection in male rats (Chauhan, Rao, & Dixit, 2007). The African tropical plant Microdesmis keayana has also shown increased sexual arousal and erectile function in rats treated with its alkaloid extracts (Zamble, Sahpaz, Brunet, & Bailleul, 2008;Zamble et al, 2009). The tropical legume Mucuna pruriens (velvet bean), the Indonesian flowering plant Eurycoma longifolia Jack (Tongkat Ali), and the Asian flowering plant Ferula harmonis (Zallouh Root) have also showed similar effects on male rats as the studies discussed above (Ang & Sim, 1997;Suresh, Prithiviraj, & Prakash, 2009;Zanoli et al, 2005).…”
