Damiana, a shrub from the US, particularly from Texas, acts directly on the central nervous system with a relaxing effect. This relaxing effect translates into immediate benefits on sexual performance both from the point of view of erective capacity and from that of the duration of sexual intercourse, as, in most cases in which these problems manifest themselves it is possible to find among the causes that generate the same a strong psychological component. The use of the Damina should be seen from an integrative perspective, thus taking the same for long and regular periods of time.
