Libido

200mg/kg of a lysophilized extract of the roots of dactylorhiza hatagirea for 28 days is able to enhance male rat attraction towards females (2.5-fold) and was able to modify mount latency (36% reduction) and post-ejaculatory latency (36%) in a manner suggesting libido enhancement.^[1]

There is an increase in the penile erection index seen with 100mg/kg of dactylorhiza hatagirea(defatted water extract) daily for two weeks to rats, although this was less than the benefit seen withCurculigo orchioides and Chlorophytum borivilianum.^[2] This has been noted elsewhere with 200mg/kg of the root water extract over 28 days.^[1]

Appears to have libido enhance properties, and when compared against other ayuvedic herbs on the penile erection index it appeared to be less potent
