This study was an open label safety and efficacy study. Each subject received a specific dose of a formulation containing Kaempferia parviflora. There would be attempted telephone or e-mail contact in 2 weeks following enrollment.

Participants would undergo assessments of blood tests, vital signs, body weight with completion of questionnaires.

The primary objective was to assess the effect of Kaempferia parviflora on erectile function among overall healthy males age 50 to 70.
