Although CNN focused the episode on maca, I think there are more potent natural aphrodisiacs such as catuaba, muira puama, tribulus terrestris, mucuna pruriens, tongkat ali, horny goat weed and yohimbe, just to name a few. See

   A year ago an Italian team at Morgagni-Pierantoni Hospital, in Forlì, Italy, did a double-blind clinical trial on fifty men affected by mild impotence. They were randomised to treatment with maca extract, 2.4 grams, or placebo. After 12 weeks patients taking maca experienced a more significant increase in sexual satisfaction than those taking placebo.

   Two years ago researchers at the Department of Psychiatry, Massachusetts General Hospital, in Boston, tried to find out if maca was effective in those who were taking selective-serotonin reuptake inhibitors since SSRI meds induce sexual dysfunction in many patients. SSRIs included Prozac, Zoloft, Paxil, and other prescription antidepressants. They tried 1.5 g/day and 3 g/day in twenty depressed outpatients. Those taking 3 grams a day had a significant sexual improvement but subjects on 1.5 g/day did not notice as much.

   Comments: Maca is sold in varying dosages and extracts. We have had the best responses in those who have alternated its use with other herbal aphrodisiacs, such as in the Natural Sex Boosters package mentioned above. See also
