The seeds of tribulus terrestris are said to increase free testosteron and also i remember reading someplace that the seeds also contained the same alkaloid as sirian rue. Has anyone ever used it as a aphrodasiac or for it harmin content? Is it worth trying?
Here is a rather long thread (//http://forums.ayahuasca.com/phpbb/viewtopic.php?t=10646) over at the ayahuasca forums. I'd take some of the comments on MAOI with a grain of salt, but it is an interesting thread none-the-less.
