Anecdotal evidence vs. clinical evidence

It seems that every sexual enhancement supplement -- and most nutritional products in general -- seem to be advertised as having been “clinically tested,” while others are identified as backed just by anecdotal evidence.

Which factor should hold more weight when evaluating a product’s potential? One would think that a product tested in clinical studies is reliable, but then again, what about the traditional forms of medicine that have been passed down from generation to generation? Don’t those count?

Take the natural extract of Eurycoma Longifolia, which can be found in a capsule-based supplement called AchieviMAX, for instance. Said to be found in abundance in Malaysia, Singapore and neighboring countries, this ingredient can boost testosterone levels -- or so says traditional wisdom based on anecdotes.

Does it matter to anyone if this ingredient hasn’t passed clinical trials with flying colors? Or maybe men would rather go for formulas comprised of more familiar and well-documented, all-natural sexual stimulants like Yohimbe and Tribulus Terrestris.
