Avena sativa is an extract from wild oats straw, and a rather recent entry to the field of aphrodisacs. While oats have a long reputation of being the most energizing grain, the alleged sexual effects have not commonly been recognized in previous centuries. Avena sativa is said to free bound testosterone in both men and women. If this was indeed the case, a prosexual effect would be obvious. Most positive effects of testosterone, including sex drive, are attributed to free testosterone, while bound testosterone is mainly a subject of study when enlarged prostates are the primary concern.
