Herbs: Saw Palmetto [Serenoa repens]; Ginkgo Biloba

Some traditional uses: 

Used to treat impotence, as well as low libido.  Reports suggest that results may be seen within days; increasing with consistent use. Also for symptoms of enlarged prostate.

Also suggested by studies done: Maca Root. We carry this in capsule form [You can find it on the Source Naturals page.]; it's one of the few herbs which doesn't take well to being tinctured.
