A , Internal Medicine, answered. Ginkgo biloba comes from the leaves and seeds of the Chinese ginkgo tree. Some people believe that this botanical actually boosts sexual desire and treats erectile dysfunction (ED). Does this herb work to help ED? The jury is still out. Many studies find no benefit from ginkgo biloba for ED. And when you buy a natural dietary supplement with gingko, youâre never really sure how much gingko the pill contains. Even if the pills genuinely contain ginkgo biloba, the quality and potency can vary greatly.
