A recent study in the journal Circulation found that flavonoids in dark chocolate improve circulation. That could be good for erection problems that are due to poor circulation. Flavonoids are naturally-occurring antioxidants that protect plants from toxins and help repair cell damage. Studies show that flavonoids and other antioxidants have similar effects on people. They may help lower blood pressure and decrease cholesterol, both of which are factors that contribute to erectile dysfunction.
Erectile dysfunction (ED) is defined as the persistent inability to attain and maintain an erection that is sufficient to permit satisfactory sexual performance (1). The current pharmaco-therapeutic research in ED focuses on underlying endothelial dysfunction as the root cause for ED and introduction of phosphodiesterase type 5 inhibitors to potentiate nitric oxide (NO) action and cavernosal smooth muscle vasodilation, has revolutionized modern ED treatment over the past two decades (2). In contrast to Western Medicine, the traditional and complementary medicine (TCM) aims at restoration and better overall bodily regulation with medicine to invigorate qi (energy) in vital organs such as kidney, spleen and liver; to enhance physical fitness, increase sexual drive, stabilize the mind and improve the overall situation resulting in natural and harmonious sexual life (3).
