Please explain which food or herbal medicine could treat erectile dysfunction?

Food or herb?: There is no single food that can be consumed to treat erectile function. If there were, men would have consumed all of it by now. As for herbs, while many are advertised for ED, in the States, dietary supplement manufacturers can legally make miraculous claims w/o proof so buyer beware. Of note, the prescription drug yohimbine is derived from the over-the-counter African tree bark yohimbe.
