There are a zillion OTC herbal erection aid products. Some of them are effective for some men. Everybody's reaction tends to be different. Often there are undesirable side effects. If you're thinking of trying anything, read the label carefully to see what the ingredients are, and then do some internet research as to the side effects. Most of these products contain a whole bunch of different herbal ingredients. Two herbal ingredients to be cautious about are yohimbe and mucuna pruriens, both of which can boost your blood pressure to a potentially dangerous level. The best thing to do when trying something that you've never taken before is to take a very small dose first, and make sure that it doesn't do anything bad to you. If you live to tell about it, then try a larger dose and see if does what it's supposed to do.
