Be wary of 'herbal Viagra'

After the medication Viagra was introduced in the late '90s, it quickly gained a reputation as an effective treatment for the condition. A number of nonprescription products claiming to be "herbal Viagra" soon followed. Many of these products contain unknown quantities of potent ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug that should be given by prescription only. Although the Food and Drug Administration has banned several of these products, including Viril-Ity-Power (VIP) Tabs, V.Max and Rhino Max, a number of other potentially dangerous erectile dysfunction remedies remain on the market.
