Older age. A man’s risk increases past the age of 40, as age is the variable most strongly associated with impotence. This is due to changing hormones, higher risk for heart problems and those affecting circulation, and decreased sexual desire that often occurs with increasing age. For example, based on findings from the National Health and Social Life Survey, it’s been found that “men between 50–60 years old are more than 3 times as likely to experience erection problems and to report low sexual desire compared to men aged 18 to 29 years.” (3)
Ashwagandha’s reputation as a sexual enhancement herb is supported by research. One animal study showed that extracts of ashwagandha increased production of sex hormones and sperm, presumably by exerting a testosterone-like effect. In another clinical trial, the herb (taken at a dose of 3 gm per day for 1 year) was given to healthy male adults 50–59 years of age. Among benefits noted: serum cholesterol levels decreased, gray hair was reduced, and a vast majority (over 70%) reported improvement in sexual performance.
Yohimbe (Pausinystalia yohimbe): again an Asian favorite which originates from an evergreen tree native to the West African Countries of Congo, Cameroon and Gabon, it is the only herb listed in the Physician’s Index Reference as supporting sexual function. Its Latin name is Pausinystalia yohimbe. The USA FDA approved yohimbe as the first plant derived drug for treating impotency long ago and was dubbed the herbal viagra II in the February 1999 edition of Environmental Nutrition. Alkaloid in yohimbe i.e., Iso Yohimbine, allo-yohimbine, yohimbinine, yohimbane, yohimbenine and corynantheine blocks alpha-2 adrenergic activity allowing vasodilation. It also acts as a monoamine oxidase inhibitor increasing serotonin in the brain. Yohimbine has a dual aphrodisiac function: it improves sexual function (10) by displacing epinephrine from alpha-2 adrenergic receptors in the pelvic area and it increases proneness to arousal thru supplying the epinephrine from the alpha-2 receptors to the central nervous system (brain) where it is active as a neurotransmitter. Side effects include nervousness, anxiety, insomnia, and possibly mild hypertension (5).

A number of nonprescription products claim to be herbal forms of Viagra. Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
