A daily dose of niacin improves erectile function, particularly in men with high cholesterol, according to a 2011 study in The Journal of Sexual Medicine. The vitamin helps increase blood flow and reduce inflammation—one of the underlying causes of both high cholesterol and erectile dysfunction. “Vitamin B3 is also used to make sex hormones and other important chemical-signal molecules,” says Fisch. Like many of the others on our list, this tablet is most powerful when taken in conjunction with others: A cocktail of propionyl, L-carnitine, L-arginine, and niacin taken for three months improved 40% of erections in a study from researchers at Sapienza University of Rome in Italy.
Historically, it has been shown that herbal medicines may cure or prevent certain ailments. However, there are very little recorded data available to support the dose, efficacy, side effects and interactions. Because the safety and efficacy of herbal remedies have not been assessed, unlike synthetic drugs, well-controlled and randomized studies are warranted to establish the therapeutic efficy and safety of such products. Determination of side effects and interactions with prescription medicines are also needed. The amount of active ingredients in herbals may vary among preparations; thus, standardization of herbal medicines is required.
While the rationale behind why it would work is airtight, the research on arginine’s actual effect on erectile dysfunction is slim, points out Charles Walker, M.D., assistant professor of urology and cofounder of the Cardiovascular and Sexual Health clinic at Yale University. But given its solid safety profile, minimal side effects, and potential benefit on heart disease, it’s worth a try, he adds, especially when taken in conjunction with other herbs on this list, which studies have shown can be more effective.
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).

Maca root (Lepedium meyenii W): this native Peruvian root has been cultivated for thousands of years. Considered an integral part of the diet, the Incans found maca root so potent (14), it was restricted to royal use only. Known for its energy enhancing abilities, maca root enjoys a special place amongst herbalists and health seekers. Like ginseng, this plant is employed to increase strength, libido and sexual function (14). Clinically its effects have been proved with experimental animals (5,15).
A list of 33 medicinal plants both cultivated and wild-harvested generated show that herbal remedies are greatly utilized by men for managing sexual impotence and erectile dysfunction in western Uganda. Erectile dysfunction and sexual impotence are old problem and traditionally the indigenous knowledge had ways of treating or managing these conditions associated with male reproductive system. These plants in the tables we are discussing have been in use for centuries in treating or managing conditions in male reproductive organs.
According to Uganda's health policy priorities8,25, men's reproductive health is not given any mention. The national health policy focuses on services like family planning, diseases control like STI/HIV/AIDS, malaria, perinatal and maternal conditions, tuberculosis, diarrhoeal diseases and acute lower respiratory tract infections that are given priority8,25. The sexual and reproductive health rights in Uganda focus on maternal and child mortality, family planning and the like exclusive of men's sexual needs and rights8.
Tribulus terrestris (6): this plant has long been used as a folk medicine in Eastern Europe and Bulgaria for sexual deficiency (5). The properties of this powerful ingredient have been associated with an increase in sperm production, sexual endurance, and testosterone levels. Also known as puncture vine, this herb has gained popularity over the past few years. Since testosterone plays a huge role for men, the addition of this herb can prove to be very beneficial. It is not a hormone as some believe. It is said that Tribulus terrestris can also help build muscle and strength, which enhances performance (5,7).
How common is impotence? According to findings from several studies, including “The Massachusetts Male Aging Study,” overall prevalence for men between 40–70 years old is around 52 percent (or around 30 percent of all men between 18–60 years old). That’s right — nearly half of all men over 40 experience erectile dysfunction symptoms at some point. Not surprisingly, research demonstrates that impotence is increasingly prevalent with age. Around 40 percent of men in their 40s experience sexual dysfunction. Up to 70 percent of men in their 70s experience ED. (1) Every year more than 617,000 new cases of impotence occur in the United States alone.
Do herbs work to rectify ED in the Aging Male? We will take some of these and discuss their properties. These herbals can be found throughout Asia and range from Eurycoma longifolia (Tongkat Ali), Ginseng and Tribulus etc. Those that act as Testosterone releasers have some value especially if the male has andropause and those containing some-pick-me-ups and energizers like Ginseng helps the tired and fatigued male and possibly those with asthenia. Deer horn contains growth factors and taking these do help improve nocturnal erections in the male with somatopause. Popular in historic Singapore was Penis soup and Snake meat (Figure 2), whilst Surabaya was known for Cobra meat and Cobra blood (Figure 3) which had claims of improving erectogenic prowess-the myths and realities concerning these and other Village doctor remedies are what they are—myths!
The medicinal plants used such as Citropsis articulata, Cannabis sativa, Cleome gynandra and Cola acuminata are frequently utilized. Some of these plants (Citropsis articulata, Cola acuminate) are already under sale for treating these conditions. Their propagation is on-going in western Uganda in places like Rukararwe Partnership Workshop for Rural Development Centre in Bushenyi District36 and researchers personal experience at Rukararwe. Rukararwe is a non-governmental organisation that is processing herbs, running a famous herbal clinic and with a medicinal plants arboretum and medicinal plants agro-forestry.
While these side effects mainly create discomfort, some individuals are at risk for more serious, even life-threatening reactions to these drugs. Some men have reported fainting after taking impotence medications, and priapism (a painful condition involving an erection that does not subside after more than four hours) has also occurred as an effect of impotence drugs. This condition can lead to permanent nerve damage; injectable drugs may also cause irreversible damage to the penis if used incorrectly.
Many stores sell herbal supplements and health foods that claim to have sexual potency and fewer side effects. They’re also often cheaper than prescribed medications. But these options have little scientific research to back up the claims, and there’s no uniform method on testing their effectiveness. Most results from human trials rely on self-evaluation, which can be subjective and difficult to interpret.
