A 2011 study of 160 men with moderate or severe erectile dysfunction divided the group in two—80 men were given niacin supplements, and 80 a placebo. The group given niacin reported improved ability to “maintain an erection versus the control group.” It’s not exhaustive research, but still promising. The best part about niacin is that it’s naturally found in foods like turkey, avocado, and peanuts (yum). If you’re not a turkey sandwich fan, you can supplement with a vitamin B complex.
Ginkgo biloba may increase blood flow to the penis. Researchers discovered the effect of gingko on ED when male participants in a memory enhancement study reported improved erections. Another trial saw improvement in sexual function in 76 percent of the men who were on antidepressant medication. This is why researchers believe that ginkgo may be effective for men who are experiencing ED due to medication.
There’s no bedroom bummer quite like having to fly at half mast, but your penis problems are likely more common than you think: As many as 30 million American men suffer from erectile dysfunction, and one in four who seek treatment for ED are actually under the age of 40, according to a study in The Journal of Sexual Medicine. We all know there’s a little blue pill that can fix the failure to launch—but you don’t necessarily have to fill a ‘script to save your stiffy.

The Science: Some studies have implied that feeding maca to domestic cattle increases sperm production, but there is very little data about any sexual effect on humans. One very small randomized double-bind trial of men with erectile dysfunction found that men taking maca extract reported a small increase in their ability to get erections. But so did the control group. As with the fenugreek study, a similar study with a larger group of people is needed to see whether any differences between the controls and the maca-eaters are real.
Pumpkin seed: besides having a pleasant flavor, pumpkin seeds are revered by the Chinese for its antidepressant properties (5). More importantly, pumpkin seed ingestion can impact prostate health, which is very important for male sexual health. It is commonly used to strengthen the prostate gland and promote healthy hormone function in men. Myosin, an amino acid found in pumpkin seeds, is known to be essential for muscular contractions.
Deer antlers (Cervi pantotrichum): the most popular of sexual tonics. In the Chinese medical teaching, kidneys control sexual function; hence foods and herbs such as this can invigorate impotency and infertility increasing semen production as well (5). Best quality are from young bucks with new horn still in velvet with blood visible in the cartilage.
Most importantly, herbal supplements are not well regulated in the United States.  Studies have shown that 40-50% of herbal supplements do not even contain the supposed main ingredient, and many contain substances that are not listed which may have dangerous side effects2.  Another study found that over two thirds of the products tested had substituted other plant species for the plants listed on the label, and a third of products also contained other fillers or contaminants3.  A study by the New York State Attorney General of herbal products sold at GNC, Target, Walgreens, and Walmart found that four out of every five products didn’t contain the ingredient they claimed!  Fourteen US states and territories have petitioned Congress to regulate the herbal supplements industry.
Ginseng is generally indicated for daily, consistent use in moderate doses. Do not use ginseng as a short-term stimulant. Ginseng and other adaptogens work best after long-term (one–three months) use by regulating hormone levels and other biological functions to protect us against the damaging effects of chronic stress,” says herbalist Christopher Hobbs, author of The Ginsengs. A typical dose is 4,000–6,000 mg per day.

Yohimbine: The main component of an African tree bark, yohimbine is probably one of the most problematic of all natural remedies for ED. Some research suggests that yohimbine can improve a type of sexual dysfunction that is linked with a drug used to treat depression. However, studies have linked yohimbine to a number of side effects, which can include anxiety, increased blood pressure, and a fast, irregular heartbeat. Like all natural remedies, yohimbine should only be used after advice and under supervision from a doctor.


Extracts from medicinal plants have been used for considerable period of time in many parts of the world, particularly in Southwest Asia, to treat ED [16]. The current review focuses on four botanical medicinal plants, the roots of which are used in enhancing sexual performance and in the treatment of ED: Eurycoma longifolia Jack (tongkat ali); Chlorophytum borivilianum (safed musli); Withania somnifera (ashwagandha); and Pausinystalia johimbe (yohimbine, formerly known as Corynanthe johimbe).

ED can also occur as a side effect of some medications, for example some high blood pressure medications such as certain diuretics and beta blockers. If you think that a medication you are taking has a negative effect on your sex life, you should discuss this with your prescribing doctor. Your doctor may be able to recommend an alternative treatment.


Conventional impotence treatments typically involve the use of medications which work with the body's natural chemistry in order to promote the ability to have an erection. Oral medications such as Viagra, Levitra and Cialis are commonly prescribed; injectable medications such as the impotence drug Caverject are also used for treating male impotence.
Phytolacca dodecandra leaves and roots are pounded and smeared on ripe banana and then the ripe banana roasted before being eaten for treating erectile dysfunction. However, care has to be taken Phytolacca dodecandra is poisonous. Cola acuminata fruits are mixed with other plants in Benin to treat primary and secondary sterility24. Cola acuminata is also said to be diuretic and laxative when administered orally24. Some Acacia species are regarded as aphrodisiacs in Niger2. Cassia species have high repute as drugs and poisons. For instance, Cassia sieberiana is used urinary problems, impotence and kidney diseases in Mali24. In Burkina Faso, Cassia occidentalis is used as a stimulant24. Flueggea virosa is famous medicine in African cultures. Flueggea virosa used in sterility, aphrodisiacs, stimulant, rheumatism, arthritis, spermatorrhoea, kidney and liver problems among many other diseases treated17,24.

Red Ginseng — One small randomized trial found evidence that red ginseng may offer modest improvements in ED symptoms (as compared with placebo). A meta-anaylsis published in the British Journal of Clinical Pharmacology states, “Traditionally red ginseng has been used to restore and enhance normal well-being, and is often referred to as an adaptogenic….Possible mechanisms of action of red ginseng include hormonal effects similar to those of testosterone. Others have postulated that red ginseng might induce relaxation of the smooth muscles.”  (5)
Yohimbine. This chemical is found in the bark of an African tree called yohimbe. It has been used as a male aphrodisiac in Africa, and under medical supervision it has been used as a prescription drug to treat ED. Supplements made from yohimbe bark are also available without a prescription, but they can be life-threatening if used at high doses, according to the Natural Medicines Comprehensive Database. The supplement can interact in a harmful way with certain drugs, such as blood pressure medications, and should be avoided by anyone with liver, kidney, heart, or diabetes problems or problems with anxiety or depression. Like DHEA, yohimbine should not be taken without a doctor's supervision.

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.

Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.


DHEA. Testosterone is essential for a healthy libido and normal sexual function, and erectile dysfunction sufferers known to have low testosterone improve when placed on prescription testosterone replacement therapy. Similarly, studies have shown that taking over-the-counter supplements containing DHEA, a hormone that the body converts to testosterone and estrogen, can help alleviate some cases of ED. But DHEA can cause problems, including suppression of pituitary function, acne, hair loss and its long-term safety is unknown, says McCullough. For this reason, many experts discourage use of the supplements.
The Claim: If you squint and have an excellent imagination, mature ginseng roots vaguely resemble a human body. That ties into folk ideas for finding medicines–in this case, the idea that a plant that looks like a person must contain materials that help sick people. Ginseng was traditionally used as a tonic to treat erectile dysfunction and low sexual drive in men (as well as many other complaints).

Uses and risks of viagra Viagra treats erectile dysfunction and pulmonary arterial hypertension. For sexual purposes, it helps someone with erectile dysfunction achieve and maintain an erection. However, Viagra can have unpleasant side effects, and an overdose can be serious. We cover everything you need to know about Viagra in this article. Read now
Catuaba (Erythroxylum catuaba): in Brazil, Catuaba Extract is considered to be a central nervous system stimulant (5), without the side effects of caffeine. This is used in some Asian remedies for sexual weakness and lowered libido. European herbalists have found that Catuaba may have aphrodisiac properties and can be used to combat sexual weakness.
When it comes to boosting sexual performance, many men will walk all over God’s green earth looking for ways to maintain a good sex life. Luckily men, all you have to do is walk — not run — 2 miles a day. This, along with other healthier lifestyle interventions can help obese men reduce their risk of ED, or even “reverse” current impotence, according to a 2005 study. This comes of importance, since maintaining a trim waistline is a good defense for ED, as men with a 42-inch waist are 50 percent more likely to have ED than those with a 32-inch waist. Getting to a healthy weight and maintaining it is a good strategy for preventing and treating ED.
Eleuthero, a distant relative of Panax ginseng, has been used in Chinese medicine for 2,000 years. Eleuthero, also called Siberian ginseng, has been shown to enhance physical performance in several studies. Research shows it has antioxidant, immune-boosting, and cholesterol-lowering properties. A study in the Journal of Ethnopharmacology concludes that the active constituents, eleutherosides, alleviate both physical and mental fatigue.

“Obecalp” is “placebo” spelled backwards. It might help – treatment with inactive placebos (inert substances used in evaluation of new drug treatments) works about one-third of the time in scientific studies when patients don’t know they’re getting a fake drug. Placebos are generally safe since they contain no known active agent. (However, I personally never give patients inactive placebos, and many physicians regard them as unethical.)
Erectile dysfunction supplements and other natural remedies have long been used in Chinese, African and other cultures. But unlike prescription medications for erectile dysfunction, such as sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis, Adcirca) and avanafil (Stendra), erectile dysfunction herbs and supplements haven't been well-studied or tested. Some can cause side effects or interact with other medications. And the amount of the active ingredient can vary greatly from product to product.
