Ginkgo biloba. Known primarily as a treatment for cognitive decline, ginkgo has also been used to treat erectile dysfunction -- especially cases caused by the use of certain antidepressant medications. But the evidence isn't very convincing. One 1998 study published in the Journal of Sex & Marital Therapy found that it did work. But a more rigorous study, published in Human Pharmacology in 2002, failed to replicate this finding. "Ginkgo has come out of fashion in the past few years," says Ronald Tamler, MD, assistant professor of medicine and codirector of the men's health program at Mount Sinai Medical Center in New York City. "That's because it doesn't do much. I can say that in my practice, I have not seen ginkgo work -- ever."
Erectile dysfunction (ED) is defined as the “inability to reach and maintain erection during the intercourse” (1) leading to the victim’s experience of inadequate libido, inefficient orgasm and retarded or premature ejaculation. In Recent times, ED has been labeled as the most common sexual problem among pleasure-seeking males and a complaint of all men irrespective of their age, race and culture but age is the most important risk factor for ED (2). It is reported that nearly 100 million people around the world are living with erectile dysfunction. Yet, only 10% of these 100 million, i.e., 10 million are opting for treatment, despite enormous advancements and treatment facilities in all parts of the world (2). To cite a few countries, in China and Korea only 9% and 30% males voluntarily admit to having ED (2) and in most of the other countries in Asia, it is still considered very sensitive with considerable social stigma and secretly will resort to herbal remedies and tonics before seeking conventional medical help.
Nitric oxide is made internally from L-arginine, which is an amino acid found in red meat, poultry, fish, and dairy products. In other words, L-arginine is the building block for nitric oxide, which is essential for erections. A lack of one can lead to a lack of the other. However, there’s a problem when it comes to treating L-arginine deficiency with supplements.
Erectile dysfunction can occur as a side effect of medication taken for another health condition. Common culprits are high blood pressure meds, antidepressants, some diuretics, beta-blockers, heart medication, cholesterol meds, antipsychotic drugs, hormone drugs, corticosteroids, chemotherapy, and medication for male pattern baldness, among others.
The causes of ED are varies from one individual to another. For whatever cause, since an erection requires a precise sequence of events, ED can occur when any of the events is disrupted. This sequence includes nerve impulses in the brain, spinal column, and area around the penis, and response in muscles, fibrous tissues, veins, and arteries in and near the corpora cavernosa23. Thus, ED causes reported include, damage to nerves, arteries, smooth muscles, and fibrous tissues. These are often as a result of diseases, such as diabetes, kidney disease, chronic alcoholism, multiple sclerosis, atherosclerosis, vascular disease, and neurologic diseases that account for about 70 percent of ED cases23. NIH23 reported that between 35 and 50 percent of men with diabetes experience ED. NIH23 further reported that the usage of many common medicines such as blood pressure drugs, antihistamines, antidepressants, tranquilizers, appetite suppressants, and cimetidine (an ulcer drug) can produce ED as a side effect. Nevertheless, psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure cause 10 to 20 percent of ED cases. In addition, men with a physical cause for ED frequently experience the same sort of psychological reactions (stress, anxiety, guilt, depression)23. Other possible causes are smoking, which affects blood flow in veins and arteries, and hormonal abnormalities, such as not enough testosterone23.
With wide-ranging action, ginseng (Panax ginseng), also called Asian ginseng, has been shown in human studies to have an anti-stress effect; improve physical and mental performance, memory, and reaction time; and to enhance mood. Ginseng increases physical working capacity in humans in many ways, including by stimulating the central nervous system, and regulating blood pressure and glucose levels. A 2015 study found that active constituents in ginseng had significant benefit for ED in men with diabetes.
Saw palmetto. Saw palmetto comes from the fruit of a small palm tree. It has been used to treat symptoms in men with an enlarged prostate gland, such as difficulty urinating, and it has been recommended to treat ED caused by an enlarged prostate. However, several recent clinical trials did not show that saw palmetto works any better on an enlarged prostate than a placebo does. "There is no evidence that saw palmetto should be used to treat erectile dysfunction," says Dr. Gilbert. Like ginkgo biloba, saw palmetto can interact with some prescription medications.
The Plant: A low-growing flowering annual that’s originally from southern Europe but is now an invasive weed in parts of the United States and Australia. The plant’s common names, like puncturevine or devil’s thorns, tells you exactly why most people hate it: it drops sharp, spiny seed pods that lie in wait for unsuspecting victims to step on them. It’s also toxic to grazing livestock like sheep.
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.
Yohimbine is the principal alkaloid of the bark of the West African evergreen P johimbe (formerly known as C johimbe), family Rubiaceae. The main active chemical present in P johimbe bark is yohimbine hydrochloride (an indole alkaloid), which has stimulant and aphrodisiac effects. However, the levels of yohimbine that are present in P johimbe bark extract are variable and often very low. Therefore, although P johimbe bark has traditionally been used to treat ED , there is insufficient scientific evidence to form a definitive conclusion in this area. It is an antagonist of α2-receptors and has no direct relation to erection. It acts as a sex motivation stimulant. Yohimbine has been used as both an over-the-counter dietary supplement in the form of an herbal extract, and as a prescription medicine in purified form for the treatment of sexual dysfunction. Yohimbine 20 mg or adjusted dose has been found to be effective in the treatment of orgasmic dysfunction. Yohimbine was recently associated as a treatment for type 2 diabetes mellitus in animal and human models carrying polymorphisms of the alpha-2A adrenergic receptor gene . The National Institutes of Health states that yohimbine hydrochloride is the standardized form of yohimbine that is available as a prescription medicine in the United States, and has been shown in human studies to be effective in the treatment of male impotence. Yohimbine hydrochloride USP has been used to treat ED. Controlled studies suggest that it is not always an effective treatment for impotence, and evidence of increased sex drive (libido) is anecdotal only. It cannot be excluded that orally administered yohimbine can have a beneficial effect in some patients with ED. The conflicting results available may be attributed to differences in drug design, patient selection and definition of positive response. Yohimbine has been shown to be effective in the reversal of sexual satiety and exhaustion in male rats, and has also been shown to increase the volume of ejaculated semen in dogs, with the effect lasting at least 5 h after administration. Yohimbine has also been shown to be effective in the treatment of orgasmic dysfunction in men, and has also been used for the treatment of sexual side effects caused by some antidepressants, and female hyposexual disorder. Yohimbine has significant side effects, such as anxiety reactions. Higher doses of oral yohimbine may create numerous side effects, such as rapid heart rate, high blood pressure, overstimulation, insomnia and/or sleeplessness. More serious adverse effects may include seizures and renal failure. Yohimbine should not be consumed by individuals with liver, kidney or heart disease, or psychological disorders. The therapeutic index of yohimbine is low; the range between an effective dose and a dangerous dose is very narrow. Side effects include gastrointestinal upset, increased blood pressure, headache, agitation, rash, tachycardia and frequent urination .
The estimated range of men worldwide suffering from ED is from 15 million to 30 million23. According to the National Ambulatory Medical Care Survey (NAMCS), for every 1,000 men in the United States, 7.7 physician office visits were made for ED in 1985. By 1999, that rate had nearly tripled to 22.3. This is in USA, where statistics are clearly compiled, the level of awareness and education is high as compared to sub Saharan countries like Uganda. This is a clear indication that there are many silent men, particularly couples affected by ED.
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.

If you have symptoms of ED, it’s important to check with your doctor before trying any treatments on your own. This is because ED can be a sign of other health problems. For instance, heart disease or high cholesterol could cause ED symptoms. With a diagnosis, your doctor could recommend a number of steps that would likely improve both your heart health and your ED. These steps include lowering your cholesterol, reducing your weight, or taking medications to unclog your blood vessels.
