The seeds are also a rich source polyunsaturated fatty acids shown to boost prostaglandins — hormone-like substances that play a key role in feeling turned on.

According to the FDA (Food and Drug Administration), many of these products sold on the internet contain potentially harmful compounds. And they aren’t listed on the label. In an investigation, the FDA found that one-third of these online supplements were laced with undisclosed ingredients. This includes sildenafil—the active ingredient in Viagra. Doctors prescribe Viagra to some patients, but it’s not safe for everyone. The drug could interact with other medications and lower your blood pressure to dangerous levels. This makes ordering supplements online risky. You don’t know whether they contain sildenafil or other ingredients that could harm your health. 
For centuries, men have tried all sorts of natural remedies for erectile dysfunction (ED) -- the repeated inability to get or maintain an erection firm enough for sexual intercourse. But do they really work? It is simply not scientifically known at this point. Furthermore, you take these remedies at your own risk, because their safety profiles have not been established. What follows are commentaries by experts and reviews in the field of alternative treatments that are available over the counter for erectile dysfunction and impotence.
Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject Impulse, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include papaverine, alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).
Ginseng, specifically “red ginseng,” is known as the “herbal Viagra” that helps puts to rest men’s bedroom woes. Red ginseng is when the root has been steamed and then dried. The ginseng root is the part of the plant that is mostly used as a natural remedy when in its supplement form. However, the plant must be grown for a minimum of five years before it can be used. In a 2008 review, seven studies on red ginseng and ED, ranging in dosages from 600 to 1,000 milligrams three times a day, were found to provide evidence for the effectiveness of the herb in ED treatment.

Men can judge themselves pretty harshly when it comes to their performance in between the sheets. The unsettling fear of not being able to rise to the occasion becomes a reccurring nightmare for men that is often equated with failure, loss of dignity, and masculinity. If you suffer from erectile dysfunction (ED), don’t be so hard on yourself, since impotence can almost always be improved with treatment, without having to rely on Viagra or other medications. Whether you suffer from ED, or hope to prevent the condition, here are six tips to overcome impotence without the side effects of the little blue pill.

Double down on the marinara to protect your manhood. Men who eat over 10 servings of tomatoes each week have an 18 percent lower risk of developing prostate cancer — the result of lycopene, an antioxidant which fights off toxins that can cause DNA and cell damage — a study in the journal Cancer Epidemiology, Biomarkers and Prevention found. A previous study found the garden vegetable could also improve sperm morphology (shape); men with the highest tomato intake contributed to between 8 and 10 percent more ‘normal’ sperm.
A 2000 study conducted at the Institute of Sexology in (where else?) Paris found that muira puama, a Brazilian shrub traditionally used in South African folk medicine as an aphrodisiac, increased libido in a majority of men who complained of impotence and a lack of desire. Other studies show this happy-making herb also counteracts chronic stress, depression and nervous exhaustion.
Deer velvet is a covering found on the growing bone and cartilage of deer’s antlers. In Eastern medicine, deer velvet is sought after for its Chinese medicinal properties which include boosting one’s endurance and improving one’s immunity. People have also used deer velvet as an aphrodisiac or to treat ED. The randomized double-blind placebo-controlled study on deer velvet by Conaglen et al. (31), no benefit but this study was underpowered involving healthy participants with no sexual dysfunction.
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 brew is rich in compounds called catechins, which have been shown to blast away belly fat and speed the liver’s capacity for turning fat into energy. But that’s not all: Catechins also boost desire by promoting blood flow to your nether region. “Catechins kill off free radicals that damage and inflame blood vessels, increasing their ability to transport blood,” says Cassie Bjork, RD, LD of Healthy Simple Life. “Catechins also cause blood vessel cells to release nitric oxide, which increases the size of the blood vessels, leading to improved blood flow,” she explains. Blood flow to the genitals = feeling of excitement, so sipping the stuff will, well, make you want to get it on. Bjork suggests drinking four cups a day to feel the full effects.

It hits where it hurts the most – your member. Erectile dysfunction or ED is a spoiler in bed and can shatter your ego irreparably. ED, also called impotence, is the inability of a man to achieve and maintain an erection sufficient to permit satisfactory sexual intercourse.1 Men who cannot get or maintain an erection that lasts long enough or is rigid enough to complete sexual intercourse are considered to have erectile dysfunction.
Spice up your love life with chillies. When your face flushes after eating a curry, that’s the blood vessels expanding thanks to the effect of the chillies. And it’s not just the blood vessels in your face that get the boost. Biologically speaking a hard-on is simple hydraulics – more liquid (blood) being forced into little tubes (blood vessels) in your penis – so what you need is a strong heart and smooth, healthy pipework.
For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact.
