Erectile dysfunction (ED) or male impotence is defined as inability of a man to achieve or maintain penile erection sufficient for sexual activity. It is primarily a neuronal and endothelial dysfunction of the corpus cavernosum of penile tissue, and is partly characterized by reduced production of nitric oxide (NO). Other factors that may contribute to the pathogenesis of ED include androgen deficiency in aging men, hypertension, high cholesterol levels, atherosclerosis, diabetes mellitus, diseases of the prostate and heart, and anatomical deformity of the penis. ED may also be caused by some medications, prostate surgery and spinal cord injury. Psychological and social conditions such as stress, depression and unhappy marital relationship may contribute to the problem. Chronic infections and inflammation can also contribute to the disease process. ED is linked to an increased risk for cardiovascular diseases and stroke. Several orally active drugs (sildenafil, vardenafil, tadalafil, avanafil) are currently prescribed for treating ED to improve the arterial blood flow to the penile tissue. Medicinal plants and their extracts have been used in traditional medicine in southwest Asia and other countries to treat ED. The current review focuses on four medicinal plants that have been used as aphrodisiacs for enhancing sexual performance and for the treatment of ED. These plants include Eurycoma longifolia Jack (tongkat ali); Chlorophytum borivilianum (safed musli); Withania somnifera (ashwagandha); and Pausinystalia johimbe (formerly known as Corynanthe johimbe). Suggested mechanisms of action for each of the plant extracts will be discussed.
Poor eating contributes to the intake of excessive amounts of triglycerides, fat, glucose, and cholesterol. This leads to hypertension, insufficient HDL production, and lack of nitric oxide. As a result, sexual disabilities develop. They primarily manifest themselves as an inability to attain and sustain a firm, big, and long-lasting erection needed for a pleasurable sexual intercourse.
Cordyceps stem from Chinese traditional medicine and have been credited for everything from strengthening the immune system to increasing the male libido. These mushrooms are parasitic, growing on caterpillar larvae and killing the tiny insects from within. There has been some limited research into Cordyceps’ medical potential. One study published in the American Journal of Chinese Medicine found that these fungi boosted testosterone levels and sperm count in a sample of rats.
Tribulus Terrestris is the fruit of the Zygophyllaceae plant and it grows primarily in North China. It is a well-known aphrodisiac with records that trace back to ancient times. There are plenty of animal experiments that verify the effectiveness of Tribulus for improving erectile function. These effects are mostly due to its androgen enhancing ability, namely increasing testosterone levels. Though testosterone doesn’t directly cause an erection, it does play a role. Erection is made possible by many factors, but mostly it's through receptors on cells lining our arteries that stimulate a chain reaction that relaxes the blood vessels that go to the penis, allowing blood flow to get in. Low testosterone is often associated with overall poor metabolic and cardiovascular health. When the test is low, estrogen is usually high, leading to oxidative stress and calcification of the arteries, including the penis, restricting blood flow to the penis. So, improving testosterone levels, and improving overall metabolic function, while reducing oxidative stress is a good plan for improving overall sexual function and erection.
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.
E longifolia is a medicinal plant (family Simaroubaceae) native to Indonesia, Malaysia, Thailand, Vietnam and Laos. The root extract has been found to be the most powerful herbal aphrodisiac . Tongkat ali extracts contain many alkaloids, quassinoids, phenolic compounds, tannins, high-molecular-weight glycoproteins and mucopolysaccharides. The main bioactive compounds are eurycomaoside, eurycolactone, eurycomalactone, eurycomanone and pasakbumin-B. It is considered to be natural ‘Viagra’. It increases sexual desire, and enhances performance and general well-being [17- 19]. In addition to its aphrodisiac effect, other medicinal effects, such as antimalarial, antibacterial, antipyretic, antiulcer and antitumour effects, have been reported [20,21]. Root decoction has been used as a general tonic (18,22]. Laboratory animal studies show that root extract enhances sexual characteristics and performance in rodents [22-25]. In a study involving a boar model, it was found that E longifolia root extract-treated boars increased sperm counts and semen volume; the effect was attributed to increased level of plasma testosterone . Reports also suggest that E longifolia extract reverses the inhibitory effects of estrogen on testosterone production and spermatogenesis in rats . Oral administration of E longifolia extract to inexperienced castrated male rats produced dose-dependent increases in sexual performance . Zakaria et al  found that eurycomanone, a potential bioactive compound in the root extract of E longifolia, induced apoptosis in hepatocarcinoma (Hep G2) cells. Furthermore, their work suggested that eurycomanone was cytotoxic to Hep G2 cells and less toxic to normal Chang’s liver and WLR-68 cells. Tambi and Imran  investigated the effects of water-soluble extract of the root of E longifolia Jack and found that the extract increased semen volume, sperm concentration, percent of normal sperm morphology and sperm motility in male partners of subfertile couples with idiopathic infertility. Supplementation with E longifolia elevated the testosterone levels and upregulated osteoprotegerin gene expression in male Sprague-Dawley rats .
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.
Six herbs for treating erectile dysfunction Erectile dysfunction can be an embarrassing condition that can leave men unable to achieve an erection or a full orgasm. This MNT Knowledge Center article talks about six different herbal supplements that could help people with erectile dysfunction, including ginkgo biloba, horny goat weed, and red ginseng. Read now
The Science: There’s only been one double-blind placebo-controlled trial of the stuff: it found that men taking fenugreek extract reported that they felt more sexual arousal and experienced better orgasms. But testosterone levels in those same men didn’t change, and the study was also tiny–only 60 participants–so it’s not clear whether there’s actually a biochemical reason for the shift or whether it was all psychological. The experiment needs to be repeated with a larger group of people to find out whether those results can be reproduced.
Reproductive Health care is the second most prevalent health care problem on African continent4. Reproductive health care did not appear on the health agenda until recent after the Cairo conference on population and the Peking conference on women that it indeed became a live issue4. In some instances RH certainly includes the RH needs of the youth or adolescents.
Yohimbe A number of clinical trials have shown that the primary component of this bark from an African tree can improve sexual dysfunction associated with selective-serotonin reuptake inhibitors (SSRIs) used to treat depression. This herb has been linked to a number of side effects, including increased blood pressure, fast or irregular heartbeat, and anxiety. Yohimbe shouldn't be used without a doctor's supervision.
