Despite the name, horny goat weed actually helps improve your erection, not libido.  Botanically known as epimedium, this herb has been used by the Chinese for centuries to treat, among other things, low libido and erectile dysfunction. “A growing body of research shows that isolated icariin—the extract of epimedium—inhibits the enzyme phosphodiesterase-5 (PDE-5) and significantly increases nitric oxide synthase, helping to improve erectile function,” says Fisch. In fact, this is the same mechanism that Viagra works through (but the herb comes with a way better name).
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)
Between 2001–2006, one-third of the US population had insufficient amounts of vitamin D, according to the Institute of Medicine. Risk factors for vitamin D deficiency include obesity and high BMI, not enough sun exposure or outdoor activity, having darker skin and suffering from certain from inflammatory conditions like Crohn’s disease. You can get a blood test to find out if you’re vitamin D deficient.
Older age. A man’s risk increases past the age of 40, as age is the variable most strongly associated with impotence. This is due to changing hormones, higher risk for heart problems and those affecting circulation, and decreased sexual desire that often occurs with increasing age. For example, based on findings from the National Health and Social Life Survey, it’s been found that “men between 50–60 years old are more than 3 times as likely to experience erection problems and to report low sexual desire compared to men aged 18 to 29 years.” (3)
Arginine. The amino acid L-arginine, which occurs naturally in food, boosts the body's production of nitric oxide, a compound that facilitates erections by dilating blood vessels in the penis. Studies examining L-arginine's effectiveness against impotence have yielded mixed results. A 1999 trial published in the online journal BJU International found that high doses of L-arginine can help improve sexual function, but only in men with abnormal nitric oxide metabolism, such as that associated with cardiovascular disease. In another study, published in 2003 in the Journal of Sex & Marital Therapy, Bulgarian scientists reported that ED sufferers who took L-arginine along with the pine extract pycnogenol saw major improvements in sexual function with no side effects. Arginine can be helpful, says Geo Espinosa, ND, director of the Integrative Urological Center at NYU Langone Medical Center. Espinosa says that men with known cardiovascular problems should take it only with a doctor's supervision; L-arginine can interact with some medications.

The field visits and excursions were arranged with the healers for places far from their homesteads or took place concurrently with the interviews and discussions. When going to the forests, game reserves or other areas where herbalists collect plant specimens, prior arrangements were made with the community leaders and park staff. This was done with individuals or groups depending on where the herbs are collected. In the shared areas such as the fishing villages, or the multiple use areas, group and individual excursions were conducted. Some of the medicinal plants that are harvested from distant places such as the Democratic Republic of Congo, other districts and unsafe areas within the reserve were not collected but their local names were recorded. The data collected were to supplement the information on plant names, plant parts used, collection of the herbarium voucher specimens and conservation status of these medicinal plants. The medicinal plants collected were given the voucher numbers and then later identified in Botany Department herbarium of Makerere University.

Muira puama (Ptychopetalum olacoides): although used in Asia, this potency wood is actually the best known Amazonian folk medicine which increases libido and penile hardness. It acts as a nerve stimulant to heighten receptiveness to sexual stimuli as well as physical sensation of sex (9). Rich in sterols e.g., sitosterol, campesterol and lupol it activates the body’s receptors for hormones like testosterone to heighten libido and enhance performance (5). Also present are volatile oils like champor which helps restore sex drive and inner depth of libido and mental ability to be aroused.
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.
DHEA. DHEA, or dehydroepiandrosterone, is a natural hormone that the body uses to make the male hormone testosterone. DHEA and testosterone decrease with age, just as ED increases with age, so it seems that taking DHEA might protect against ED. But Harris says that "it is unlikely that taking DHEA would raise your testosterone enough to make much difference." DHEA should not be used by people with liver problems; it also has many side effects.

L-arginine is used by the body to increase and precursor to the production of human growth hormone, prolactin and several amino acids It even increases our sensitivity to insulin, analogously to body when we exercise, by accepting more glucose to enter into our cells and improve better cellular energy therefore less fatigue with much more stamina. L-arginine’s function in supporting our metabolic health are also extremely important for building stronger muscle tissue and potentially to help fight inflammation.
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.
Cordyceps (Dongchongxiacao): this Chinese caterpillar fungus and the carcass of the larvae of various insects are collected in the period of the Summer Solstice (tenth solar term). They are cleaned and dried in the sun or baked and used for treating deficient kidneys manifested as impotence, seminal emissions and soreness and pain in the lower back and knees (17). Cordyceps (Dongchongxiacao) is used with Dogwood fruit (Shanzhuyu), Dioscorea (Shanyao) and Dadder seed (Tusizi). The herb can also be used alone.
Oyster meat: totally natural, oyster extract is excellent for men’s reproductive health and endurance. It is a rich source for the amino acid taurine, which is used for cardiac health and nerve transmission. Historically known as an aphrodisiac, flavonoids in oyster meat have been shown to stimulate the reproductive system. However, still its potency is under question (5).

L-arginine. L-arginine is an important amino acid that the body needs to build proteins. Because L-arginine has been shown to improve blood flow, some alternative practitioners have recommended that the supplements be used to treat ED. The Natural Medicines Comprehensive Database, which is a reliable authority on alternative medicines, says L-arginine is possibly effective for treating erectile dysfunction. But Harris warns that "although this supplement could improve blood flow, side effects can be dangerous." L-arginine can cause an allergic reaction or worsen asthma in some people; it can also lower blood pressure.

The neurovascular mechanism of erection is complex and involves multiple factors including hormones, neurotransmitters, elements of the autonomic nervous system (sympathetic and parasympathetic) and vasodilators such as NO. The common causes of ED include psychogenic disturbance with failure to relax cavernous smooth muscle, arterial insufficiency as a result of atheromatous disease, damage to the parasympathetic nervous system, spinal cord injury, diabetes or following pelvic surgery such as radical prostatectomy, radical cystectomy or bowel resection [4]. It is important to note that cavernous nerves are unique in that although they belong to the autonomic nerves system they do not release either acetylcholine (Ach) or norepinephrine; however, they release NO in the penis. NO relaxes the smooth muscle of the corpora cavernosa via cyclic GMP (cGMP), allowing expansion of the cavernosal lacunar spaces, blood flow and erection. Thus, NO is not a direct dilator of the smooth muscle of cavernosal bodies, but it is an important mediator in this process. Erectile function may also be adversely affected by cigarette smoking, excess alcohol consumption, obesity and systemic diseases such as mononucleosis, hepatitis, HIV and cancer. Some men are prone to develop an erection that fails to subside after ejaculation (ie, priapism). The condition is associated with sickle-cell disease and leukemia, or may be a result of intracavernosal injection of drugs such as prostaglandin E1 [4]. Peyronie’s disease causes a physical bend in the erect penis and also contributes to ED.
L-arginine, an amino acid that is naturally present in the body and helps make nitric oxide, supports a successful erection. Nitric oxide is responsible for making the blood vessels relax, which helps sustain an erection for men. A 1999 study, observed the effects of six weeks of high-dose (5 grams/day) orally administered nitric oxide (NO) donor L-arginine on men with organic ED. Thirty-one percent of those who took 5 grams/day of L-arginine experienced significant improvements in sexual function. Burns told Medical Daily, “l-arginine and deer antler velvet” have been the most popular go-to natural treatments for men.
Many products contain undocumented “fillers” that can cause allergic reactions.  In recent years, the FDA has found over 300 herbal products that contain hidden, deceptively labeled, or dangerous ingredients4. And since 2015, the FDA has released public warnings on more than 160 ED supplements and “male enhancement” products found to contain dangerous ingredients and contaminants5 .   An independent study of FDA data, conducted in 2018, found almost 800 herbal supplements that contained unlisted ingredients6.
The art of acupuncture has become the new treatment for everything from back pain, depression, and even ED. Impotence could be more of a state of mind, and acupuncture may help. Through this alternative therapy, fine needles are placed in various parts of the body to relieve pain or stress. Although there are many mixed studies for acupuncture and ED, many tend to confirm positive results. A 1999 study found acupuncture improved the quality of erection and even restored sexual activity in 39 percent of participants.
