The medical ethnobotanical indigenous knowledge were collected by visiting traditional healers and documenting the medicinal plants used and other socio-cultural aspects allied with sexual impotence and erectile dysfunction. The methods used to collect the relevant information regarding the medicinal plants used included informal and formal discussions, field visits and focused semi-structured interviews.
A cold slice of watermelon can do more than just satisfy thirst and hunger during the warm summer months; it can help with bedroom satisfaction. Citrulline, the amino acid found in high concentrations of watermelon, is found to improve blood flow to the penis. A 2011 study revealed men who suffered from mild to moderate ED and took L-citrulline supplementation showed an improvement with their erectile function and were very satisfied. Natural watermelon juice, or “nature’s Viagra,” can also be easier on the stomach, since taking pills like Viagra can cause nausea and diarrhea.

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.


And just because you’re using a “natural” herb doesn’t mean you won’t feel any side effects. Ginseng can cause hypoglycemia or bleeding in some people, and at high doses puncturevine can damage the kidneys. Plus, the FDA has found that a lot of supplement companies make sure their erection-enhancing products actually produce erections by tossing in some Viagra off-label. If you really need it, it’s probably better–and safer–to go see your doctor for a prescription.
Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones. 
Animal testicles: derived from bulls and wild boars, the orchic substance has been used as a way to possibly increase testosterone levels and sperm counts. In Singapore, testis soap was once very popular (Figure 2). It is still sold in parts of China and Japan. The dried Dog testis and penis (canis familiaris) is believed to tonify the kidneys and strengthen the yang II. Kidney deficiency is believed to be the cause of impotency in Chinese literature.
A combination of yohimbine and L-arginine is shown to significantly improve erectile function in people with ED. L-arginine is an amino acid that helps expand blood vessels. It’s regarded as safe and effective for ED but can cause side effects like nausea, diarrhea, and stomach cramps. Avoid taking L-arginine with Viagra, nitrates, or any high blood pressure medications.
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.
Having your current medication checked – if you are taking medication already, it could be that your erection problems are a side effect. Have a doctor check whether this is the cause of your problems and if it is, you might be able to switch medications and then find that your erectile dysfunction goes away completely – or at least improves. Medications that can cause erection problems include:
Ginseng is the root of some Araliaceae plants, which grows in northeast China. Ginseng is the number one herb in TCM that is used to maintain the balance of the body and enhance the vital Qi energy. ED is said to be caused by Qi deficiencies in the Kidney and Liver and Ginseng helps to improve Qi flow to these organs, especially when used with acupuncture. It has been confirmed clinically to enhance erectile function. The ginsenosides are the main active components in ginseng that give it anti-inflammation, anti-tumor, antioxidant, as well as apoptosis inhibition and preventing the degeneration of neurons in dorsal penile nerves while reducing the oxidative stress in the corpus cavernosum. 1
Doing physical activities regularly boosts blood supply and improves your heart. This helps blood flow to all corners of the body, including the blood flow leading to the firm erections. Exercising also steps up your libido by releasing endorphins that make you feel good. Additionally, exercise produces nitric oxide that keeps the arteries open. Therefore, the flow of blood to the penis becomes speedier. Start with brisk walking at least 20 minutes a day or another activity to make more nitric oxide contributing to the maintenance of the erection and your health in general.
As per Massachusetts Male Aging Study, it is stated that 50% of male population is experiencing this erectile dysfunction at some point in their lifetime, especially at the age of 40 or above. However, men who are suffering from this problem unable to talk about it and suffer in silence, as it leads to low self-esteem, depression and guilty feeling.
The semi-structured interviews and discussions were held with the specialist resource users and other knowledgeable people on particular ailments by use of interview schedules for each respondent. Interviewed people were mainly the herbalists (both men and women) and TBAs. In this selection to some extent, ethnic groups were recorded where possible because different people use the same plants differently. The time and place of interviews were arranged according to the schedules of the respondent. Depending on where the interviews and discussions were held, recording was done immediately or afterwards or appointments were made for more details in a more convenient place arranged with the respondent. Key informants were identified and later interviewed separately and even followed for further details. Some of the key questions asked included, name of the respondents, the village or parish or sub-county he or she was coming from, diseases treated, plant local names used, parts harvested, methods of preparation and administration. In addition, ingredients and incantations with which the plants are used for preparation and where the herbal medicines were harvested were documented.
Gecko (Gejie): this toad-headed lizard (Gekko gecko L.) is caught in summer. The internal organs are removed, and the eyes are cut and drained. Pieces of bamboo are used to fix the body, and then the gecko is baked and put in a dry place. It is used to treat Impotence due to kidney efficiency. Gecko (Gejie) is used with Ginseng (Renshen), Pilose antler (Lurong) and Epimedium (Yinyanghuo). It can be used alone for this treatment.
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.
Do it at home: Take a white onion, peel it off, crush and then fry in butter. This mixture can be taken daily with a spoon of honey, but make sure to consume this mixture when your stomach has been empty for at least two hours. This remedy helps to treat premature ejaculation, impotence and involuntary loss of semen during sleep or other times (known as spermatorrhea).

The Plant: It’s true, the name’s hilarious. But as it turns out, it’s not just one plant: supplement manufacturers might put any one of 15 different species from this genus of shade-loving perennials inside that pill. That’s important to keep in mind, because the types and amounts of biologically active molecules the plant contains can differ from species to species.
Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.
I found the process of ordering the medication very easy and the communication from your company was excellent. I also thank you most sincerely in respect the processing of my order, the delivery. and excellent manner in which my medication was packaged and sent to me. In addition my goods arrived in good condition and on the date as stated. All round an excellent service from Dr. ED for which I am very grateful and which I strongly recommend to everyone.
In modern medication of erectile dysfunction, the oral prescription medication of popular Viagra (Sildenafil) is effective, but in some men it is not compatible and Sildenafil works in less than 70% of men with various etiologies and has certain side effects23. The availability of Viagra has brought millions of couples to ED treatment. Oral testosterone can reduce ED in some men with low levels of natural testosterone, but it is often ineffective and may cause liver damage34. Other drugs such as Yohimbine, papaverine hydrochloride [used under careful medical supervision]5, phentolamine, and alprostadil (marketed as Caverject) widen blood vessels. However, this available modern medication for the ED in men is very expensive for most of the rural people in Ugandan and other developing countries. Yet, in traditional medicine, there are several medicinal plants that have been relied on for use in the treatment of ED. This ethnobotanical indigenous knowledge has not been earlier documented and scientifically validated for efficacy and safety, future drug discovery and development.
While the rationale behind why it would work is airtight, the research on arginine’s actual effect on erectile dysfunction is slim, points out Charles Walker, M.D., assistant professor of urology and cofounder of the Cardiovascular and Sexual Health clinic at Yale University. But given its solid safety profile, minimal side effects, and potential benefit on heart disease, it’s worth a try, he adds, especially when taken in conjunction with other herbs on this list, which studies have shown can be more effective.
Most sincere gratitude to the sponsors, Third World Organisation for Women in Sciences (TWOWS), NUFU Medicinal plants Project through Botany Department, Faculty of Science, Makerere University, UNESCO-MAB Young Scientist Research Award, 2000, Gender studies, Makerere University and WHO-Uganda. The Staff of Queen Elizabeth National Park, Field assistants, local leaders, the resource users and all respondents, particularly the TBAs and traditional healers in Bushenyi, Mbarara and Kasese Districts who provided the information.
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 
This is the vegetable root from Peru that meets the entire health benefits. If you can add this to your diet, you will surely see the difference. Maca is highly rich in iodine, amino acids, iron and magnesium. There are three types of Maca; black, red and yellow. The black one appears to get rid of stress as you boost your memory. Stress could cause ED.
Usually patients will try less invasive alternatives to treat impotence before opting for surgery. These alternatives may include supplements, herbs, lifestyle changes and even medications. In cases where other treatments do not work to resolve ED, surgery might be a last-resort option. Surgery involves implanting a penile prosthesis. This is a saline-filled silicone device or a malleable device. Although the likelihood of serious side effects is considered to be low, certain risks are associated with surgery to correct erectile dysfunction. These side effects may include: anesthetic risk, device infection, and device malfunction or mechanical failure. Some studies have found that five years following surgery around 10–20 percent of men experience device malfunction and failure. Infection rates are low. Around one percent of men who opt for this type of surgery get an infection.

If you bike a lot and have a very narrow saddle on your bicycle, consider switching to a "no-nose seat" which is wider at the back than a conventional saddle, allowing more of your weight to be distributed to the sitting bones. Make sure the seat is level or angled slightly downward and at a height that allows your knee to be just slightly bent at the bottom of the pedal cycle. Raising the handlebars on your bike so that you're sitting upright may also help.
Yohimbe. Before Viagra and the other prescription erectile dysfunction drugs became available, doctors sometimes prescribed a derivative of the herb yohimbe (yohimbine hydrochloride) to their patients suffering from ED. But experts say the medication is not particularly effective, and it can cause jitteriness and other problems. "It's not a great drug," says McCullough. "And I suspect the herb is not as potent as the pharmaceutical version." What's more, evidence shows that yohimbe is associated with high blood pressure, anxiety, headache, and other health problems. Experts discourage its use.
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.

In one study, men with a Vitamin D deficiency were nearly 33% more likely to have ED. But you don’t need that much sun exposure to get a healthy amount of Vitamin D. As little as 15–20 minutes a day is enough. Taking Vitamin D is a good idea, especially if you are over 65. Vitamin D can also help if you’re obese or dark-skinned (dark skin limits the amount of Vitamin D you naturally, produce)
