This calls for serious conservation strategies of plant targets in drug development borrowing from the indigenous knowledge of the local people. For instance, medicinal plants documented in this study like Warburgia ugandensis and Cirtopsis articulata used in erectile dysfunction and sexual impotence and ED need to be conserved based on their demand and medicinal value to the people. In the event of increased biotechnology and the use of modified living organisms in agriculture, health and environment, most people will go for natural products18,26. Furthermore, research in natural products is on the increase in both developed and developing nations to show that there is renewed interest in medicines of natural origin.
"Just because there is evidence doesn't mean it's good evidence," says Andrew McCullough, MD, associate professor of clinical urology at New York University Langone Medical Center in New York City, and one of the original clinical investigators for the ED drug Viagra (sildenafil). "And before men with ED start down the naturopathic route, it's smart to make sure that there isn't some underlying medical condition that needs to be corrected." Moreover, it is estimated that 30 million American men have erectile dysfunction, and 70% of cases are a result of a potentially deadly condition like atherosclerosis, kidney disease, vascular disease, neurological disease, or diabetes. Additionally, ED can also be caused by certain medications, surgical injury, and psychological problems.

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.
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.
"The problem with alternative treatments for any medical problem, including erectile dysfunction, is that until you have about 20 well-controlled studies over several years, you really don't know what you are working with," cautions Richard Harris, MD, a urologist at Gottlieb Memorial Hospital, part of the Loyola University Health System in Chicago.
Yohimbe (Pausinystalia yohimbe): again an Asian favorite which originates from an evergreen tree native to the West African Countries of Congo, Cameroon and Gabon, it is the only herb listed in the Physician’s Index Reference as supporting sexual function. Its Latin name is Pausinystalia yohimbe. The USA FDA approved yohimbe as the first plant derived drug for treating impotency long ago and was dubbed the herbal viagra II in the February 1999 edition of Environmental Nutrition. Alkaloid in yohimbe i.e., Iso Yohimbine, allo-yohimbine, yohimbinine, yohimbane, yohimbenine and corynantheine blocks alpha-2 adrenergic activity allowing vasodilation. It also acts as a monoamine oxidase inhibitor increasing serotonin in the brain. Yohimbine has a dual aphrodisiac function: it improves sexual function (10) by displacing epinephrine from alpha-2 adrenergic receptors in the pelvic area and it increases proneness to arousal thru supplying the epinephrine from the alpha-2 receptors to the central nervous system (brain) where it is active as a neurotransmitter. Side effects include nervousness, anxiety, insomnia, and possibly mild hypertension (5).
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)
Wild oats: a study in 1986 by the Institute for Advanced Study of Sexuality in San Francisco reported effects like heightened sexual awareness, increased sexual thoughts, more orgasms (36% in men and 29% in women) and some male subjects showed increased levels of testosterone attributed to unbinding of testosterone from TBG. Oats supply steroidal saponins which modulate hormonal balance (5).
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.
Classically the neuro-physiology of ejaculation traces the 3 Phases in which ejaculation is a complex event involving the (I) the propulsion of sperm and seminal plasma into the prostatic urethra which is accompanied by (II) bladder neck closure and (III) coordinated contractions of the bulbocavernosus and ischiocavernosus muscles, striated muscles of the pelvic floor, lower limbs and trunk. In the Asian Society of the Aging Male Study  63% have reduced erection, 68% reduced or absent ejaculation and 19% pain or discomfort at ejaculation. Disorders of ejaculation can be due to: (I) disorders of production of sperm or seminal plasma/prostatic secretions (II) disorders of propulsion. In the case of anejaculation (absence of ejaculatory) which is the ultimate disorder of ejaculation, the causes can be best classified as (I) primary or secondary. After covering psychogenic causes of ejaculation failure, the organic causes due to non-dynamic and obstructive etiologies in the prepubertal and post pubertal male will be highlighted. More details will be given on retarded ejaculation, premature ejaculation, aspermia, painful and weak (poor propulsive force) ejaculation. The evaluation of the patient must include a detailed history taken from the patient and often his partner. Aside from haematologic tests, various forms of radiological and ultrasonic imaging, neurophysiologic studies may be required. For the general practitioner the commonest scenario will be in the ED Clinic with abundant men with performance anxiety presenting with premature ejaculation. In the male aging clinic lack of arousal is the commonest cause of retarded orgasm and ejaculation but this group is plagued by decreased touch sensitivity, the need for more direct stimulation, reduced drive to orgasm, a less intense orgasm, ejaculation being weaker and of reduced quantity and disturbing complaints of a longer recovery period and less number of attainable orgasms per day or week. Thus it is not mere rumor that “by the time a man reaches 55, the refractory period to ‘do it again for a man’ increases to 12 hours or even up to a week”. In the STD clinic, painful or bloody ejaculation is frequently seen. The Condom may cause condom retarded orgasm/ejaculation.
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.
Penile implants - are generally used if physical damage (like an accident) makes the anatomical parts needed for an erection not work. These are inserted by surgery and can provide a permanent treatment choice if others fail to work. The implants can be semi-rigid or inflatable. They can be pretty expensive and are not usually available on the NHS.
From the researchers' point of view, the usage of herbal remedies in managing male sexual disorders is useful because of long cultural history of utilisation and the current renewed interest in natural products to sustain health globally. As a way recognising the values and roles of traditional medical knowledge in health care provision, further research into the efficacy and safety of herbal remedies in male sexual disorders is precious in Uganda and beyond. More so, the establishment of rapport between relevant government department in Ministry of Health, modern health workers through collaborative and networking ventures with traditional healers under close supervision and monitoring of herbal treatments is noble.
Historically, it has been shown that herbal medicines may cure or prevent certain ailments. However, there are very little recorded data available to support the dose, efficacy, side effects and interactions. Because the safety and efficacy of herbal remedies have not been assessed, unlike synthetic drugs, well-controlled and randomized studies are warranted to establish the therapeutic efficy and safety of such products. Determination of side effects and interactions with prescription medicines are also needed. The amount of active ingredients in herbals may vary among preparations; thus, standardization of herbal medicines is required.
Some natural viagra supplements have been shown to increase nitric oxide levels and increase blood flow to the penis. But there are no true natural alternatives to prescription ED medication, like Viagra. But healthy food and (some) vitamins and supplements can improve your overall health and blood flow. And anything that improves blood flow can treat some of the causes of erectile dysfunction (as well as making you healthier).
