The basis of ED herbal therapies is that they are anti-inflammatory, antioxidant and immunomodulatory, and can stimulate testosterone production. On the other hand, the synthetic drugs act via NO. The principal mediator of the relaxation of corporal smooth muscle of the penis has been shown to be NO, which is released mainly from parasympathetic nerves and endothelium . NO is believed to relax the corporal smooth muscle by activating soluble guanylate cyclase to increase cGMP content [14,15]. Penile rigidity depends on maximizing inflow of blood while minimizing outflow . The increased blood flow in the cavernous sinuses puts pressure on the walls of the surrounding veins, causing the lumen of the veins narrow, temporarily interfering with the flow of blood but causing tumescence. Normally, the parasympathetic nerve produces Ach. Ach acts on muscarinic receptors and nicotinic cholinergic receptors. When the parasympathetic nerve is stimulated, preganglionic neurons release Ach at the ganglion, which acts on nicotinic receptors on postganglionic receptors. Postganglionic neurons then release Ach to stimulate muscarinic receptors of the target organs. The muscarinic receptor M3, present in the endothelial cells and smooth muscle, is activated, and the M2 receptor in the heart may also be activated. This may result in the production of Ach, which can cause endothelial cells to produce NO. Ach released from postganglionic parasympathetic nerves acting through G-protein-mediated muscarinic receptors and nicotinic cholinergic receptors helps to release NO. Normally, M1, M2 and M3 receptors are found in secretory glands, heart, smooth muscle and endothelial cells, respectively. M1, M2 and M3 receptors cause activation of phospholipase C and generate inositol trisphosphate and diacylglycerol, which increase calcium. Activation of M4 may inhibit adenylate cyclase, decreasing the messenger cyclic AMP. This mechanism may be involved in the relaxation and contraction of cavernosal smooth muscle cells.
"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.
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).
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.
These three versatile herbs, used for centuries in Chinese and Ayurvedic medicine, have a variety of health benefits for both men and women. However, they work in several ways to address health issues of top concern to men, such as erectile dysfunction (ED) and high blood pressure, and I believe they should be a part of every man’s long-term plan for overall health.
Another important natural source of non-essential amino acid, L-Arginine is well studied to support many bodily functions even though its usually present in low quantities, especially as we started to age it is one of the most . One of the biggest benefits to our body is L-arginine or L Citruline (Our body converts L-citrulline to L-arginine, another type of amino acid) is converted into nitric oxide (proven), which causes blood vessels to open wider is its capability to improve blood flow and better circulation for Erectile Dysfunction.
There is no single cause for erectile dysfunction. Achieving an erection involves a complex series of physiological events; in order for an erection to occur, the body is required to coordinate nervous system responses with tactile sensations, emotional triggers, and signals from certain hormones. If any of these events are disrupted, impotence is likely to occur.
Pay attention to your vascular health. High blood pressure, high blood sugar, high cholesterol, and high triglycerides can all damage arteries in the heart (causing heart attack), in the brain (causing stroke), and leading to the penis (causing ED). An expanding waistline also contributes. Check with your doctor to find out whether your vascular system — and thus your heart, brain, and penis — is in good shape or needs a tune-up through lifestyle changes and, if necessary, medications.
Experts feel that treating erectile dysfunction on your own, without consulting a doctor, is unsafe. "If you have ED, the first thing you need is a diagnosis," says impotence expert Steven Lamm, MD, a New York City internist and the author of The Hardness Factor (Harper Collins) and other books on male sexual health. He says men with severe erectile dysfunction probably need one of the prescription ED drugs, which include Levitra (vardenafil) and Cialis (tadalafil) as well as Viagra. But, he says, mild ED -- including the feeling that "you're not as hard as you could be" -- often responds to natural remedies.
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.
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.
About 70 – 80% of the Ugandan population still rely on traditional healers for day-to-day health care. In some rural areas the percentage is around ninety compared to 80% reported world-wide10,13,14. WHO32 had earlier estimates that the usage of traditional medicine in developing countries is 80 %. This is an indication that herbal medicine is important in primary health care provision in Uganda. There are several reproductive ailments that local communities have been handling and treating for ages such as sexual impotence and erectile dysfunction (ED). The concept of reproductive health care has been focusing mainly on women disregarding men and yet men are part.
It doesn’t look good for the herbs. So far, there’s no data from controlled human trials that support the erection-promoting claims for any 5 of the most frequently used herbs. The icariin in the horny goat weed can help get it up, but since you’re getting the herb rather than a purified molecule, the concentration probably isn’t high enough to have much of an effect. Worse, it turns out that Viagra is much better at blocking that erection-killing enzyme than icariin is.
