Yohimbine is an indole alkaloid derived from the bark of the African yohimbe tree (33). Yohimbine has been noted to treat fatigue, depression, diabetes, and sexual dysfunction. A meta-analysis of seven placebo-controlled trials (34) deemed yohimbine superior to placebo for the treatment of ED with rare adverse events. The proposed mechanism of action (35) is via the inhibition of central alpha-2-adrenergic receptors, decreasing central inhibition of arousal, and increasing penile nerve stimulation resulting in increased NO. Common side effects include headache, sweating, agitation, hypertension and insomnia. Contraindications include patients on tricyclic antidepressants, anti-hypertensives and central nervous system stimulants.

If you’ve been to the health food store lately, you’ve seen shelves lined with vitamins and “organic” supplements, each claiming to boost immunity, revitalize organ function, or “promote health.” And it’s working. Supplements are currently a $30 billion industry in the US, with more than 90,000 products on the market, and vitamin use is on the rise. In fact, a recent survey in Journal of American Medicine Association showed that “52% of US adults reported use of at least 1 supplement product.”
There’s a reason chocolate became a gift given before amorous activity. Cacao increases levels of the mood-boosting hormone serotonin, which can lower stress levels, boosting desire and making it easier to reach orgasm. And that’s not all: Cocoa also increases blood flow through the arteries and relaxes blood vessels, sending blood to all the right regions, which can boost pleasure.
Spice up your love life with chillies. When your face flushes after eating a curry, that’s the blood vessels expanding thanks to the effect of the chillies. And it’s not just the blood vessels in your face that get the boost. Biologically speaking a hard-on is simple hydraulics – more liquid (blood) being forced into little tubes (blood vessels) in your penis – so what you need is a strong heart and smooth, healthy pipework.
The fowl most associated with belt-loosening feasts is lean, high in protein and the single best food source of arginine, the amino acid. Researchers at the NYU School of Medicine gave L-arginine to a group of impotent men, and found that six out of 15 men receiving the amino acid claimed an improved ability to achieve erections, while none of the 15 men in the placebo group reported any benefit. Additionally, the bird is rich in DHA omega-3 acids, which have been shown to boost brain function, improve your mood and turn off fat genes, actually preventing fat cells from growing! Just make sure you buy white meat only, as dark contains too much fat. And steer clear of prepackaged, sliced lunchmeat—those turkeys are strictly jive.
During sexual stimulation, sexual thoughts, or nocturnal erections, the neurotransmitter nitric oxide (NO) is released from the endothelial cells and the parasympathetic nerve terminal causing relaxation of two cylinder-like muscles called the corpora carvenosum. Nitric oxide influences an increase in concentrations of cyclic guanosine monophosphate (cGMP), which after numerous pathways triggers smooth muscle relaxation, and simultaneous closing of small veins traps blood in the cavernosal muscles, keeping blood in the cavernosal tissues that cause and maintain an erection.

Intensive lifestyle changes that include a Mediterranean type diet, circuit-type resistance training, with 15- to 60-second rest between sessions has shown to improve erectile score in a randomized trial. Men in the intervention group had a significant decrease in glucose, insulin, low-density lipoprotein cholesterol, triglycerides, and blood pressure, and a substantial increase in HDL cholesterol.15


10 ways of knowing that you are properly squeezing your pelvic floor muscles (PFM): 1) The base of your penis retracts inwards towards the pubic bone as you contract your PFM. 2) The testes rise towards the groin as you contract your PFM. 3) When you place your index and middle fingers in the midline between the scrotum and anus you feel these muscles tighten as you contract your PFM. 4) You can pucker your anus (not the gluteal muscles) as you contract your PFM. You feel the anus tighten and pull up and in, known as “anal wink.” 5) You get the same feeling as you do when you are ejaculating when you contract your PFM. 6) When you touch your erect penis, you feel the erectile cylinders surge with blood as you contract your PFM. 7) You can make your erect penis elevate (lift and point) as you contract your PFM. 8) You can stop your urinary stream completely when you contract your PFM. 9) You can push out the last few drops of urine that remain after completing urination when you contract your PFM. 10) After pursuing PFM training, you notice improvements in erectile rigidity and durability as well as better quality ejaculations, ejaculatory control and improvement in urinary control.

While ED may seem like a monumental problem on its own, it is usually a sign of a bigger health issue. It is important to isolate and address underlying issues and support overall health by cleaning up your diet, maintaining healthy blood sugar balance, quitting smoking, regularly moving your body, and managing stress appropriately. Along with these healthy lifestyle changes, a carefully chosen natural supplement routine can offer additional support so you can regain your vitality and get on with enjoying your life.
For obvious reasons, ED can be a sensitive subject, one that until relatively recently men were more likely to try to hide than to deal with. Fortunately, a deeper understanding of the variety of causes of erectile dysfunction has led to medications, therapies, and other treatments that can be more individualized and more likely to be effective—and more open discussion about addressing the concern.
A variety of personal habits and lifestyle choices have been linked to ED. In some ways, this is a good thing, since habits can be broken and choices reconsidered. What's more, many of the lifestyle factors that contribute to sexual problems are ones that affect overall health and well-being, both physical and mental. Addressing these factors, therefore, can have benefits beyond improving erectile dysfunction.
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.

With drug therapy, there’s a risk of side effects such as headaches, back pain or an upset stomach. Before taking any medication for erectile dysfunction it is important to ensure your doctor is ok with that decision. Medication may not work for all men, for instance, if you have diabetes or have previously had prostate surgery. ED medication might also have serious risks if you’re currently taking nitrates (commonly prescribed for chest pain), have heart disease or have low blood pressure.22

Talking to a counsellor or therapist can help some people overcome erectile dysfunction related to these problems, possibly for good. They can also help you if your erectile dysfunction is causing you stress, as this can make matters worse.

Ginseng is the most common ingredient among top-selling supplements for men’s sexual health (36). The English word ginseng derives from the Chinese term renshen. Ren means “person” and shen means “plant root”. This plant has been named in this manner as its roots resemble the lower limbs of a human, Traditionally, ginseng has been used to restore and enhance the normal well-being of the body. The effects are due to ginseng’s reactions with the central nervous system, metabolism, immune function and cardiovascular system. The principal active compounds are triterpene saponins known as ginsenosides. Animal studies have suggested that specific ginsenosides may be responsible for ginseng-mediated effects on copulatory behavior (37). Ginsenoside induces smooth muscle relaxation by hyperpolarizing the smooth muscle membrane via activation of large-conductance KCa channels (38).

In a 2005 study, three months of twice-daily sets of kegel exercises combined with biofeedback and advice on lifestyle changes, such as quitting smoking, losing weight, and limiting alcohol, worked far better than just giving the participants advice. “Wearing tight pants will affect impotence along with some other medical conditions like diabetes and heart disease,” which can also affect a man’s degree of impotence, Dr. Jennifer Burns, specializing in family practice with an emphasis on gastrointestinal health at the BienEtre Center, told Medical Daily.
Acupuncture. Though acupuncture has been used to treat male sexual problems for centuries, the scientific evidence to support its use for erectile dysfunction is equivocal at best. In 2009, South Korean scientists conducted a systematic review of studies on acupuncture for ED. They found major design flaws in all of the studies, concluding that "the evidence is insufficient to suggest that acupuncture is an effective intervention for treating ED."
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.
