Shape up. Because ED is often linked with restricted blood flow to the penis, keep your heart and arteries in good condition by maintaining a healthy weight, and following a diet high in fruits, vegetables and whole grains. Avoid saturated fats and trans fats. Regular aerobic exercise can improve blood flow to the genitals and reduce any stress that contributes to your ED.
L-arginine is an amino acid that is necessary for the lining of the blood vessels to produce nitric oxide. Nitric oxide allows the blood vessels to relax, thus improving blood flow throughout the body, including to the penis. Studies on L-arginine and erectile dysfunction have used between 2,000-5,000 mg a day in divided doses.ii Supplemental arginine is best taken on an empty stomach.3

This tasty green nut may be more than a great snack. A study published in the International Journal of Impotence Research examined how eating pistachios affected ED. Measurements were taken before men were put on a nut-heavy diet and after. Consuming pistachios for several weeks showed improvement in several parameters of ED, including improved International Index of Erectile Function scores for study participants.
Diaclina (also known as Panzer’s Darkling Beetle), Korean bug are used as aphrodisiacs in China, Korea and Southeast Asia. These are consumed either whole or as compounds within capsules. It is felt that the aphrodisiac properties come by stimulating the urogenital structures. Flies have been studied for their aphrodisiac effects, including Spanish fly, Chinese cantharide, and Eastern-Indian cantharide (32). The active compound found in the dried and mashed up bodies of these flies is cantharidin, which is a pheromone produced in the accessory glands of the male flies’ genitals. Cantharidin, stimulates the urogenital tract, causing pelvic hyperemia and possibly erections. As cantharidin is toxic and its safety dose not well determined, its use cannot be recommended. Cantharidin is lethal at high doses and exposure can lead to gastrointestinal and urogenital hemorrhage as well as acute renal failure.
In addition to being leaner and lower in calories than conventional cuts, grass-fed beef offers a host of benefits, from muscle-building to fat-burning to heart protection. You can add assistance in the bedroom to its list of good qualities; it’s an excellent source of Vitamin B12. A recent report from Harvard University highlighted a study that has linked low levels of B12 to erectile dysfunction. So, eat up! Bonus: It’s one of the healthy fats that actually makes you skinny.
While carrots have always been touted for their benefits for the eyes, studies reveal that carotenoids, vitamins, and minerals present in carrots act as antioxidants, anticarcinogens, and immune enhancers. Carrots also boast of antihypertensive, hepatoprotective, renoprotective, and wound healing benefits as well as cardio- and hepatoprotective, antibacterial, antifungal, anti-inflammatory, and analgesic effects. Studies on male rats have shown that carrots can exert an effect on fertility by elevating testosterone levels in them.10

Eastern medicine should be fully exploited, and integrated with modern medicine to combine the advantages of both TCM and Western medicine. More research should be conducted into the efficacy and safety of TCM, and integration of TCM and Western medicine may provide promising breakthroughs in future clinical treatment. This strategy may allow for the development of new therapeutic strategies based on concepts of TCM and integrated medicine. There is a need for multimodal therapy and holistic approach to treat men (and their partners) with ED through complementary use of herbal supplements and modern drug to optimize underlying medical comorbidities; acupuncture, exercise or massage to reduce stress and strengthen the body; introduction and escalation of various medical therapy with use of mechanical therapy to further enhance penile erection; and lastly surgical intervention in suboptimal or refractory ED cases.
Diseases like diabetes, cardiovascular disease, atherosclerosis, kidney disease, obesity, multiple sclerosis, and depression, and activities like bicycling, smoking, alcohol or drug abuse can impair blood flow or nerve impulses throughout the body. Surgery, as well as certain medications, can also result in ED. However, this may be a temporary problem.4
No matter what erectile dysfunction treatment or treatments (whether herbal remedies or not) a man ultimately decides upon, experts say it's important to eat healthily and to avoid smoking and heavy drinking. Moreover, adequate exercise, stress reduction, and sleep can improve erectile dysfunction in many. In addition, says Lamm, "A loving, receptive, and responsive partner is a home run. After all, this is still a couple's issue."
Besides mammalian organs, insects and arthropods are also consumed as aphrodisiacs in Eastern medicine. These include scorpions, spiders, beetles, flies and other bugs (32). Penile erections can be observed following administration of neurotoxins as it causes repetitive firing of the somatic, sympathetic and parasympathetic neurons, resulting in autonomic and neuromuscular over-excitation. Scorpions are often used as an ingredient found in herbal wines. However, there is a general lack of literature regarding the consumption of scorpion neurotoxins for potency.
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.

For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact.
