This is another herb used for centuries in Chinese medicine to treat erectile dysfunction and low libido. A study from 2008 found  that the herb blocks the effects of an enzyme that restricts blood flow to the penis. Researchers believe horny goat weed, also known as epimedium, acts as a natural phosphodiesterase inhibitor, the same action as seen in erectile dysfunction drugs such as Viagra or Cialis. However, the research indicated that horny goat weed can work more effectively and cause fewer side effects than the drugs.
In addition, this amino acid increases sperm volume and makes sperm quality better. Moreover, L-Arginine is most effective for men with initially low NO levels. Thus, this amino acid normalizes endothelial nitric oxide synthesis. That contributes to the vascular function restoration, including penile vascular function. The amino acid prevents aging changes in the blood vessels and dramatically reduces the harmful effects of nicotine on arteries with capillaries.

Move a muscle, but we're not talking about your biceps. A strong pelvic floor enhances rigidity during erections and helps keep blood from leaving the penis by pressing on a key vein. In a British trial, three months of twice-daily sets of Kegel exercises (which strengthen these muscles), combined with biofeedback and advice on lifestyle changes — quitting smoking, losing weight, limiting alcohol — worked far better than just advice on lifestyle changes.
However, you might actually be better off going one step back in the chain reaction and taking an L-citrulline supplement. While your body converts L-arginine to nitric oxide, it also metabolizes it too fast when the amino acid is taken in an oral supplement, according to a 2011 study from the University of Foggia in Italy. L-citrulline, which the body converts to L-arginine, is actually a better option to follow the same metabolic pathway and serve as a treatment for ED, the same study found.
Acupuncture. Acupuncture has been used for centuries to treat ED and impotence in China. A recent review of studies on acupuncture for erectile dysfunction was published in the British Journal of Urology International. After reviewing four studies, the authors concluded that there was not sufficient evidence to say that acupuncture worked. However, some experts believe it's worth trying. "Acupuncture can work," says Gilbert. "It probably works best to treat the psychological component of ED. There is very little downside to trying it."
Ginseng. Korean red ginseng has long been used to stimulate male sexual function, but few studies have tried systematically to confirm its benefits. In one 2002 study involving 45 men with significant ED, the herb helped alleviate symptoms of erectile dysfunction and brought "enhanced penile tip rigidity." Experts aren't sure how ginseng might work, though it's thought to promote nitric oxide synthesis. "I would recommend ginseng [for men with ED]," says Espinosa. Discuss with your doctor before taking it since ginseng can interact with drugs you may already be taking and cause allergic reactions.
Prescription drugs called “oral phosphodiesterase-5 (PDE5) inhibitors” are considered the “first-line non-invasive treatment” options for patients with ED. These include the drugs that go by brand names: Sildenafil, Vardenafil or Tadalafil. They work by helping the smooth muscle cells lining the blood vessels that supply the penis with blood to work properly. This allows a man to maintain an erection more easily.
Those men that took 3gm of the root daily for 8 solid weeks are said to have improvement in their sexual intercourse frequently when compared to those that did not take it. As Maca is very safe generally, research shows that it increased the blood pressure in the user that have cardiovascular disease that took 0.6 gm of the root daily. Therefore, it is highly suggested that your daily intake must be less than 1 g/kg or 1g/2.2 pounds.
Aggressive and excessive sexual behaviour is most common cause of ED. Males practicing self-stimulation, coition, or gaining erections without ejaculation few times in a day suffer with problems like ED due to exhausted reproductive system. Tufan herbal ED pills provide natural erectile dysfunction treatment by handling effects of these practices as well. These are regarded as the best ED pills as these not only protect a male from ill-effects of these issues but also reverse their effects to improve health and energy levels of male reproductive system.
Although there are few men who are born absolutely impotent, the number of men with erectile problems are many especially those tending to 50 years and above. Pfizer28 reported that about 40% of men above years, 50% of men above 50 years, 60% of men above 60 years and in any population are affected by ED. ED has profound effect on psychological well being, it can be devastating, it can lead to low self-esteem, depression, negative effect on relationships and reduced life satisfaction28. Among several other causes, aging is one of the factors leading to ED. There are some other social causes of ED such as high unemployment rates, and diseases like diabetes, hypertension, HIV/AIDS, high cholesterol levels, stress, smoking and obesity28. ED is slowly creating adverse problems in homes in Uganda and particularly, among the mid-aged and old men. The men with sexual impotence and erectile dysfunction deserve proper diagnosis of the conditions and treatment. Thus, the plant remedies described may be healthy if administered
Gingko biloba: this is an example of a tonic herb that equilibrates our body systems. When tired it energizes and when stressed it relaxes the individual. It increases blood circulation which better prepares the male for the heart-racing excitement of sex. Early reference to its medicinal use was in 2900 BC Chinese Materia medica which believed it increased sexual energy. Gingko’s circulation enhancer called terpene lactone increases cerebral as well as genital blood flow and its significantly increased production of dopamine, adrenaline and other neurotransmitters in the brain improves pleasure arousal and alertness (5).

There’s no bedroom bummer quite like having to fly at half mast, but your penis problems are likely more common than you think: As many as 30 million American men suffer from erectile dysfunction, and one in four who seek treatment for ED are actually under the age of 40, according to a study in The Journal of Sexual Medicine. We all know there’s a little blue pill that can fix the failure to launch—but you don’t necessarily have to fill a ‘script to save your stiffy.
Yohimbine: The main component of an African tree bark, yohimbine is probably one of the most problematic of all natural remedies for ED. Some research suggests that yohimbine can improve a type of sexual dysfunction that is linked with a drug used to treat depression. However, studies have linked yohimbine to a number of side effects, which can include anxiety, increased blood pressure, and a fast, irregular heartbeat. Like all natural remedies, yohimbine should only be used after advice and under supervision from a doctor.
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.
