The vitamin-deficiency disease pellagra was first identified in 1735 by Spanish physician Gaspar Casal. Considered to be Spain’s first epidemiologist, Casal is famous for his clarity and independence of thought, along with his conceptual change in the approach to medicine. Instead of mere observation and reporting, Casal moved to a fact-based induction methodology, presaging the work of John Stuart Mill, the political philosopher, economist, and logician, one hundred years earlier.
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).

Often when we start to look outside of mainstream medicine for alternative protocols to heal our health issues we replace one pill-taking protocol with another. The prescription drugs are replaced with a long list of supplements. Supplements alone, without any other lifestyle changes, will have some impact, but it will be nowhere near what they can achieve when working in a body supported with a healthy way of life.

Testosterone levels generally decrease as an individual ages. This is normal and natural, but it can lead to erectile problems for some people because androgenic hormones such as testosterone play an important part in regulating the function of tissues in the penis and testicles. One study found that supplementing with testosterone gel improved both the libido and erectile function of participants with low testosterone between the ages of 32 and 84.
In the New World, maize was traditionally treated with lime, an alkali now shown to make niacin nutritionally available and thereby reducing the chance of developing pellagra.1 However, when in the 18th century corn cultivation was adopted worldwide, treatment with lime was not accepted because the benefit was not understood. Thus in the New World, often heavily dependent on corn, cultivators rarely suffered from pellagra, which became common only when corn became a staple that was eaten without the traditional treatment. Of interest, if maize is not so processed, it is a poor source of tryptophan as well as niacin.
E.D. may just be that early warning sign. Erections depend on blood flow, and blood flow depends on nice, wide-open arteries. Atherosclerosis doesn’t just affect the arteries around your heart; if you have plaque build-up, you are likely to have it all around the arterial system — and the penile artery is one of the smallest arteries you have (no matter what you claim about your size). So if you have atherosclerosis, then the plaque there will be one of the first places where you would notice a decline in blood flow.

It’s important to talk to a medical professional about ED, in order to determine the cause of the issue before exploring treatment options. That said, erectile dysfunction has been found in recent years to be a symptom of zinc deficiency.
