Cayenne: cayenne is also known as capsicum and plays a very large role in blood circulation. When cayenne is ingested, it acts to dilate blood vessels, allowing blood flow to increase to all areas of the body, especially major organs (5). The male penis benefits greatly from the ingestion of cayenne. It is a widely held belief that cayenne aids in longer lasting erections, with stronger ejaculations and more intense orgasms (5).
Ginseng (Figures 4,,55): this is an adaptogenic herb touted to have boosted the potency of Ottoman sultans. It increases the body’s ability to handle environmental stresses and combat biochemical imbalances. It energizes when one is fatigue and calms when overanxious. It also increases sex related hormones like testosterone and enhances sexual responses in men and women. It thus acts as a tonic, stimulant and aphrodisiac (4,5).
Muira puama (Ptychopetalum olacoides): although used in Asia, this potency wood is actually the best known Amazonian folk medicine which increases libido and penile hardness. It acts as a nerve stimulant to heighten receptiveness to sexual stimuli as well as physical sensation of sex (9). Rich in sterols e.g., sitosterol, campesterol and lupol it activates the body’s receptors for hormones like testosterone to heighten libido and enhance performance (5). Also present are volatile oils like champor which helps restore sex drive and inner depth of libido and mental ability to be aroused.
The Science: Male rats with damaged penile nerves had better erectile responses after they were given large doses of purified icariin, but as of yet no one has done the experiments to see whether the compound works in humans. Still, as far as the herb goes, it doesn’t really matter: horny goat weed doesn’t contain enough icariin to get even the smallest rise out of a rat.

Ginseng, specifically “red ginseng,” is known as the “herbal Viagra” that helps puts to rest men’s bedroom woes. Red ginseng is when the root has been steamed and then dried. The ginseng root is the part of the plant that is mostly used as a natural remedy when in its supplement form. However, the plant must be grown for a minimum of five years before it can be used. In a 2008 review, seven studies on red ginseng and ED, ranging in dosages from 600 to 1,000 milligrams three times a day, were found to provide evidence for the effectiveness of the herb in ED treatment.
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.
The Science: Chemicals inside these plants called ginsenosides are thought to ramp up the physiological pathway that makes nitric oxide, the neurotransmitter that gets the blood flowing during penile erection. Some studies support that idea: one found that ginsenoside-rich ginseng berry extracts relaxed smooth muscle inside rabbit erectile tissue. But so far there haven’t been high-quality double-blind and randomized trials of the chemicals’ effect on humans. The jury’s still out on whether ginsenosides have any effect on people at all, or (if they do) whether they work as well as medications like Viagra.

Erectile dysfunction (ED) is defined as the “inability to reach and maintain erection during the intercourse” (1) leading to the victim’s experience of inadequate libido, inefficient orgasm and retarded or premature ejaculation. In Recent times, ED has been labeled as the most common sexual problem among pleasure-seeking males and a complaint of all men irrespective of their age, race and culture but age is the most important risk factor for ED (2). It is reported that nearly 100 million people around the world are living with erectile dysfunction. Yet, only 10% of these 100 million, i.e., 10 million are opting for treatment, despite enormous advancements and treatment facilities in all parts of the world (2). To cite a few countries, in China and Korea only 9% and 30% males voluntarily admit to having ED (2) and in most of the other countries in Asia, it is still considered very sensitive with considerable social stigma and secretly will resort to herbal remedies and tonics before seeking conventional medical help.
L-arginine. L-arginine is an important amino acid that the body needs to build proteins. Because L-arginine has been shown to improve blood flow, some alternative practitioners have recommended that the supplements be used to treat ED. The Natural Medicines Comprehensive Database, which is a reliable authority on alternative medicines, says L-arginine is possibly effective for treating erectile dysfunction. But Harris warns that "although this supplement could improve blood flow, side effects can be dangerous." L-arginine can cause an allergic reaction or worsen asthma in some people; it can also lower blood pressure.
Ginkgo biloba. Known primarily as a treatment for cognitive decline, ginkgo has also been used to treat erectile dysfunction -- especially cases caused by the use of certain antidepressant medications. But the evidence isn't very convincing. One 1998 study published in the Journal of Sex & Marital Therapy found that it did work. But a more rigorous study, published in Human Pharmacology in 2002, failed to replicate this finding. "Ginkgo has come out of fashion in the past few years," says Ronald Tamler, MD, assistant professor of medicine and codirector of the men's health program at Mount Sinai Medical Center in New York City. "That's because it doesn't do much. I can say that in my practice, I have not seen ginkgo work -- ever."
