Two of the most popular natural herbs for hard erections are found in South America. They are Catuaba Bark and Muira Puama. Taken together they are an extremely potent sex enhancer.

Discovery Health recently interviewed a highly respected South American herbalist, who said, "There is nothing that compares with catuaba and muira puama together. I can tell you, I have used these plants with hundreds of people. The old become sexually young again. I have seen impotent men who can have sex for the first time in years. Even healthy couples find that these plants put extra fire in their sex life. These plants are good for men and women."

According to Chinese legend, a goat herder noticed an increase in the sexual activity of his flock after they ate some weeds. Hence the nickname Horny Goat Weed. For over 2,000 years, this famous natural herb for hard erections has held a central place in traditional Chinese Medicine.

According to one well-known Chinese doctor, clinical practices in China routinely use epimedium to successfully treat erectile problems, to boost waning libido, and to rebuild youthful sexual strength.

Epimedium contains icariin, a compound that increases levels of nitric oxide. Nitric oxide relaxes the smooth muscles around the penis, allowing more blood to flow there, resulting in a hard erection.

Maca is a small root vegetable that is grown in South America. According to noted ethnobotanist Chris Kilham, maca is "a turnip that packs a punch," adding "it imparts energy, sex drive, and stamina like nothing else."

Maca used to be consumed by Incan warriors before going into battle. The plant gave them strength and energy. But once a city had been captured they were forbidden to use maca anymore. This was to protect the conquered women from maca-fueled sexual urges.

Today, doctors around the world recognize maca's ability to provide men with hard erections. Arizona physician Gary Gordon, M.D., former president of the American College for Advancement in Medicine, says, "We all hear rumors about various products like maca. But using this Peruvian root myself, I personally experienced a significant improvement in erectile tissue response. I call it nature's answer to Viagra...It acts on men to restore them to a healthy functional status in which they experience a more active libido."

Each one of the herbs described above can be bought separately. But many men prefer using products that contain a combination of natural herbs for hard erections. These products can be potent indeed. One such product is called Endowmax. It contains all the herbs above and more. To find out more about Endowmax--how it works, its ingredients, where you can buy it--just click on Endowmax.
