Numerous remedies are available to treat erectile dysfunctions, or ED 3. Some of these have been shown to be effective, according to MayoClinic.com, while others are not only ineffective but may even be dangerous. It is crucial to consult a doctor before taking any over-the-counter drugs for ED. Since ED is often caused by reduced blood flow from blocked arteries, such lifestyle changes as exercising and keeping weight within a normal range can also improve the condition.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Some patients even reported having normal erectile function within a day from the beginning of the treatment. Unfortunately, L-arginine also has serious side effects such as worsening of asthma symptoms, increased risk for bleeding and gastrointestinal problems.

Yohimbine vs. Yohimbe
According to Drugs.com, dehydroepiandrosterone, or DHEA, is a supplement that may treat erectile dysfunction 45. It has been claimed to enhance sexual desire and functions, improve mental functions, as well as slow down the aging process. Some studies, such as one published in the “Urology” Journal in March 1999 by Dr. W.J. Reiter, showed that erectile function improved after DHEA use. However, some studies have shown no effect, notes the University of Maryland Medical Center 2.
Yohimbe is an evergreen tree that grows in such western African countries as Nigeria, Gabon, Cameroon, Congo and Zaire. The bark of this tree contains several alkaloids, the key alkaloid being yohimbine. Yohimbe is popularly used as an aphrodisiac to increase libido. According the Drugs.com, some studies also show that it may be effective in treating erectile dysfunction that is not caused by a physical problem 45. Yohimbe relaxes and dilates peripheral blood vessels, resulting in increased blood flow to the penis. Yohimbe can also have severe side effects such as hypotension, hypertension, paralysis and abdominal distress.
