Erectile dysfunction (ED), or the inability to maintain an erection, is usually caused by physiological problems not psychological ones. Garlic, unlike medications for erectile dysfunction, has no known negative side effects, and is sold in the United States to reduce high blood pressure and cholesterol by lowering triglycerides. Garlic may lower cholesterol by 6 percent to 12 percent and improve erectile dysfunction.
Although more common in older men, a man of any age can suffer from erectile dysfuncion. Common causes of erectile dysfunction are heart disease, high blood pressure, obesity and prescription antidepressants. Several Asian remedies treat erectile dysfunction.
