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.
Impotence, or erectile dysfunction (ED), is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse.  To understand the underlying causes of impotence, it helps to know the basics about how an erection develops, along with potential problems that get in the way. Erections begin in the brain with a thought related to sexual desire. Then a chemical message travels from the brain to the penis. Blood flow to the penis increases as blood vessels leading to the reproductive system relax and allow for increased circulation.
Enlargement of the prostate gland, another condition that occurs with increasing frequency in men as they age, can also cause ED. In a 2012 Swiss study, 82 men with moderate to severe symptoms of prostate enlargement, who were also experiencing problems such as ED or loss of libido, took 320 mg of saw palmetto extract daily for 8 weeks. At the end of the study, the men’s ‘International Prostate Symptom Score’ (IPSS), a method of measuring prostate health based on a questionnaire, was reduced by an average of 51 percent. In addition, their ED, libido, and other sexual functions had also improved by an average of over 40 percent. Unlike the drug approaches used in conventional medicine, which can even cause ED as a side effect, saw palmetto is very effective in treating prostate problems and is free from side effects.
Acupuncture. Acupuncture has been used for centuries to treat ED and impotence in China. A recent review of studies on acupuncture for erectile dysfunction was published in the British Journal of Urology International. After reviewing four studies, the authors concluded that there was not sufficient evidence to say that acupuncture worked. However, some experts believe it's worth trying. "Acupuncture can work," says Gilbert. "It probably works best to treat the psychological component of ED. There is very little downside to trying it."
Another age-old therapy for ED is acupuncture. This is an ancient Chinese treatment where thin needles are inserted into specific points of the body to relieve all kinds of illnesses. Acupuncture has been used to treat ED for years. Studies show that acupuncture improves erection as well as in the treatment of erectile dysfunction with psychological cause.18
The truth is medication or psychosexual counselling are the first treatments a doctor will suggest because they’ve been proven to work. If a doctor has approved a medication for you then it’s safe. If you would still like to see if herbal supplements work for you, then there is a list below of supplements thought to work for erectile dysfunction. Just before you invest your money in them, remember they aren’t proven to work:

Do not exceed 1 capsule in 24 hours. This is only intended for those 18 and over. Do not use if you are pregnant, nursing, or intend on becoming pregnant. If you have any current heart issues, such as but not limited to, hypertension, heart disease, and high cholesterol do not use. If you have any other medical issues such as prostate cancer and prostate enlargement do not take. Do not take this product if you're on any medications such as MAOI's or nitrates. Consult with your physician or health care provider to using the product.

lung issues, neuropathy, arthritis, vision problems, thyroid dysfunction, erectile dysfunction etc. etc. are all due to depression. I think you are dead wrong! ALL of these are documented potential side effects of interferon, in the literature. Its just that the literature does not indicate that the problems might persist long term in a significant group of patients. How are you so certain that the interferon has nothing to do with these problems again????
With drug therapy, there’s a risk of side effects such as headaches, back pain or an upset stomach. Before taking any medication for erectile dysfunction it is important to ensure your doctor is ok with that decision. Medication may not work for all men, for instance, if you have diabetes or have previously had prostate surgery. ED medication might also have serious risks if you’re currently taking nitrates (commonly prescribed for chest pain), have heart disease or have low blood pressure.22
For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact.
