Herbal viagra
Herbal viagra is a herbal product advertised as treating erectile dysfunction.[1] Many different products are advertised as herbal viagra, but with varying ingredients. No clinical trials or scientific studies support the effectiveness of any of these ingredients for the treatment of erectile dysfunction and some products have been found to contain drugs and other adulterants, and have been the subject of FDA and FTC warnings and actions to remove them from the market.[2]
The name "herbal viagra" is taken from the brand name
Herbal viagras, contrary to what the name suggests, do not normally contain sildenafil citrate. However, sildenafil and chemicals similar to sildenafil have been found as adulterants in many supplements which are sold as herbal viagra or "natural" sexual enhancement products.
Herbal viagras often carry a number of dangerous side effects. Primarily, they cause abnormally low blood pressure and can restrict blood flow to vital organs. Some preparations may be toxic if taken in larger doses.[1] Additional side effects and dangers of common herbal viagra adulterants, such as sulfoaildenafil, acetildenafil and other analogs, are unknown because these ingredients have not had thorough review in human clinical trials.[5][9][10]
Herbal viagra is predominantly sold through the internet, and in 2003 approximately 4% or 1 in 25 of all email spam offered herbal viagra, genuine pharmaceuticals, and other herbal remedies.[11]
