The NY Daily News claims Osama Bin Laden was using an herbal form of Viagra before his death. Avena syrup, which is an extract of wild oats, is marketed as a natural "Viagra." Osama's medicine chest was packed with drugs to treat shingles, ulcers, nerve pain and high blood pressure. Bin Laden's wife said he cured his kidney problems with watermelons. Bin Laden fathered between 20 and 26 children.
