The Final Word from Linus Pauling
While rethinking your daily aspirin, please consider these remarks made by the late chemist and medical researcher Linus Pauling writing in HOW TO LIVE LONGER AND FEEL BETTER:
"It is drugs, especially the analgesics and antipyretics such as aspirin, that are responsible for most of the five thousand deaths by poisoning that occur each year in the United States. Of that mournful total about twenty-five hundred are children. About four hundred of these children die each year of poisoning by aspirin (acetylsalicylic acid) and some other salicylate. Aspirin and similar drugs are sold openly, without prescription. They are considered to be exceptionally safe substances. The fatal dose is 0.4 to 0.5 gm per kilogram body weight: that is 5 to 10 gm for a child, 20 to 30 g for an adult."
"Aspirin has been in use as a nonprescription drug, sold casually over the counter, for more than a century before the physiological basis of its pain killing and fever-reducing action was discovered in 1971. Then it was found that aspirin acts upon a central hormonal control system in the body. If it were now coming on to the market from a pharmaceutical laboratory, it would be surely placed under the constraint of prescription.
"Some people show a severe sensitivity to aspirin, such that a decrease in circulation of the blood and difficulty in breathing follow the ingestion of 0.3 g to 1 g (one to three tablets.)
"The symptoms of mild aspirin poisoning are burning pain in the mouth, throat and abdomen. Difficult in breathing, lethargy, vomiting, ringing in the ears, and dizziness. More severe poisoning leads to delirium, fever, sweating, incoordination, coma, convulsions, cyanosis (blueness of the skin), failure of kidney function, respiratory failure, and death.
"Aspirin, like other salicylates, has the property than in concentrated solution it can attack and dissolve tissues. An aspirin in the stomach may attach the stomach wall and cause the development of a bleeding ulcer.
"The U. S. Centers for Disease Control have reported that if children and teenagers suffering from influenza or chicken pox are given aspirin they have a fifteen to twenty-five times greater chance of developing Reye's syndrome, an acute encelphalopathy and fatty degeneration of the viscera, causing death in about 40 percent of the patients." 
Should you decide, in consultation with your physician, to replace your daily aspirin with 3-6 grams of oral arginine, you may notice some other interesting effects as well. One effect in particular may negate the need for men to spend upwards of $10 on a Viagra pill.
