I've read a number of articles suggesting cayenne but I get a little skeptical reading claims such as:

"One of his greatest stories in his long career was how he could instantly stop a heart attack if he could get the patient to drink a glass of warm cayenne water. He said, "A teaspoon of cayenne should bring the patient out of the heart attack.""

Were this factual every ambulance in the world would be carrying tincture of cayenne. Outlandish claims such as this destroy the credibility of the author.
