One forth of all Americans ingest acetaminothen, also known as paracetamol, on a regular basis. This is the pain reducing ingredient in Tylenol and over 600 other over-the-counter drugs. Although used as a physical pain relief, the research into its psychological pain reducing effects are bringing some important questions and issues to the forefront. DR. DOMINIK MISCHKOWITZ is leading some of this cutting edge research. It is to his credit and our benefit to combine the research of the psychological and pharmaceutical effects of this and other drugs.
