Second edition, revised and enlarged from the first of four years earlier. A very popular work, this relates the author's methods of treatment in an effort to control the symptoms of infectious diseases. Many of his secret remedies were presented here for the first time, with instructions for their use. Helvetius was the first physician to popularize Ipeca (Brazil root) in Europe as a treatment for dysentery; after restoring the Dauphin's health, his father, King Louis XIV of France, funded the publication of Helvetius' discovery. A considerable number of editions of this book were printed, as well as translations into many languages.
