From the page: "The Flu of 1918 stands out very forcefully in that the Klenners survived when scores about us were dying. Although bitter it was curative and most of the time the cure was overnight. Several years ago my curiosity led me to assay this "herbal medicine" and to my surprise and delight I found that we had been taking from ten to thirty grams of natural vitamin C at one time. Even then it was given by body weight. Children one cupful; adults two to three cupfuls. Cups those days held eight ounces. Twentieth century man seemingly forgets that his ancestors made crude. drugs from various plants and roots, and that these decoctions, infusions, juices, powders, pills and ointments served his purpose. Elegant pharmacy has only made the forms and shapes more acceptable."
