Baloney. Phlebotomy is the preferred treatment of choice for hemochromatosis patients today."It wasn't until well into the 19th century that people began to question the value of bloodletting. Scientists such as Louis Pasteur, Joseph Lister, and Robert Koch showed that germs, not humors, were responsible for disease. Furthermore, medical statisticians tracking case histories began to collect evidence that bloodletting was not effective. Eventually the practice died, although it continued in some parts of rural America into the 1920s."

A Canadian physiologist, Norman Kasting, recently discovered that bleeding animals induces the release of the hormone vasopressin, which reduces fevers and kicks the immune system into high gear. Moreover, leeches are used in modern medicine because they work. Leeches serve as extremely effective artificial veins after replantation of an amputated body part by drawing off the excess blood or the congested blood, until the person can actually grow back small, venous capillaries.
