The removal of blood is still used to treat people with hemochromatosis - excess iron in the body. The goal is to induce a slight anemia to drain the excess iron from the tissues back into the circulation.
The practice of bloodletting for high blood pressure is fraught with danger to the patient. To be effective a quantity of blood would need to be removed to induce shock which opens up a whole new can of worms.
I remain unconvinced.

Yup. My wife has genes H63/H63 (a defective gene from each parent common among Scotch/Irish) resulting in hemochromatosis.
I was shocked when the MD said he might have to bleed her regularly if her iron level (which was elevated) stayed too high...just like in the Middle Ages.
