Blistering of the skin was a standard method to draw evil humors from the body. Given that the president was sick with pneumonia, the President's physicians tried blistering the right side of his chest. The President did not improve.
Next, the doctors applied suction cups to the blistered skin to draw out the evil, elusive substance that weakened him. Then the doctors gave him ipecac to induce vomiting. They also gave him calomel and castor oil to purge his bowels. Then they administered sedative to the fast-weakening President in the form of opium and brandy. As a last resort, they tried Virginia snakeweed, a Seneca Indian remedy. Nothing worked. 1aHarrison died one month to the day after his inauguration.
