Hemorrhoid desiccation

A method of treating advanced-stage internal hemorrhoids using a powder medicine such as Alum Hemorrhoid-Desiccating Powder (枯痔散 kū zhì sǎn) or Three-Shot Gun (三品一条枪 sān pǐn yī tiáo qiāng) to erode away the hemorrhoids and make them dry up and slough off. Because of the danger of arsenic poisoning, this method is no longer widely used. It should not be applied to patients with anemia, hypertension, cirrhosis of the liver, or active tuberculosis.
