coffee enemas are absorbed into the blood and of course find their way to the liver. In fact the portal vein, which sits atop the rectum, feeds blood to the liver from the lower digestive tract so that it may be cleansed. Hemorrhoids can be caused by a congested liver as the back pressure increases. coffee enemas can relieve hemorrhoids by flushing bile and relaxing the ducts and valves as well as the acids having detoxifying effects. However most sick people muscle test weak to coffee so I think there are better substances to use.
