The rectum is located near the anus, thus it is at the exit end of the human body. If there is inflammation in the rectum, venous infusion can be considered. However, since venous infusion enters the body through the blood and then into the rectum, the absorption by the rectum is somewhat poor. For actual rectal inflammation, rectal suppositories or enemas can be used for treatment.

Both Chinese and Western medicines offer corresponding symptomatic drugs for treatment. Rectal infusion is only temporary; the main treatment strategy is still the use of suppositories or enemas, which tend to be more effective because they directly target the intestine, allowing for fuller absorption.

(The use of medications should be carried out under the guidance of a professional doctor.)
