Chinese medicine retention enema is to send 100-120ml of Chinese medicine liquid boiled through the anus into the intestinal canal through the enema, so that the drug is absorbed into the blood through the rectal mucosa to play the role of local treatment or systemic treatment. Chinese medicine enema allows the drug to pass through the rectal mucosa, intestinal wall, through the lymphatic vessels communicating with the pelvic cavity and capillaries directly to the pelvic cavity, so that the concentration of the drug in the disease is high, the bioavailability is high, and the local blood circulation can be improved. The drug administered via the rectum has a higher bioavailability than oral drugs, and the effect of the same dose of drugs administered rectally is greater than that of oral drugs. According to the study, the speed of absorption and effectiveness of Chinese medicine enema is faster than that of pills, tablets, suppositories and tonics, with high peak concentration and short peak time. Tubal obstruction is the main cause of female infertility.
