What should I do if there is retained tissue in the uterine cavity and I took Yimucao (Leonurus herb) but didn't experience any bleeding?

Generally, if there is retained tissue in the uterine cavity and no bleeding occurs after taking Leonurus herb (Yi Mu Cao), this may be due to insufficient medication duration, individual insensitivity to the drug, tightly adhered residual tissue, weak uterine contractions, or organization of the retained tissue. It is recommended to seek medical attention promptly, identify the underlying cause, and follow a doctor's guidance for appropriate treatment. Specific reasons are analyzed as follows:

1. Insufficient medication duration: Leonurus herb requires a certain amount of time to promote uterine contractions; short-term use may not achieve the desired effect. Continue taking the medication as prescribed for 3–5 days and monitor vaginal bleeding. Avoid stopping or adjusting the dosage without medical advice to ensure consistent drug efficacy.

2. Individual insensitivity to the medication: People may respond differently to Leonurus herb, and some may experience only weak uterine contractions after use. Follow your doctor’s instructions to adjust the treatment plan, possibly combining it with other medications such as Xinshenghua Granules, Xuefu Zhuyu Capsules, or Shaofu Zhuyu Pills to enhance the expulsion effect.

3. Tightly adhered residual tissue: When residual tissue is firmly attached to the uterine wall, medication alone may not effectively dislodge it. Under medical supervision, increase the dosage or combine medications, and engage in light walking to improve pelvic blood circulation and assist in expelling the residue.

4. Uterine atony (weak contractions): Poor uterine recovery after childbirth or surgery can lead to inadequate contraction strength, making it difficult to expel residual tissue. Follow medical advice to use drugs such as Oxytocin Injection, Misoprostol Tablets, or Carboprost Methylate Suppositories to strengthen uterine contractions and facilitate removal of the retained material.

5. Organized residual tissue: Prolonged retention of tissue can lead to organization (fibrous integration with uterine tissue), which responds poorly to medication. In such cases, hysteroscopic removal of intrauterine remnants is required. This minimally invasive procedure precisely removes the organized tissue, helping prevent complications like intrauterine adhesions or infection.

In daily life, maintain good personal hygiene, change underwear regularly, and avoid sitz baths and sexual intercourse to prevent infection. Eat a light, nutritious diet rich in protein to support uterine healing. Schedule regular follow-up ultrasounds to monitor the clearance of residual tissue and adjust the treatment plan as needed.
