This invention discloses a novel use of M1 (Leonurus glucuronide, ZYZ-488), the main glucuronide conjugate metabolite of leonurine, in the preparation of drugs for preventing and treating endometrial damage and / or intrauterine adhesions caused by mechanical curettage. M1 promotes endometrial regeneration, remodeling, and restoration of endocrine function by increasing serum prostaglandin E2 (PGE2) and / or leukemia inhibitory factor (LIF) levels, while simultaneously restoring serum estradiol (E2) and / or progesterone (P4) levels to normal physiological ranges. It also significantly increases endometrial thickness, the number and regular arrangement of glands, improves stroma density, and enhances tissue morphology remodeling. This invention overcomes the technical bias that Phase II metabolites are typically considered inactivated forms, as well as the thrombotic risks of existing estrogen drugs (EVs) and the strong irritation and insufficient long-term protection of the parent compound SCM-198. It provides a safe, mild, stable, and suitable oral formulation for long-term use, offering a novel and effective drug option for the prevention and treatment of clinical endometrial damage and intrauterine adhesions.
