(3) Have taken herbal or botanical medications (e.g.,Xiangshao Keli, livermint, etc., or similar medications), or psychotropic medications (selective 5-hydroxytryptamine reuptake inhibitors, 5-hydroxytryptamine norepinephrine reuptake inhibitors, and monoamine oxidase inhibitors) that may affect the evaluation of efficacy within 4 weeks prior to the screening visit or have used tamoxifen, toremifene, raloxifene, or any other selective estrogen receptor modulators or aromatase inhibitors;
(4) Artificial menopause (bilateral oophorectomy, hysterectomy, destruction of ovarian function by radiotherapy, etc.), untreated unexplained irregular vaginal bleeding, endometrial polyps > 1.5 cm, endometrial (double-layer) thickness ≥ 0.5 cm on ultrasound in the late menopausal stage (except for those without endometrial pathology detected by diagnostic curettage or hysteroscopy), uterine fibroids with a diameter of the largest uterine fibroid > 3.0 cm, or submucosal fibroid, or diagnosed or suspected sub-mucous uterine fibroid. Fibroid, confirmed or suspected pre-cancerous lesions (e.g. endometrial atypical hyperplasia/endometrial intraepithelial neoplasia, etc.) or malignant tumors of the uterus and its adnexa;

(6) Pelvic tuberculosis or purulent pelvic inflammatory disease, or planned pelvic surgery during the trial;
(7) Comorbidities with severe cardiovascular, hepatic, renal, neurological, hematopoietic, or malignant neoplastic diseases, or psychiatric disorders that, in the judgment of the investigator, require the administration of medication for antidepressant or anxiolytic treatment, which may affect the judgment of efficacy and safety;
(8) Combined hypertension but poorly controlled blood pressure (systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg) despite standardized treatment with medication and possible hypertensive crisis, or poorly controlled hypotension (systolic blood pressure ≤90 mmHg and/or diastolic blood pressure ≤60 mmHg);

(12) Women who are pregnant, breastfeeding, or have a request for childbearing from the Screening Period to 3 months after discontinuation of the drug, or plan to use a hormonal contraceptive method or other contraceptive method with a sex hormone component (e.g., Mannitol, etc.) for contraception during the study period;
