Meets the Traditional Chinese Medicine (TCM) diagnostic criteria for Kidney Deficiency and Blood Stasis Syndrome. Male, aged between 22 and 65 years old. Blood sugar has been well controlled for the past 3 months: Glycated Hemoglobin (HbA1c) = 7%, fasting plasma glucose (FPG) = 7.0 mmol/L, and 2-hour postprandial glucose (2hPG) = 10.0 mmol/L.

The subject is informed, and either the individual or their family has voluntarily signed the informed consent form.

Exclusion criteria

Exclusion criteria: 1. Subjects with significant penile deformities such as micropenis, congenital penile curvature, penile fibrosis, or a history of related surgeries involving the prostate, pelvis, or lower abdomen. 2. Subjects with erectile dysfunction caused by other sexual dysfunctions (such as ejaculation disorders, premature ejaculation) or incurable endocrine diseases (e.g., hypogonadism, hyperprolactinemia, hyperthyroidism/hypothyroidism, Cushing's disease, or pituitary insufficiency). 3. Subjects with a history of severe psychological factors or mental disorders, or those with severe anxiety (GAD score = 15) or depression (PHQ score = 15) or who are unable to discontinue anti-anxiety or antidepressant medications during the trial. 4. Subjects with erectile dysfunction caused by spinal cord/nerve injury, radical prostatectomy, or other trauma, surgeries, or radiation therapy. 5. Subjects with a history of the following heart conditions: a. Myocardial infarction, shock, or life-threatening arrhythmia within the last 6 months. b. Unstable angina within the last 3 months or a history of angina during sexual intercourse. c. Coronary artery bypass graft surgery or percutaneous coronary intervention within the last 3 months. d. Heart failure (NYHA Class II or above) within the last 6 months. e. Uncontrolled arrhythmia. 6. Subjects with acute diabetes complications within the last 3 months, such as diabetic ketoacidosis or hyperosmolar non-ketotic coma, or with significant chronic complications such as proliferative retinopathy, stage IV or more severe renal impairment, or severe diabetic neuropathy. 7. Subjects with severe renal disease or estimated glomerular filtration rate (eGFR, CKD-EPI formula) = 60 mL/min/1.73 m². 8. Subjects with poorly controlled blood pressure (defined as systolic pressure = 180 mmHg and/or diastolic pressure = 110 mmHg) or with clinical hypotension. If a subject meets this exclusion criterion, a second measurement can be taken after at least 30 minutes, and the second result will determine the subject's eligibility. 9. Subjects with significant liver disease or acute or chronic hepatitis, or laboratory tests showing ALT or AST = 3 times the upper limit of normal (ULN) and total bilirubin (TBIL) = 2 times the ULN. 10. Subjects with a history of severe central nervous system damage (e.g., cerebral ischemia, stroke), inflammatory brain diseases (e.g., encephalitis, meningitis), traumatic brain or spinal cord injury, or peripheral neuromuscular disorders within the past 6 months. 11.
