Benign prostatic hyperplasia，with a high prevalence in urology and andrology，seriously affects the physical and mental health of middle-aged and elderly patients.The causes and mechanisms of this disease have not been completely clarified.Chinese medicine is effective in the treatment of BPH，and can intervene in the occurrence and development of the disease through multiple pathways and mechanisms，such as improving the hormonal endocrine environment，regulating growth factors，promoting apoptosis of proliferating cells，relaxing smooth muscle，anti-inflammatory and reducing oxidative stress.This paper summarizes the research on the mechanisms of Chinese medicine in the treatment of BPH in recent years.
