患者是一名23歲未婚女性護理師，初經12歲，剛開始的時候月經週期還算正常，直到2年多前開始從事護理工作，她注意到她的月經明顯不正常，有時候會2個禮拜就來月經，有時候會延遲，如果延遲超過半個月，就會至婦產科服催經藥，所以她的月經週期是15到50天左右。2020年5月開始規律至某醫院中醫部服中藥調經，中醫辨證其為肝氣鬱結合肝血虛證，給予疏肝理氣、補益肝血方藥治療，之後月經週期趨於正常，不用再到西醫婦產科催經，故中醫治療對於月經不規則應有幫助。

The patient is a 23-year-old unmarried female nurse. Her first menstrual period was 12 years old. The menstrual cycle was normal at the beginning, until she started working as a nurse more than 2 years ago. She noticed that her menstruation was obviously abnormal. Sometimes menstruation will come in 2 weeks, and sometimes it will be delayed. If the delay exceeds 2 weeks, she will go to the obstetrics and gynecology department to take menstruation drugs, so her menstrual cycle is about 15-50 days. The patient started taking Chinese medicine regularly in the Department of Traditional Chinese Medicine (TCM) since May 2020.
