Summary

This study will look at whether Honghua Xiaoyao tablets, a traditional Chinese medicine, can help relieve symptoms of premenstrual syndrome (PMS) in 266 women aged 18 to 40. The researchers will track symptom changes using a daily diary and compare women who take the tablets to those who don't. The goal is to see if the treatment reduces common PMS issues like mood swings, fatigue, and pain.

Who is studied

The somatic symptoms included headache, abdominal distension, limb swelling, breast pain, and insufficient motor coordination. Mental symptoms included irritability, emotional instability, depression and anxiety, changes in sexual desire, physical fatigue, insomnia, and loss of appetite. Behavioral changes are characterized by inattention, accidents, criminality, and suicidal tendencies, and these symptoms disappear after menstruation. The diagnostic basis is that if the above physical, mental and behavioral changes occur repeatedly and periodically during the luteal phase and last for more than three menstrual cycles, premenstrual syndrome can be diagnosed.
