PMS, or Premenstrual Syndrome, occurs as a result of hormonal imbalances. I strongly recommend putting PMS patients on herbal formulas, like a customized version of Xiao Yao San.
There are a number of acupuncture treatment options. One of my favorites is:
Du 20, Yintang
Right side: Gb 34, Gb 36, and Gb 39.
For patients with strong anger and Liver imbalances, I often add Wood 11.17, also called Wood Anger in some references.
