Essential oils have been used for centuries, it was the medicine people took before you could drive to your local pharmacy and pick up whatever you needed. I have PCOS and with that comes cyst and lots of pain with my period. I remember growing up and falling over in class because my pain was so great. I was always carrying around OTC pain relievers because I never knew when my period would come and knock me off my feet(literally) I am all for finding a natural way to combat my pain when need be.
