Menstrual Cramps

My friend has been having excessive cramps during her cycle. She says it runs in the family, but sometimes the pain is incapacitating. She\’s not a fan of drugs (not even ibuprofen), so she tends to \”tough it out\” on a regular basis. Of course I don\’t enjoy seeing her in pain.

I\’ve done some quick searches that say magnesium, calcium, and cannabis will help, but do they really? Does anyone have any tips I could give her to help her out?
