Are there any effective alternative therapies for treating menstrual disorders?

Menstrual disorder. Depends on what kind of mentrual disorder you are referring too. There are many types of menstrual disorders with many types of treatment.
Unlikely. The causes for menstrual disorders and varied and the treatment needs to be specific to the diagnosis.
May try.. Make sure you are diagnosed first. For simple menstrual cramps, always look at your diet. Drop the amount of salt in diet. Eat foods rich in magnesium such as whole grains, nuts, leafy greens and seeds. Also there are some studies looking at omega 3 fatty acids found in salmon, sardines or fish oil capsules. And there is the old "stand by" a heating pad.
