This tea recipe came from a lady on Undernet #wicca. I myself have not tried it, so I can not verify if it works. she assures me though that this tea will alleviate your cramps and other PMS related symptoms. As with all herbals, make certain you are not allergic and that it is safe for you to consume them. Before taking anything, you should consult your doctor.
Combine equal parts of peppermint, catnip, and juniper berries brewed into a tea. Add honey as desired. Drink and relax.
