Soaked raisins and Kesar (saffron), when taken together, not only help soothe period pain, but can also help your deal with PMS mood swings. Having 4-5 overnight soaked raisins with some Kesar, the first thing in the morning has proven to be quite effective on menstrual pain. One can also start taking them a week before their period if they know their dates. Raisins act as a natural laxative and help to keep your digestion process in check, while studies suggest that Kesar may affect serotonin activity, which is good for PMS as well as depression.
