In the meantime, do what you can to minimize symptoms: eat smaller meals, avoid foods that cause or intensify it, and use over-the-counter medications, if necessary. Here are some treatments for diarrhea you can try at home:

Evening Primrose Oil

Many alternative practitioners recommend evening primrose oil, or EPO, for PMS symptoms. This herbal remedy contains an essential fatty acid called gammalinolenic acid (GLA) and is known as prostaglandin precursor. Alternative medicine practitioners believe evening primrose oil is beneficial for many conditions, including irritable bowel syndrome; it is said to alleviate this condition in women during their premenstrual and menstrual phases. However, to date, there is insufficient medical evidence, in the form of controlled, systematic studies, to show that evening primrose oil reduces PMS symptoms.

While evening primrose oil has its proponents in alternative medicine, a number of clinical studies have found insufficient evidence to support its use or have concluded that it does not provide any relief for PMS. In contrast, one study from the Cedars-Sinai Integrative Medicine Medical Group, published in 2000 in the Journal of the Pharmaceutical Association, Washington, D.C., found that EPO was a reasonable treatment for some women with PMS.
