Premenstrual Disorders

been used by many women to help PMS. Called the natural anti- depressant, there is much controversy over its effectiveness. Saint- John’s-wort is another “natural” antidepressant. The herb vitex is believed to help regulate the menstrual cycle by increasing the levels of estrogen and progesterone. (It also helps when menstrual bleeding is a problem, and shrinks fibroid tumors in some women.) Another substance used to stimulate the secretion of estrogen and progesterone is black cohosh root. It is also thought to help with water retention, improve digestion, and calm women— but it has the side effect of causing a heavy menstrual flow. As with any of the natural and herb remedies, these substances must be used with caution. Just because something is said to be natural does not mean it is better. When more aggressive treatment is needed, women should consult someone they can trust before beginning any vitamin or herbal remedy. Light Therapy Studies have been done on the relationship between seasonal affec- tive disorder (SAD) and PMS. Many of the symptoms are very simi- lar: those who suffer from SAD crave sugary and starchy foods; they are depressed, sad, and sometimes irritable. Both their sleeping and eating habits are affected, and their symptoms exist only at certain times (in this case when the days are shorter and there is less light). During the spring and summer these symptoms disappear. While researching different methods for treating PMS, one study used a bright-light procedure much like that used on SAD patients. The women responded well and noticed differences in weight gain, depression, carbohydrate cravings, fatigue, and irritability. Another study that used two hours of bright light daily in the morning showed improvement in PMS symptoms. Others noticed that natural light made a difference—especially for those who spend much of their time under artificial lights either at work, school, or recreation.
