Chasteberry for PMS
Premenstrual syndrome (PMS) affects three out of four women. Can chasteberry help?
Premenstrual syndrome (PMS) affects a significant number of menstruating women, with estimates suggesting that up to 75% experience some form of PMS. The symptoms of PMS are diverse and can range from mild to intense, encompassing both physical and emotional changes. Common emotional and behavioral symptoms include anxiety, mood swings, irritability, depression, changes in appetite and sleep patterns, and concentration difficulties. Physical symptoms often involve joint or muscle pain, headaches, fatigue, weight gain due to fluid retention, breast tenderness, and digestive issues. The intensity of these symptoms can vary greatly, with some women experiencing severe enough effects to impact their daily lives. Typically, these symptoms resolve within four days of the onset of menstruation.
A smaller subset of women suffer from a more severe form of PMS known as premenstrual dysphoric disorder (PMDD). This condition is characterized by debilitating symptoms that recur monthly, including severe depression, intense mood swings, anger, overwhelming anxiety, difficulty concentrating, and significant irritability. The impact of PMDD on daily functioning can be substantial, distinguishing it from the more common and less severe forms of PMS.
These conditions, while differing in their hormonal mechanisms, share some similarities, notably the increase in prolactin (PRL) levels. This elevation in PRL is believed to contribute to premenstrual symptoms and lactation challenges. There is evidence suggesting that premenstrual symptoms may coincide with a condition called latent hyperprolactinaemia (LHP), where PRL levels rise either before menstruation or in response to stress. This increase in PRL could potentially interfere with the development of the corpus luteum, leading to reduced progesterone production during the menstrual cycle's luteal phase. LHP has been linked to several issues, including premenstrual breast pain, benign breast cysts, and infertility.
Vitex agnus-castus L., also known as chaste tree or chasteberry, is increasingly popular in Anglo-American and European herbal medicine, especially for treating various female reproductive issues. There's a growing trend in Western cultures towards using complementary medicines, with women being the predominant consumers. Among these, chasteberry is frequently used for its therapeutic benefits in conditions like PMS, PMDD, challenges with lactation, fertility issues, and symptoms related to menopause.
The big question, of course, is does chasteberry help? What does the clinical evidence say?
