Chaste tree berry, also widely known as chasteberry and vitex, may get its name because historically it was used by monks it to make it easier to maintain their celibacy.  Now this “female” herb is most commonly used for irregular or infrequent menstrual periods, premenstrual syndrome, and hyperprolactinemia.

According to the Natural Medicines Comprehensive Database, Chaste Tree Berry has been used safely when taken orally in studies lasting from 3 months to 1.5 years.  It should be avoided during pregnancy and lactation, however, due to its possible hormonal effects, and women with hormone sensitive conditions, such as breast, uterine and ovarian cancer, and endometriosis and uterine fibroids, show discuss using it with their physicians.

Chaste tree berry may have an immediate effect but it could also take 4-6 months for complete relief from symptoms of most conditions.  In the tincture form, which I recommend, the dose is 40 drops each morning with some liquid, according to the German Commission E (The German government’s herbal oversight commission).  In the capsule form we have in our office, it is 1 capsule between meals daily.  I most frequently recommend chaste tree berry to women who are perimenopausal and having erratic periods to try to get back on a regular schedule.
