Is Vitex Safe?

Vitex is another name for chasteberry, or Vitex agnus-castus. The dried berries of the shrub have a long history of use, mainly for treating female conditions, although monks took the herb in the Middle Ages to dampen sexual desires. Vitex may be beneficial, but it may produce mild side effects in some people. The use of herbs like vitex is an alternative approach to health, but consult your doctor before treating any medical condition with an herbal remedy.

Vitex: Herbal Properties

Vitex contains flavonoids, glycosides, essential oils and essential fatty acids. A combination of all of these constituents is thought to be necessary to achieve beneficial results. Controlled studies of interactions between Vitex and other compounds are not available, but talk to your doctor about potential interference with any medications you're currently taking.

Activities

According to "Herbs & Natural Supplements: An Evidence-based Guide," Vitex's main activity is its ability to act on the pituitary/hypothalamic axis. By doing this, Vitex, may reduce prolactin, which, in turn, may reduce physical symptoms. Vitex may also bind estrogen receptors and increase progesterone levels, making it potentially beneficial in treating some female conditions. Because Vitex may affect hormonal levels, people with estrogen-sensitive tumors should not take this herb, unless directed to do so by their doctors.

Potential Uses

By increasing progesterone, Vitex may assist in regulating fluctuating hormones during menopause. Although clinical studies are necessary to verify the benefits, Vitex may ease hot flashes, night sweats, moodiness and other menopausal symptoms.

Vitex may also relieve premenstrual syndrome, or PMS. Females may use the herb to reduce breast pain, constipation, headache, mood swings and depression, according to "Herbs & Natural Supplements." Scientific evidence backing these claims is lacking, however. When taken as directed on the package, Vitex is generally safe, but you should stop using it and contact your doctor if you experience any side effects.

Considerations

Side effects from taking Vitex are generally mild and may include a rash, dizziness or gastrointestinal symptoms. The National Center for Complementary and Alternative Medicine warns pregnant women and those taking birth control not to use Vitex.
