Chasteberry may help relieve PMS symptoms

Although it isn’t as well known as other herbs used by ancient civilizations, chasteberry was popular among the ancient Greeks and Romans for the same reason it’s used today -- to correct hormonal imbalances in women. The reddish berries of the chasteberry tree, which is found in Europe and as an ornamental tree in the United States, contain mild levels of hormones such as androstenedione and progesterone. The berries are also called vitex, and chasteberry supplements are sometimes sold under that name.

Uses: Chasteberry is used by women for hormone-related problems, such as to alleviate the symptoms of PMS, regulate menstrual cycles, promote lactation and boost libido.

Dose: Ranges widely but usually 500 milligrams a day in a capsule. Chasteberry is also sold as a tincture, extract or tea.

Precautions: Considered a relatively safe herb, chasteberry can cause mild nausea or allergic reactions.

Research: One study found chasteberry capsules helpful for treating PMS symptoms. Many studies have not been not scientific enough to prove the herb’s benefits.
