Chasteberry Benefits: The Herbal Ally for Women’s Wellness

Being a woman isn’t always easy. Throughout life, women deal with hormonal fluctuations each month, and these can continue long after periods stop. Chasteberry (Vitex agnus-castus), is a powerful herbal remedy used by many women that may help alleviate symptoms such as breast pain, mood swings, and other premenstrual syndrome (PMS) symptoms.

In this article, we’ll explore the benefits of chasteberry, including how it might help with the unpleasant symptoms that arise with hormone fluctuations. We’ll also look at the science behind how the Vitex berry may help with issues from fertility and irregular periods to hot flashes and menopause.

What is chasteberry (Vitex agnus-castus)?

Chasteberry is a small, dark-colored berry that comes from the chaste shrub native to areas in Asia and the Mediterranean. The berry itself is about the size of a peppercorn and is typically used as a herbal remedy to address issues such as:

  • PMS
  • Menopause symptoms
  • Fertility issues
  • Other issues related to women's reproductive systems.

It’s been used to alleviate these issues since the times of ancient Greece and is still highly popular in many areas of the world that practice herbal medicine today.

5 potential benefits of chasteberry

Chasteberry is thought to work by lowering inflammation and balancing the hormones estrogen and progesterone. These regulatory effects may be of great benefit to women suffering from hormonal issues related to their reproductive system.

1. May relieve PMS symptoms

Chasteberry is most often used to help alleviate the symptoms associated with PMS. These symptoms include:

  • Constipation
  • Mood swings
  • Breast pain or tenderness
  • Headaches

Scientists think that levels of the hormone prolactin are lowered when Vitex is taken regularly. This, in turn, helps restore the proper balance of other hormones, such as progesterone and estrogen, and PMS symptoms may be relieved.

In one study conducted with 1,634 women experiencing PMS, participants took chasteberry over three menstrual cycles. The results revealed that 93% experienced an improvement in symptoms such as depression, cravings, and anxiety. However, since this study lacked a control group, definitive conclusions cannot be made.

Although some of the other research has shown promising results, the subsequent reviews and analyses have called for better-designed studies to back up the claims behind chasteberry benefits.

2. Might help reduce menopausal symptoms

Low levels of hormones, such as estrogen, during perimenopause and menopause can cause a whole host of uncomfortable symptoms, like hot flashes, night sweats, and low moods.

Research has shown that chasteberry might be beneficial for improving menopausal symptoms like night sweats and anxiety by balancing hormone levels. This could be due to the presence of phytoestrogens in the Vitex berry, which mimic the hormone estrogen produced in the ovaries.

3. May help support fertility

For those preparing their bodies for pregnancy, chasteberry may support fertility efforts. Difficulties with getting pregnant affect many women, and although there are often many causes, one culprit is issues with a shortened luteal phase (second half) of the menstrual cycle. This disorder is associated with having abnormally high prolactin levels.

Chasteberry may influence prolactin levels, lowering them and aiding in the prolongation of menstrual phases and improvement of irregular periods. Several studies have supported the use of Vitex as a fertility aid. One notable study involved 93 women who had attempted pregnancy in the past 6–36 months. It revealed that among those who received the chasteberry supplement, 32% became pregnant, compared to 10% in the placebo group. It's important to note that the chasteberry supplement contained other ingredients, complicating the attribution of results solely to chasteberry.

4. May have anti-inflammatory and antioxidant effects

Inflammation is a normal part of our body’s response to illness and injury. However, if the body continues to send inflammatory cells when there is no longer any danger, the response that is supposed to help can end up harming us.

Chronic inflammation is linked to many health issues including rheumatoid arthritis, heart disease, and gastrointestinal diseases.

Chasteberry contains a number of flavonoids including casticin, kaempferol, and quercetagetin. These plant pigments that occur naturally in a wide variety of fruits and vegetables have anti-inflammatory and antioxidant properties. They may help protect cells from damage from oxidative stress and inflammation.

5. May relieve cyclical breast discomfort

There is a small amount of research pointing towards chasteberry for its potential to relieve cyclical breast discomfort. It’s possible that these effects are due to its ability to decrease prolactin when taken in high doses. High levels of prolactin are associated with breast fullness and soreness at different times during the menstrual cycle. Breast tenderness is also a symptom of PMS.

It's important to note that the research linking cyclical breast discomfort and the potential benefits of chasteberry is limited. More high-quality studies are needed before we can make firm conclusions.

How to use chasteberry

You can take a chasteberry supplement in a multitude of different forms depending on your personal preferences. The chasteberry is usually dried before being made into either liquid or solid extracts which are then used to make tablets or capsules. Vitex can also be taken in liquid form as a tincture or tea and mixed with other herbs that promote healthy hormone balance.

The dosages used in the scientific trials vary, so there isn’t a standardized amount to take. However, it’s best to get advice from a healthcare professional and perhaps start slowly and increase your dosage gradually once you know that you tolerate Vitex well. Always follow the dosing instructions on the packaging as they may vary according to different brands or products.

In terms of finding the best supplements, look for reputable brands that use high-quality ingredients. Make sure your tablets and capsules don’t contain unnecessary fillers or bulking agents.

Always read the label on your chasteberry supplement and do not exceed the brand recommendations for dosage.

Possible side effects of chasteberry

Although chasteberry is generally well tolerated, it’s important to recognize that there are some possible side effects. These could include:

  • Nausea
  • Stomach upset
  • Headache
  • Mild skin rash
  • Increase in pimples
  • Heavier menstrual flow

If you are taking medication such as birth control or hormone replacement therapy, or if you have underlying health conditions, it is advisable to consult your doctor regarding potential interactions before using a chasteberry supplement.

Pregnant and nursing individuals should avoid chasteberry as the effects on babies are not known.

Final thoughts on the benefits of chasteberry

Adding chasteberry to your wellness regimen may provide a number of benefits, including mood improvements, hormonal balance, and general well-being. Vitex agnus-castus may be of particular help to those experiencing discomfort due to PMS or menopause symptoms.

As with any supplement, it's important to use it sensibly and be aware of its limitations and potential side effects. If you are thinking about trying chasteberry or have any concerns about symptoms related to your menstrual cycle or menopause, always seek advice from healthcare specialists.
