Sometimes a plant holds a lot more than meets the eye (many times, actually). I’ve written before about the health benefits of herbs and spices, and today I’d like to cover an herb we don’t hear about every day but that every woman should know about. Ever heard of vitex?

Also called chaste tree or chasteberry, vitex is a large and graceful shrub with purple flowers similar to a lilac. Gardeners love it for its striking blooms and pleasant scent, but those who know about medicinal plants prize it for other reasons.

What Is the Vitex or Chaste Tree Plant?

The vitex plant or chaste berry tree (the Latin is Vitex agnus-castus L., if you want to get technical) is native to Asia and the Mediterranean. Cultures in China, Greece, and Italy used vitex long before its introduction to the United States. Now it’s commonly found in southern gardens because of its ability to withstand warmer temperatures. Vitex is also known as “poor man’s lilac” because of the similarity of the bloom appearance.

In our case, it’s not the landscape we’re after, but the fruit of the chaste tree. This small brown berry (known as the chasteberry) is edible and has a peppery flavor.

Use of the chaste tree berry for medicinal purposes dates back over two thousand years. Many believed chasteberry could suppress libido (although there is no scientific evidence that it does.) The Greek physician Dioscorides prescribed it to soldiers’ wives so they could remain “chaste” while their husbands were away at battle. In the Middle Ages it is said that monks took it to help with the vow of chastity. This is also why chasteberry is known as monk’s pepper.

Vitex Benefits for Female Health

Basically, if you’re a woman, this herb can probably help! When it comes to easing symptoms of PMS — breast tenderness, cramps, cranky mood, and all — vitex is the queen of herbs.

Eases Symptoms of PMS and PCOS

Many clinical trials show chasteberry’s ability to ease PMS and menstrual-related difficulties. Compounds in vitex bind to certain pain receptors, which eases pain in addition to the hormone normalizing effect. In one randomized double-blind, placebo-controlled study (translation: very credible), 178 women took vitex in capsule form for 3 full cycles. Compared to the control group, the women in the test group experienced 50% improvement/reduction in symptoms. These include mood swings, anger, irritability, headache, breast tenderness, and bloating.

This is good news for PMS and even PCOS sufferers, especially with the generally safe profile of this herb.

Supports Progesterone and Luteinizing Hormone

Luteinizing hormone (LH) is important to a healthy reproductive system and largely responsible for triggering ovulation in the body. Studies on chasteberry show the herb supports LH production, which in turn normalizes progesterone and the luteal phase of the menstrual cycle. This is valuable if it corrects a luteal phase defect, which may contribute to infertility and even miscarriages.

For these reasons, vitex is widely prescribed by doctors in Germany and other parts of Europe for endometriosis. (Doctors prescribing natural remedies? It can happen!)

Regulates Irregular Menstrual Cycles

As I mentioned, vitex is especially helpful for those with irregular cycles since it helps balance female hormones. This applies also to those coming off of hormonal birth control, as it can take years for the cycle to completely regulate on its own. I know it’s a controversial subject, but there are many reasons to consider the switch from hormonal birth control to more natural alternatives.

May Help Memory and Brain Function Post-Menopause

Chasteberry’s balancing action on the hormones also may make it useful for some women during menopause. A 2015 study published in Basic and Clinical Neuroscience found that giving rats vitex extract orally improved memory and learning. The thought is that vitex protects against “menopause-related cognitive decline” with fewer side effects (read: cancer risk) than other forms of estrogen replacement.

Less Certain Claims

Some herbalists suggest vitex to help with fertility and even through the first trimester to help prevent miscarriage. While larger studies need to be done in regard to fertility/pregnancy to know its true impact, smaller studies suggest a connection. It is difficult to know the true effect since some of these studies were small pilot studies or used other herbals along with the vitex.

It seems that the claim that vitex can restore missing periods (amenorrhea) are overblown based on current data. At most, the research indicates it may help luteal phase defect by evening out irregular periods.

Interestingly, although many cultures have used vitex to support lactation and boost milk supply, there is little scientific data to support this at this time. This study suggests scientists aren’t really sure if it hurts or helps, so more research is needed.

How Vitex Works

How exactly does a plant accomplish these things? Current scientific understanding suggests that vitex works by regulating and supporting the pituitary gland, which is considered the master gland for hormone production.

This article explains:

There are several different theories about how it works:

  1. Binding dopamine receptors, which works to reduce secretion of prolactin by the pituitary gland, in turn inhibiting estrogen and progesterone.
  2. Binding opioid receptors, which decreases the secretion of gonadotropin-releasing hormone.
  3. Vitex contains many estrogen-like compounds that have an impact on the menstrual cycle.

Since vitex works by correcting hormonal imbalances, it is not a fast-acting drug but a long-term remedy. In studies participants supplemented with vitex for as long as 3-5 months before measuring results.

How to Use Vitex

Vitex is available in capsule form or tincture form. It has a bitter taste, so often capsules or a tincture with other herbs is the best option. The most inexpensive option is to grow or order the dried berries and make a tincture at home. To make a tincture, the proportions from this recipe can be used with just vitex in place of the other herbs.

As I mentioned, vitex acts slowly, so it often takes several months to see its full effect. Since it supports the body’s own hormone cycle rather than providing any hormones itself, it works more slowly while the body adjusts to normal hormone production.

The University of Michigan Health website recommends 4 months of use for noticeable effects, with a daily dosage of 40 drops of tincture/concentrate or 1 capsule (powdered).

Caution/Side Effects of Vitex

Given its long historical use, vitex seems to be a very safe herb. I definitely recommend checking with a doctor before taking even natural supplements or herbs, especially when pregnant or nursing.

Mild and infrequent side effects reported include nausea, headache, stomach upset, and skin irritation. According to this article, women with a history of depression should avoid taking vitex.

Those using hormonal contraceptives should use caution when taking vitex due to its hormonal effects. There’s no evidence that vitex interferes birth control but it makes sense that there could be some interaction.

Finally, be aware that vitex may cause some changes in the menstrual cycle. This will stabilize over time, but if you chart your cycle for natural family planning purposes, expect to see some irregularities while your body adjusts.

It is not recommended for men, though maca is a great fertility-promoting herb for both men and women.

    Hi Katie,
    I’m curious about this in affect with nursing. I’m still nursing my 17m old and my cycle hasn’t returned. I don’t think I’m infertile, and I have a false period it seems each month without spotting so after reading this I was thinking it may help.

    What are your thoughts? Did you use this?

    I starting vitex when my son was 8 months old and still breastfeeding. Then 3 months later (still breastfeeding) I became pregnant. I miscarried at 10 weeks due to blighted ovum. It is now 2 weeks since my m/c. I have weaned my son and hope to become pregnant very soon. Should I take vitex again or do you think it caused the miscarriage? Can it mess cycles up at all or only help? Also, I noticed mid-cycle spotting while on vitex. Does this mean I shouldn’t be taking it? I find it so difficult to find people who actually know anything about this subject. Thanks!!!

      To update those who are thinking about taking vitex. After several months of weird cycles after the miscarriage, I got back on Vitex. 3 months later I was pregnant, so it really works.

        Thanks a lot!!! I highly appreciate people who take out the time to update the results.

        One question, as you have taken it during breastfeeding, Does it increase the milk supply as well? I have a 7 month old son and thinking of taking it for increasing my milk supply.

          No it stops prolactin released by your pituitary which is almost the opposite of creating milk. Try fenugreek fennel or aniseed teas

        Hi Lisa! Did you continue to take Vitex while pregnant as well? I’m 5 weeks today and began taking Vitex just last month to lengthen my luteal phase (began day 1 of my cycle) :). Just trying to research how long I should continue taking it for. Thank you!

    Hello kati,

    Just started on Maca and Vitex from day one to date. I don’t seem to have any serious problem but we can’t conceive even with ivf in the last 2 years. We have 7 failed ivf. My progesterone seems to reduce even when am on progesterone tablets. I thought its progesterone deficiency so I decided to try both maca and vitex together. My periods are regular but very scanty and comes for three days only at times two days. My tests shows that my uterine lining is ok, I even uterine scratching to help shed any stagnante blood and that time I bled for four heavy days. Now, I have saw boobs, headaches, mild pelvic cramps, bloated and feeling full all the time. My last period was 4th March 2014, with these feelings, do you think I might be pregnant? I have not tasted ‘yet, waiting to see if AF comes on. My cycle range between 29 days and 31 days.

    I recently purchased vitex tincture, maca, and prenatal vitamins in hope to regulate my periods and I would like to have children with in the next year. This last year has been very stressful for me and I have a history of irregular periods but I think the stress makes it worse. Is there anything else I could take to help this process along? am I taking the correct herbs and vitamins?

    Hello,
    I just wanted to add my experience with vitex. I’ve had very irregular cycles for as long as I can remember. My two last cycles were 92 days and 75 days long. I’ve been taking vitex and this time my cycle was only 41 days, which is great news for me 🙂 So as far as I can see, it (as well as a lot of prayer!) has helped shorten my cycle length. I was also diagnosed with hypothyroidism and am taking levothyroxine everyday. We’ve been trying to conceive for about a year with no luck yet. My question is, do you think vitex is the right herb for me to be taking to increase fertility or should I try Maca as well?
    thank you!

    Hi Katie. I had my son in 2011 and my periods have been irregular ever since. They lasts between 5-7 days but comes every other week, sometimes 3 times a month. Can Vitex or Chasteberry help regulate it? Please help!

    Hi Katie can you please help me! I started taking chaste tree just over a month ago (Dec 22) (1 cap 300mg p/day, also contains Dong Quai) to help shorten my 44 day cycle as maca didn’t seem to make a difference. Several weeks later I got my period at a 33 day cycle (11-16 Jan) but then the weirdest thing happened I got them AGAIN on 21-26 and again today (30th Jan).
    Is this just how chaste tree works to balance by cycle or should I stop taking it?? Needless to say I am beyond confused and a little freaked out.

      That can happen, but you could take a smaller dose or only take for part of your cycle.
