Treat Hypothyroid and PMS Simultaneously with Chaste Tree Herbal Supplement

Dr. Michael Ruscio: Hi, this is Dr. Ruscio. Hypothyroid, PMS, and the magical herb—what’s the connection? Well, the magical herb is called chaste tree. And I don’t know if it’s necessarily magical, but it’s certainly a novel herb. And let me break down for you how the herb chaste tree can have an effect on both low thyroid function and female hormones and fix both at the same time.

So if you look at this schematic, it’s a little bit detailed, but I’ll walk you through it. The herb chaste tree actually acts in the brain to help balance out levels of your happy mood chemical called dopamine. We have to have appropriate levels of dopamine not to be anxious, to have mental energy, and to be able to focus.

Now, as chaste tree balances out dopamine, it inhibits another hormone in the brain from going high called prolactin. And what prolactin will do when it goes high is it will shut down the ovaries’ proper release of progesterone. And when you don’t have good progesterone levels, you are more prone to have PMS and to have lower thyroid function.

So the tie in between thyroid and progesterone is that progesterone, like I said, has a direct influence on thyroid function. And this is why when women go to infertility clinics, they’re actually given a body temperature chart because right after you ovulate, your body temperature goes up and stays up for the second half of your cycle because after you ovulate, you produce much more progesterone. Progesterone helps turn on thyroid hormone. Thyroid hormone makes you hot amongst other things. So that’s that connection there.

Now, I want to show you a quick study here. This study showed that, as far as PMS goes, 93% of women who took chaste tree for three consecutive cycles saw either elimination or reduction in their PMS symptoms. So there’s certainly some good research out there about chaste tree. And there are a number of people that chaste tree will be good for.

But there are also some women that chaste tree won’t work for. Women who are no longer cycling, it won’t have the desired effect. And there are a few other caveats with chaste tree. But certainly an herb that is generally safe and one that can help a lot of women who have both these issues at the same time. Just always be careful when using herbs. And if you have any questions, you can always let us know.

You can get chaste tree in capsule, tincture, or dried berry form. Our recommended protocol is below.

    1. Mary,
      Correct, at least not through the mechanism of prolactin/dopamine. Adrenal support can help with both female hormones and conversion of thyroid hormones. So this is a good option. Hope this helps 🙂

  1. What was the dose amount in the study? And did the participants take the chaste berry during their cycle as well as the rest of the month?

      1. Thank you. For posting the study. The 40mg seems to be the active chemical not the plant matter it’s self. For example the supplement I can access in the store is 400mg / capsule that one is plant matter. This study is also demonstrating the improvement in results from a pharmacitical perpetration vs plant ingestion which I have seen 1000mg reccomended doeses. Please as always correct me if I am wrong.

  2. I’m menopausal have hashimotos and use BHRT but I also have low dopamine. My experience with herbs has been that they are causing my WP thyroid NOT to work. What else will raise dopamine?

    1. Hi Apelila,
      My first question would be how has your low dopamine been diagnosed? Many of the functional medicine test for dopamine are not valid. It’s likely your dopamine doesn’t require any direct treatment other than good dietary and lifestyle practices. Also, if your on BHRT then you don’t really have to worry about the dopamine/prolactin progesterone connection b/c you are already getting your progesterone 🙂

  3. So.in essence,this chaste tree won’t help menopausal women whose thyroid is way whacked up..right?

    What help us?

  6. The effect on dopamine sounds very interesting! Wondering if this effects someone in recovery from addiction – i.e. nicotine, alcohol, & other substances.

    1. Since this herb reduces prolactin levels, I would assume that it would NOT be recommended for nursing moms. Maybe Dr. Ruscio can confirm my thoughts.

  8. currently i am on medicine for Hypothyroidism …can i take vitex along with it….at what time i should take it..

  9. Would chaste tree supplementation be helpful in regulation of hormones for my gf who has not been having her period?

  14. HI I was just told I have high thyroid level and I need to go to an endocrinologist. I’ve been taking chaste berry to help with conception. I’ve had my thyroid tested before and it was always normal. I was wondering if taking chaste berry could have raised my levels if I didn’t actually need it. Thanks!

    1. Hi Andrea,

      I’m not aware of any connection or reaction between the two, but definitely something to mention when you see your doctor. Good luck!

      1. when you say you aren’t aware of any connection between the two (thyroid levels and chastebery); isn’t that what this article is about? This article specifically discusses the connection via prolactin and progesterone. So what do you mean by your response?

        1. Hi Jane,

          Apologies, I should have been more clear. I meant that I’m not aware of any connections between chaste tree and hyperthyroid.

  16. I am Suffering from Hormonal imbalances with progesterone drop before monthly cycles leading to catamenial epilepsy. I also had hypothyroidism a year and I stopped thyronorm 25 mg two months ago after my levels came to normal. I was on epileptic drug for 32 years not knowing that the catamenial epilepsy is due to progesterone drop before cycles. I am on Chasteberry for a month now, I have stopped all the epileptic drugs. Suddenly I noticed hairfall, when I did my thyroid I came to know that my thyroid levels have increased to 5.5, please guide me as what should I do. Can I start thyronorm 25 again empty stomach in that case will it interfere with Chasteberry.

  18. I read in the instructions on the bottle that vitex should be taken early morning on empty stomach, but I intake synthroid first thing in the morning.
    Could you please advise how I am supposed to intake synthroid and vitex?

    1. Spacing them out would be ideal, so Synthroid first, followed by vitex later (but still before your first meal). You can also discuss with your doctor and get their input.

  20. I am going through menopause. I haven’t had my period in about 3 years however I’ve been having hot flashes and night sweats. Will this help with the hot flashes and night sweats?
    Thanks in advance

    1. Hi Denice,

      Chaste tree berry isn’t typically recommended for people who are no longer cycling. You may want to ask your practitioner about black cohosh or dong quai. Good luck!

  22. I know this post is about hypothyroidism and chasteberry, but my question is about how chasteberry may impact hyperthyroidism. I was diagnosed with Grave’s Disease when I was pregnant with my first child nearly 4 years ago. I now have 2 children and my thyroid hormone levels have fluctuated to varying degrees this whole time and I have mostly had to remain on some dosage of propythiuracil (PTU) to control it. About 3 months ago, my thyroid hormones began to increase out of normal range. Note: I have not produced TSH for these 4 years. I remained on the same dose of PTU, but also noticed I began having acne problems and a noticeable increase in PMS irritability. I decided to try chasteberry to correct the acne and PMS. I got a blood test for my thyroid hormones several weeks after I began the chasteberry and was surprised to see a very sudden correction of thyroid hormone levels. I have since gotten more bloodwork and now my T3 and T4 are now in the low-end of normal while my TSH has surged well into the normal range. I am hopeful that I may be in remission. Do you believe it possible that the chasteberry may have corrected my Grave’s disease? P.S. It seems to have fixed the irritability, but not the acne. Thank you!

    1. Hi Jennifer,

      While chasteberry is usually most helpful for hypothyroid, It’s possible that it may have exerted an effect on your pituitary gland, causing a decrease in overproduction of thyroid hormones. Hope your improvements continue!

  24. I recently started taking 2 ml vitex, 2x/day as well as a chinese herbal blend called EaseTonic, 2x/day to help regulate hormones due to severe cyclic mood and mental processing disturbances that correlate to my menstrual cycle from ovualtion / post ovulation up until menstruation when everything returns to normal.
    I also take Nature-throid for Hypothyroidism.
    My latest bloodwork shows a significant increase in my Free T3 levels w/out any change in my dosage of Nature-Throid and I am now actually well out of range on the High side! I would now look to be HYPERthyroid, and seem to be experiencing those symptoms.
    I have been having issues with sleeping and with anxiety and depression / lack of motivation since August…started the Vitex / herbal treatment in July, bloodwork was taken mid September.
    Could it be the Vitex that is increasing my Free T3 levels??? Is the Vitex helping my thyroid to the point dosage should and can be reduced? Or should I not be taking the Vitex?
    I have an appt. scheduled w/my Doctor, however I am trying to get as much info preliminary to that so as to know the right questions to ask ahead of time.

    1. Hi Krit,

      I’m not aware of vitex causing hyperthyroid. That being said, everyone is unique and reacts to supplements in different ways. Unfortunately, I’m unable to offer any personalized medical advice or diagnosis on this forum, so you’ll have to check in with your doctor. I hope you’re able to get to the bottom of it – keep us updated!

      1. Thank you for your reply (which I am JUST now seeing)!

        I have currently dropped the Vitex, reduced Thyroid medication, and started monitoring hormones mid luteal phase since my appt. w/the Doctor. It’s been a couple of months, and 2 menstrual cycles of checking mid phase seem to indicate progesterone is on the low side. But, the reduction of the thyroid meds seems to have finally leveled out the bloodwork again, which is what I wanted to get under control FIRST to then add back in the Vitex and see the effect more controlled and with regular checking of the bloodwork.

        I think I may have been taking too much of the Vitex as well as I am fairly sensitive to most supplements, and plan to cut it in half.

        There is conflicting information regarding taking Vitex all month or taking Vitex only during the luteal phase. What is the position of Ruscio Institute on dosage and frequency?

        1. I believe Dr Ruscio is ok with it being taken all month long, but check in with your practitioner since they know you best and can give a personalized recommendation.
