Chasteberry for PMS
Saturday, November 21st, 2009By Curtis Alexander, Pharm.D.
Summary: Chasteberry is actually a fruit from the chaste tree and has a long history of use in many disease states – especially gynecological. There is some good evidence surrounding it’s use for premenstrual syndrome (PMS) and it also appears to be safe and well-tolerated.
Q: My periods are very painful. I’ve taken ibuprofen in the past but I don’t like it as it upsets my stomach and I’d rather take something natural. I’ve heard that Chasteberry might help. Any opinion good or bad?
A: First of all, from the questions I get you’re not alone. A lot of women would love to have an alternative to painful periods outside of over-the-counter drugs that upset their stomach and are just not generally well tolerated. So, lets look at Chasteberry by breaking your question down into two main parts:
Chasteberry is actually a fruit from the chaste tree and has a long history of use in many disease states – most of them gynecological. Because a lot of women who have painful periods. Most of them resort to over-the-counter painkillers like Ibuprofen and the like. Often times, these drugs can upset their stomachs or cause other side effects.
I’m often asked if there is anything they can try that is more natural. One of the first options that comes to mind is a fruit from the Chaste Tree: Chasteberry The two main things I’m going to be concerned about when recommending something new is:
- Effectiveness and…
- Safety
What the Evidence Says…
In the few studies that we do have regarding Chasteberry and premenstrual syndrome (PMS) Chasteberry does appear to be effective. The only drawback to the studies was that they weren’t the best designed in the world.
However, a recent, double-blind (that’s the ‘gold standard’ for medical studies and gives them a lot more clout with the medical establishment) did show significant improvement in self-assessed symptoms of PMS along with physician-assessed symptoms.
The women in the study received a standardized extract of Chasteberry or a sugar pill for three full menstrual cycles. Over 50% of the women saw a 50% or greater improvement in symptoms.
And, as far as safety goes in the trial, patient acceptance of the extract was high with few reported side effects.
One other area that needs to be addressed is possible drug interactions. While you didn’t mention that you are taking any prescription drugs it’s always something you should think about. Chasteberry is no different.
While there have been no significant reported drug interactions with Chasteberry you need to remember that it acts on the dopaminergic system in your body. What this means is that if you are taking any medications that act on the dopaminergic system like Parlodel (bromocriptine which is used for Parkinson’s disease) or Reglan (metoclopramide which is used for stomach issues) there may be drug interactions.
As a woman, remember that Chasteberry cannot be taken during pregnancy and it’s use is discouraged during lactation.
Chasteberry Side Effects
Chasteberry, for the most part, is very well tolerated. If there are any side effects they are generally mild and reported as stomach complaints, dizziness, headache and dry mouth.
How Much to Take
I was not able to come up with a specific dose of Chasteberry for PMS symptoms. Additionally, there are different preparations of Chasteberry which makes dosing recommendations even more difficult. An often quoted dose of the Chasteberry fruit extract is 20mg to 40mg daily. While as little as 4mg of the standardized extract have been used in trials. So you may have to experiment a bit with a dose that works for you.
Bottom line is that Chasteberry looks promising for PMS as well as proving to be very safe. It’s probably worth a shot but you will want to make sure your not taking any dopaminergic drugs first.
