German researchers have suggested that an extract of Vitex Agnus Castus fruit, which is also known as chasteberry, has been shown to reduce the symptoms associated with premenstrual syndrome by around 50%.   It has been used for many years by herbalists and naturopaths to treat the symptoms of PMS and the results of the study are suggesting that it should now be considered by medical practitioners as an effective way to manage the condition.

(British Medical Journal; 2001; 322; pp 134-7)


  1. Can vitex be used to help with hot flashes and night sweats if I’ve had a hysterectomy?
    Maca, black cohosh, Chinese herbs/acupuncture, homeopathy and soy have not helped.

  2. The ancient Greeks used it to aid wound healing, spleen problems and also for child birth.On the otherhand with this agnus castus emphasis on long-term balancing of a woman’s hormonal system, it is not a fast-acting herb and is unlikely to give immediate relief to the discomfort associated with PMS or premenstrual syndrome. For premenstrual syndrome, frequent or heavy periods, agnus castus can be used continuously for four to six months or as prescribed by your physician.Thus, self medication is not recommended!

  3. It has been used in herbal medicine for thousands of year as anaphrodisiac herb and is considered as Queen herb in treating menstrual problems and discomforts by taking it in a prolonged period of time.

  4. I am a 51 year old woman, and noticed 4 years ago an increased flushing, slight sweating (and as I had experienced severe anxiety due to a stressful situation), this was making me more despondent. I went to see my doctor who recommended Agnus Castus and had been taking it for 2 years. I found the effects fabulous, and had no problems with it.

    On 3rd Nov 2010 I went for my first mamagram, and was recalled as they had found a lump. I have no breast cancer in my family, socially smoker only, and yes had been a heavy drinker in the past but only socially, and had breast feed two children.

    A biopsy revealed a Grade 1 ductual cancerous 5mm lump, and also a 4mm atypical ductual cell non cancerous. I was operated on 2 weeks later and the tests revealed that there was no trace of cancer cells around the lumps or to the lyphm nodes.

    I have read in research that Agnus Castus should not be taken by lactating or pregnant woman, does this mean that this herb affects the duct glands or just the hormone levels.

    I would like some more information on this.

    Many thanks
