Vitex agnus

Vitex agnus or Chaste Berry

Vitex agnes grows well in warm temperate climates and may be grown successfully in the North Island, New Zealand. We now have several mature bushes that are fruiting. Parts used are the berries though leaves can be used as well. The image above has been taken at our place. the plant is around 5 years old and is finally fruiting. We have around 10 plants grown for experimental purposes.

Agnus castus has been used for thousands of years for its beneficial affect on the female hormonal system. The seeds and fruits are anaphrodisiac, aphrodisiac, galactogogue, ophthalmic, sedative, stomachic, women’s complaints. The berries of this plant have a range of medicinal actions but possibly the most important is its ability to rectify hormonal imbalances caused by an excess of oestrogen and an insufficiency of progesterone. It acts upon the pituitary gland, reducing the production of certain hormones and increasing the production of others, shifting the balance in favour of the gestagens.

Vitex agnes has a wide application of uses in malfunctions of the feminine reproductive system and has been used with great effect in restoring absent menstruation, regulating heavy periods, restoring fertility when this is caused by hormonal imbalance, relieving pre-menstrual tension and easing the change of the menopause.

Active Ingredients 

Flavonoids,, alkaloids, diterpenoids, vitexin, casticin and steroidal hormone precursors have been isolated from the chemical analysis of Vitex agnus-castus. It is believed that some of these compounds work on the pituitary gland which would explain its effects on hormonal levels. A study has shown that extracts of the fruit of VAC can bind to opiate receptors; this could explain why intake of VAC reduces PMS discomforts.

• May help with PMT and insulin fluctuations associated with prementrual tension.
• Improves female libido while in some cases seems to suppress male libido by inhibiting production of dopamine.
• The berries are considered to be an aphrodisiac, though other reports say that they are anaphrodisiac. The reason for this apparent disagreement is that the berries have a regulating effect on the body and so are likely to increase sexual activity in those who are not very active in this area whilst reducing it in those who are very active.
