The most distinctive feature of Agnus Castus is that it has a positive rebalancing hormonal effect on the body, and specifically on the pituitary gland which this clever little herb nourishes, with evidence showing that it has proved effective for early stage cases of Cushing’s syndrome.
The UK Horse Journal ran a field trial of Vitex including 10 horses and ponies, the subjects aged between 13 and 25 years, diagnosed with Cushing's or demonstrating the classical Cushing's symptoms. The Journal reported that typical response was 'rapid and dramatic'. Shedding of the coat typically began within three weeks, and energy levels quickly increased. High blood glucose and insulin levels dropped in some cases within four to six weeks.
For our mares, Agnus Castus is helpful in easing mood swings, normalising hormone levels by lowering prolactin (the hormone released from the pituitary gland which stimulates the breast glands to produce milk) and raising progesterone levels to counterbalance the increase and effects of estrogen during estrous.
