The use of plants for healing purposes has been predated long before the existence of modern medicine. Herbal plants have formed a fundamental source for conventional medicine in discovery of single ingredient medication, including aspirin (from willow bark), quinine (from cinchona bark), and morphine (from the opium poppy)......
Recent study conducted by renowned institute suggested that Vitex agnus castus (Vac.) may have a potential in decreased over production of testosterone on the male reproductive physiology.
Testosterone is a male steroid hormone played an important role in male reproductive organs and building bone and muscle mass as well as stimulating sexual desire in both sexes.

Recent study conducted by renowned institute suggested that Vitex agnus castus (Vac.) may have a potential in decreased over production of testosterone on the male reproductive physiology.
Testosterone is a male steroid hormone played an important role in male reproductive organs and building bone and muscle mass as well as stimulating sexual desire in both sexes.
In the study of hydroalcoholic Vac. extract (extraction by percolation technique) with the following doses: 65, 165, 265, 365 and 465 mg kg-', bromocriptine as a dopamine receptor agonist (5, 10, 20 mg kg(-1)) and haloperidol as a dopamine receptor antagonist (1, 1.5, 2, 2.5, 3 mg kg(-1)) injection male mice treated with chaste tree berry extract or combination of the extract showed a significant decrease of levels of testosterone in compared to other treatment groups.
Dr. Nasri S, the lead author said, ". LH and testosterone were measured by Radio Immuno Assay (RIA). LH and testosterone, showed significant decrease in bromocriptine group and haloperidol increased these hormones. Vac. extract decreased significantly the LH and testosterone levels. The coadministration of Vac. extract and bromocriptine decreased LH and testosterone".
The study also found that Vitex agnus castus extract influences the neurotransmiters such as dopamine in regualted LH and testosterone secretion.
In confirm to the efficacy of chaste tree berry in reduced testosterone production, Vitex agnus castus L. (Vit.) fruit extract with 1650 mg/kg tested on male mice model with the doses (65, 165, 265, 365, 465 mg/kg) injected intraperitoneally for 30 days in 5 groups of animals, all tested mice showed a decreased testosterone levels in dose depending manner.
The researchers also insisted that through the Radio Immuno Assay (RIA), Vit. fruit extract has an anti-androgenic effect and probably acts through the Hypothalamic-Pituitary-Gonadal (HPG) axis and the side effects only appear after a long time of their usage.
Dr Jillian Stansbury, not the author of the studies said, " (due to the effects of chaste tree berry in reduced LH levels and testosterone levels ) that Vitex may improve symptoms of high testosterone levels in men, including excessive libido, acne, and prostatic disease."
The reduced levels of testosterone of the herbal medicine may be beneficiary for patients with high levels of testosterone induced of sexual libido, acne and abnormal prostate expression.
