Where does the agnocast grow?

The agnocastus is native to Southern Europe and Southeast Asia. It is a shrub capable of reaching between 1 and 5 m in height. Its flowers are purple. Agnocastus grows in warm and temperate regions.


– Agnocastus has been used for thousands of years to cure different gynecological disorders, having been especially recommended by the famous Greek physician Hippocrates.

– Bearing in mind that about 70% of women of childbearing age would eventually suffer from menstrual cramps, agnocasto can be an effective alternative in curing this problem.


– Some clinical studies have shown the efficiency of agnocaste to alleviate some symptoms of premenstrual syndrome or PMS. It is a medicinal plant with proven efficacy against premenstrual syndrome, according to a special edition of the French journal Science & Vie published in July 2020 citing scientific studies and in particular meta-analyses. It is said that the iridoids and flavonoids, which are found in the plant, are at the origin of the favorable effects in women, by modifying certain hormonal reactions, in particular in the pituitary gland (in the brain), binding in particular to the dopamine D2 receptors .

– The fruits of the agnocastus resemble those of the pepper tree, with a black-grey color.

– The leaves of agnocastus slightly resemble those of hemp.
