A research team at the College of Science at the University of Basrah, consisting of Dr. Karim Hilal Thamer, Dr. Sahar Abdul-Abbas Malik, researcher Shaima Ibrahim and Dr. Mushtaq Talib Abdul-Mahdi from the Veterinary Hospital, obtained a patent to use the alcoholic extract of walnut bark by oral dosing on pregnant female white mice
The patent included the manufacture of an extract capable of abortion and the lack of birth rate in experimental animals. Through the biochemical study of animal serum, it was found that there were changes in the levels of estrogen and progesterone hormones in the blood of female mice, represented by a significant increase in estrogen
The histological study of uterine and ovarian sections of females treated with the extract showed several changes, including signs of bleeding and blood congestion in the tissue, in addition to failure in organ function, as well as an inflammatory response
