RESUMEN
This study was carried on the Cichorium intybus Plant grown in Syria. We had investigated the active principles of this plant throughout some chemical tests. This plant was found to contains: Carbohydrates, glycosides, saponin, tannic acids, resins, and Lymphocytes and Monocytes were significantly higher [p<0.01], and decreased percentage of Hertophils. Alkaloides. It was also acidic in reaction. This study was planned to investigate: Toxicological studies of the methanolic extract of Cichorium intybus plant on white mice no deaths and would not determine the LD50 up to 1000 mg/kg. Experiment broiler chickens were divided into two groups, methanolic extract of Cichorium Intybus was given in concentration 10% to the first group in average 2 ml/liter of drinking water daily for 42 days, while the second group was kept as a normal group [control]. The obtained results showed that the addition of methanolic extract of Cichorium Intybus plant leads to increase in RBC, WBC, Hb, PCV and the percentage of
