Abstract
The present work was performed to study the effect of Astragalus
membranaceus and Echinacea purpurea on haematology, biochemistry
and immunity of healthy albino rats. The study included two experiments.
The first one comprised 36 rats subdivided into four groups. Each group
was consisted of nine rats. The first group received daily oral
administration with 0.25g/kg/day of Astragalus membranaceus for two
and four weeks, the 2nd group received daily oral administration of
O.5g/kg/day of Astragalus membranaceus for two and four weeks, while
the 3rd group received daily oral administration with 1.0glkg/day of
Astragalus membranaceus for two and four weeks, the 4th group kept as
control. The second experiment consisted of 36 rats subdivided into four
groups. Each group was consisted of nine rats. The first group received
daily oral administration 0.25g/kg/day of Echinacea purpurea for two and
four weeks, the 2nd group received daily oral administration with
O.5g1kg/day of Echinacea purpurea for two and four weeks, while 3rd
group received daily oral administration with 1.0g/kg/day of Echinacea
purpurea for two and four weeks, the 4th group kept as control
Results of the first experiment revealed that the daily treatment of
rats with Astragalus membranaceus doesn’t give any clinical signs and
mortalities rate
Regarding the blood picture, all Astragalus membranaceus
concentration 0.25g, 0.5g and 1.0g had no significant effect in all studied
parameters (total and differential leucocytic count) along the
experimental periods.
