ABSTRACT
The anti-ulcer effect of the aqueous extract of Matricaria chamomilla flowers (chamomile extract, CE)
had been tested on stress- ethanol induced gastric ulceration in rabbits. The first part of the study was to
induce acute gastric ulceration by stress or stress–ethanol combinations. Stress alone was unable to
produce gastric ulcerations while ulcer was induced in the group of rabbits exposed to stress in the
presence of ethanol (5ml / kg ) with a mean value of ulcer index of 108.3mm ± 29 (n=8). Histopathological
examination was done to confirm the effect of stress-ethanol combination on gastric mucosa. The second
part of the study was performed to investigate the pharmacological effect of various concentrations of
the aqueous extract of chamomile (1%, 4% and 8%) on gastric ulceration. The extract was given 15
minutes before ethanol administration. The results have shown a significant anti ulcer effect of
chamomile extract with mean values of ulcer index of 76. 4mm± 14.2 (P< 0.01); 11mm ± 14.2 (P<0.005)
and 53mm±27.9 (P<0.01) for the concentrations 1%, 4% and 8% respectively as compared to the control
value of 133.25 mm±46.2 (n=8). It is concluded that the extract of Matricaria chamomilla flowers has anti
ulcer effect.
