Piper margintum, in the Piperacea family is a native and endemic plant in Brazil. It is
an important plant used medicinally in South and Central America. The most common
use of Piper marginatum is related to gastrointestinal diseases. The aim of this study
was to evaluate the possible gastroprotective and antiedematogenic effects of Piper
marginatum Essential Oil. For antiedematogenic effect was used the ear edema
induced by Phenol. For the gastroprotective effect was used the gastric injury induced
by acified ethanol and Indomethacin. It was observed after 1 hour of edema induction,
the OEPM inhibited edema both at the dose of 1000 mg / kg (55%) and 500 mg / kg
(42%) when compared to the Phenol group. In the acidified acid-induced gastric injury
test, the OEPM showed a lower percentage of ulcerated area at the doses of 1000mg
/ kg (7.90%) and 500 mg / kg (8.41%), when compared to the control group (17.92%).
In the indomethacin-induced gastric test, a lower percentage of ulcerated area was
observed in the groups which received the OEPM; however, there was no statistically
significant difference at 1000 (9.02%), 500 (11.61%) and 250 mg / kg (15.08%), when
compared to the control group (16.92%). The results presented in this study showed
the OEPM has active compounds with gastroprotective and antiedematogenic effects.
