The main objective was to evaluate the sedative effect of the Tl extract. Therefore, the tests were realized using
the dose(s) lower than the LD50―in order to make use of a dosage that does not cause death―and 5 lots consisting

Afterwards, the sedative effects of the ethylic ether extract were verified and outlined by performing the following
tests on the groups of rats:
