against M. tuberculosis and Staph aureus in vitro and other
bacteria and fungi. Eugenol and methyleugenol showed a positive
activity. Adaptogenic (antistress) activity has been found in
mice and rats. The plant increased the physical endurance and
prevented stress-induced ulcers. In general pharmacology the
aqueous extract showed hypotensive activity and inhibited the
smooth muscle contraction induced by acetylcholine, carbachol
and histamine. It also potentiated the hexobarbitone sleeping
time. Protective action against histamine-induced bronchospasm
has been shown in animals.
