Chemical Constituents: The ethanol extract of the shade-dried
leaves of Aristolochia bracteolata Lam. was studied for its effect on
wound healing in rats, using incision, excision and dead-space wound
models, at two different dose levels of 400 and 800 mg/kg/body wt./day.
The plant showed a definite, positive effect on wound healing, with a
significant increase of the level of two powerful antioxidant enzymes,
super oxide dismutase and catalase, in the granuloma tissue.
