Gastric antiulcer and anti-inflammatory activities of the essential oil from Casearia sylvestris Sw.

To investigate the antiulcer and antiinflammatory activities of the essential oil from Casearia sylvestris leaves (EOCS) the following tests were used: rat paw edema, granulomatous tissue test, vascular permeability, writhing test, gastric ulcer stress-induced and evaluation of gastric secretion (pylorus ligation test). The total yield of EOCS was 2.5% with LD50 of 1100 mg/kg in mouse.

Anti-inflammatory and analgesic properties of water-ethanolic extract from Pothomorphe umbellata (Piperaceae) aerial parts.

Anti-inflammatory and analgesic activities as well as the median lethal dose (LD50) of water-ethanolic extract (PHE) of the aerial parts of Pothomorphe umbellata were evaluated in animal models. The ED(50) (oral) for the inhibition of carrageenan-induced rat paw edema assay was determined to be 550 mg/kg, while the LD(50) was higher than 2.0 g/kg.
