Brazilian Green Propolis Displays Good Anti-Ulcer Activity

Effect of Brazilian Green Propolis on Experimental Gastric Ulcers in Rats
Journal of Ethnopharmacology, 2007 Apr 4;110(3):567-71. Epub 2006 Oct 28

Propolis is a resinous hive product collected by honeybees from plants. The propolis produced in Southeastern of Brazil is known as green propolis because of its color. Modern herbalists recommend its use because it displays antibacterial, antifungal, antiviral, hepatoprotective, anti-inflammatory, immunomodulatory and anti-ulcer properties. The anti-ulcer activity of green propolis hydroalcoholic crude extract was evaluated by using models of acute gastric lesions induced by ethanol, indomethacin and stress in rats…

Animals pretreated with propolis hydroalcoholic crude extract (50, 250 and 500mg/kg) showed a significant reduction in lesion index, total affected area and percentage of lesion in comparison with control group (p<0.05) in the ethanol-induced ulcer model. Green propolis extract, at a higher dose (500mg/kg), displayed a significant protection by reducing (p<0.05) the evaluated parameters in the gastric ulceration induced by indomethacin…

These findings indicate that Brazilian green propolis displays good anti-ulcer activity, corroborating the folk use of propolis preparations, and contributing for its pharmacological validation.
