Introduction: In Cuba and Caribbean countries Hibiscus rosa-sinensis are very common in garden. Reports of traditional use are related with conjunctivitis, fever, headache, flu and cough. Our aim was to determinate preclinical anti-inflammatory, analgesic and antipyretic effect of decoction of leaves and flowers of H. rosa. Material and Methods: Activity was assayed on acute inflammation model (ear edema test), applying 10 µL croton oil, 75 µg/per ear. Different doses of decoctions 30% of flowers and leaves were evaluated topically and orally; 10 µL of decoctions were applied at each side of the treated ears. Model of analgesic was writhing test (acid acetic 0.75 %, 0.1 mL/10 g i.p) and tail flick test (water at 55°C). All experimental models was conducted in male OF-1 mice (20–25 g). Finally antipyretic activity was tested inducing pyrexia with brewer’s yeast (15% in water; 1 mL/100 g, sc.) in male Wistar rats (180-200g). Results: The extracts from leaves and flowers (30%) applied topically inhibited inflammation on 54.7% and 30.9% respectively. Orals administrations do not showed a significantly antiinflammatory activity in both extracts, but they have a significant anti-nociceptive response to thermal stimulus compared to control group. Decoctions of H. rosa significantly decreased the number of abdominal stretching in all cases. Only decoction of flowers showed a significant antipyretic activity similar to paracetamol, from the 1fts hour to 4 h after administration. Conclusions: Results validated traditional use of leaves or flowers of Hibiscus rosa sinensis in inflammation, flu, cough and pain process.
