Preclinical anti-inflammatory effects of dry powder of calendula officinalis

Preclinical Anti-Inflammatory Effects of Dry Powder of Calendula officinalis. With the objective to demonstrate the anti-inflammatory effect of Calendula officinalis dry powder, doses of 50, 150 and 450 were used on inflammation induced by carragenin, dextran, histamine and serotonine, the granulome induced by cotton pellets in rats and ear inflammation induced by croton oil in mice. The spray dried powder of Calendula officinalis inhibited the inflammatory process in all animal model employed without affecting tymus's and adrenal's weight. These results show that the powder of Calendula officinalis obtained by spray drying is active in inflammatory processes of diverse nature.
