+A polysaccharidic fraction (EPF) obtained from Echinacea angustifolia roots inhibited carrageenan-induced paw oedema. "... furthermore, EPF, topically applied, inhibited mouse ear oedema induced by croton oil. EPF also reduced the leukocytic infiltration of the croton oil dermatitis, evaluated both as peroxidase activity and histologically. After topical application EPF appears to be slightly inferior in potency to indomethacin. The results suggest that the anti-inflammatory activity of E. angustifolia resides in its polysaccharidic content." \\

+The roots contain unsaturated alkylamides like undeca-2Z-en-8,10-diynoic acid isobutylamide, dodeca-2E-en-8,10-diynoic acid isobutylamide, undeca-2Z-en-8,10-diynoic acid 2-methylbutylamide, dodeca-2E-en-8,10-diynoic acid 2-methylbutylamide, hexadeca-2E,9Z-dien-12,14-diynoic acid isobutylamide and dodeca-2E,4Z,10Z-trien-8-ynoic acid isobutylamide. \\

+"It is generally thought that no single constituent or group of constituents is responsible for the activities of echinacea. Rather, several groups of constituents (the alkamides, caffeic acid derivatives, polysaccharides and alkenes (such as polyenes)) appear to contribute to activity. However, it has been reported that following
+oral administration in man, alkamides are bioavailable, whereas caffeic acid derivatives are not and, therefore, cannot contribute to activity..." \\
