             Echinacea purpurea contains so-called
             polysaccharide compounds that are

             have attempted to test the herb as a
             treatment for the common cold and the
             results are decidedly mixed. A large
             study in 2007, for example, found that

             infections and your chances of catching
             a cold. Meanwhile, two other studies

             found no benefit.
