Standard Process's Echinacea Premium is the best one I've found.
The tablets combine the 2 most active strains, Echinacea purpurea, and Echinacea angustifolia, both of which work better in combination than they do alone. The two species are combined because the two together form a protective chemical bond that prevents breakdown in the liver, which would otherwise render the product far less effective.
A bottle of 40 tablets is $32.50.
--Take one tablet daily to prevent infections all winter.
--Take one tablet twice a day if you think you might have been exposed but are still feeling okay.
--Take one tablet every 2 hours if you feel yourself getting sick!
