Cons: Not very concentrated
The back of the bottle says that it's recommended to take 3 capsules three times every day (with two weeks off every 1.5 or 2 months). That's an awful lot of echinacea. I certainly don't take it that frequently. I do try to hit the bottle any time I'm feeling at all under the weather. But even then I don't usually manage to take 9 capsules a day...because...that's a lot. And I forget.
In any case, I usually get the Echinacea Purpurea (which is the stem, leaf, and flower apparently). It seems to help with the onset of colds (although it's usually only one part of my arsenal of Emergen-C and AirBorne, etc.) Overall, I'd say I'd get this type of echinacea again..but I might look for one that's a little more concentrated.
