It appears a study has finally been done with proper controls and guess what?

That's right. It does nothing.

Echinacea didn't prevent a cold. Echinacea didn't ease symptoms.

Edited to add following quote:

The trial was large, randomized, blinded, involved several institutions, and used standard nasal viral challenge methods, Dr. Sampson noted.

That one's my favorite from the article.

While the study is cool and all, is it really worth 3 different threads on the Science board?

ETA: Well, 2 now that the other two were merged.

Sorry
