Inhibition of human basophil degranulation by successive histamine dilutions:

I recently finished reading a homeopathy study titled "Inhibition of human basophil degranulation by successive histamine dilutions"

While superficially interesting, the human basophil degranulation test used in that study is a test tube test. It's not a human or even animal trail. Homeopaths can use special pleading all they want but a test tube trial is not how real pharmaceuticals get approved for sale.

I'm STILL looking for homeopathy related, double blind, placebo controlled human trials with a non-trivial sample size that demonstrate a statistically significant effect. Is EVERYTHING homeopaths have really just test tube studies that haven't been replicated?
