Oh my, so that had nothing to do with echinacea per se, and everything 
to do with a grotesque overdosing leading to long-term proving!!!  
Please don't blame if on that friendly little herb...   

  I'm so 
glad you've been able to put him right, poor guy!
But I would *love* to read whatever you're able to tell us about his 
symptoms when you first began working with him, and more about what 
happened over time, whatever you remember?  "Silent aggressions in his 
movings, his speakings, although he tried to be nice..."
There are only about 60 rubrics for echinacea in my rep, and it does 
not look like a happy picture.  I wonder whether his experience 
suggests any additions?
