Emma, I ordered mine recently, I ordered all these:-
I ordered the Chuan Xin Lian Pian assuming it was the one.

You can get the Eclectic institute goldenseal from iherb.

The #2 after the Gan Mao Ling just means its Bomamed own brand.
Hope this helps

Hi Emma,
You're talking to the reigning uti queen of the ICAMA world right now!  (Hope to relinquish my title soon...) Gan Mao Ling on the Bomamed site is the same thing as Gan Mao Ling #2.  I think they used to distinguish but have not for several years now. 
 
If you're ordering from Bomamed anyway, you can get Dianthus and Chuan Xin Lian from them, but their prices are considerably steeper than other places on the web.  Other sites I've used include:
 
Pharmaca.com - for cxl
Naturalnutritionals.com - for dianthus
Chineseherbsdirect.com - for cxl
Maxnature.com - for dianthus - but they are VERY SLOOOW about getting it to you. 
 
I'd also advise getting several bottles of each thing.  Matia has had me on such a high amount of the herbs that I go through a bottle every 4 days.  I ran out right at the beginning of the uti mess because it was over Thanksgiving and the shipping times were all wacky. 
Hope that helps!
