Serena,
 
I've never had this problem with a ferret, most of mine have had the
adrenal and three with insulinoma.  This is how I found this site,
http://www.newrainbowbridge.com/essiac.htm.
 
Click on it and go down to "Our Personal Experience with Essiac".  I don't
know if this really works, but I've been dealing with their Devil's Club
Supreme for insulinoma and it has worked.  You might give Steve or Diane a
call and talk with them about Essiac.
 
Hope this will help you.
