There is an inherent risk of contamination for a number of herbs, not 
just gotu kola.  Huperzine A, for example, is a compound extracted from 
Huperzia serrata.  However, a number of Huperzine A supplements on the 
market do not merely contain huperzine A, but also an array of crude 
extracts of the moss which are potentially toxic.  (Note, however, pure 
Huperzine A has been shown to be non-toxic even at doses 100 times the 
therapeutic dose).  Thus, unless you are completely confident that the 
supplement you are ingesting is of high quality (i.e. > 99% pure), 
proceed with caution – since even minuscule amounts of impurities can 
produce significant detriment with chronic usage.

Take care John.
