Re: Comfrey



I use comfrey tincture in conjunction with witch hazel & arnica for my 
bruise juice (which can only be used on unbroken skin due to the arnica). 
 It is my understanding that comfrey (or boneknit) should not be used 
internally...studies show that it contains pyrrolizidines which cause 
serious liver damage & cancer in laboratory animals.  This is 
particularly true of the young leaves of the plant.  Comfrey also 
contains allantoin which is used in a number of OTC crams & balms.  
Allantoin is especially good for cold sores (I use Herpecin-L lip balm 
myself).  The roots contain more than twice as much allantoin as the 
leaves and are thus used moreso than the leaves for wound treatment.
