Although it is written for humans rather than for ferrets this is a
resource which not only discusses uses but also discusses dangers of
an assortment of alternative medical approaches, and a number of the
considerations will extend across most or all mammals.  Just like any
standard medication used for a medical problem alternative meds also
carry their own set of risks.  Usually anything strong enough to heal
is also strong enough to harm if used wrong, or in the wrong doses, or
for the wrong length of time, or with the wrong medical conditions, or
along with the wrong other meds or supplements, etc.
 
Please, also look in resources like the FML and FHL Archives (See
addresses below my name.) since a number of herbs have been discussed
there in relation to how they act in ferrets -- for example Pau D'Arco
being too dangerous in ferrets and why, and licorice root's long known
history of cardiovascular damage and risks like thromboses (at times
confused with strokes in ferrets) and heart attacks (as well as other
risks) in mammals in general when used chronically or used wrong
otherwise.
