Dear Scott,
Although Schultz contributed, I obtained the info from a wide variety of
places.  I've been studying cayenne since 1991 when a friend showed me how
to eliminate the ouch from having hit my finger with a 28 oz. framing
hammer.  The pain went away in about a minute and I have been sold and
curious ever since.  I think I got a lot from Hienerman as well as Thomas.
I now have over 50 herbal references and wish I had more.  Unfortunately so
many of the authors are so afraid of the FDA police that they chicken out
when it comes to telling it like it is.  I try to look for books that are
either immediate post-WWII or pre-WWII.  I have access to Powells in
Portland, OR and that is one great source.  I think it covers a city block
and a few floors.  The herbal section alone is worth about 3 hours of look
time.

Hope I've helped
Jack
