I need to know if this stuff

http://www.coleparmer.com/catalog/product_view.asp?sku=8809762&pfx

is safe for human consumption.  Camphoric acid is supposed to stop sweating in wasting conditions.  I had a sympathectomy and can't go outside in the summer without looking like I climbed out of a pool in 20 minutes.  

There is a website with almost 700 members that have had this done to them.  It's terrible.  We're looking for some kind of relief from our side effects.  

Thank you for your time.
