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.
