Aloe for Rheumatoid Arthritis & Stomach Ulcers?

I have heard about aloe vera pills/gel used to aid in above conditions. Can you suggest where I may find more info on aloe? I am currently on meds for these conditions.

Dr. Andrew Weil lists an excellent protocol for ulcers, including the use of aloe, on his website at www.drweil.com/drw/u/id/QAA352656.
There is a good history of the medicinal use of aloe, including modern uses at www.1st-aloe-vera.com/aloe-history.htm.
