how do you prepare peyote?

I may have a living, 15 year old cactus soon, and I want to know how to prepare and consume the mescaline. Also, is it possible to keep re-using it if I don't completely cut it to shit and kill it?

Iv heard you can just pick the buttons off grind them up and eat them for the mesculine experience (apparently the american indians used to do it)but of course its not pure mesculine. That way you dont destroy the plant at least.
