Wintergreen, I've heard of people absorbing aluminium from Bentonite clay....don't know whether the same applies to pascalite.

Also in "Optimum Nutrition for the Mind", Patrick Holford states that calcium is good for keeping aluminium (and cadmium) levels down. He also said it's poorly absorbed into the body unless you're zinc deficient.
