Re: terramin clay ...18.3 % aluminum

relax. All bentonites and montmorillonites are aluminum silicates. The aluminum is atomically bound to the silicate. It cannot be digested, and it cannot harm you.

Terramin clay actually pulls heavy metals and pathogenic toxins out of your body, while it provides you with trace minerals needed for optimum health.

All of this is vetted on the internet. The FDA says this class of clay minerals is safe, and there are no indications of any kind of toxicity or allergies. Most people find that it detoxifies and remineralizes like no other substance. Good for people and animals.
