French green clay is also good for detoxification.  See: http://www.frenchclayforall.com/info.html

You can get French Green Clay in the bulk herbs area of most health food stores.  Here is some info. regarding its ability to detoxify:

The degree of the adsorbing power of this clay is another key to its wonderful healing abilities.

Let's keep things simple enough to understand...

Absorption of the impurities in the tissues, neutralizing and draining these impurities.. extra cellular level.

Adsorption means the pulling out of the impurities that are in a state of suspension in the body liquid (blood, lymph, bile) and then draining and eliminating them... Intra cellular level.

Clay considerably reduces the toxicity of harmful substances.

A famous incident that happened in France in which many dogs have been poisoned, but survived, thanks to the clay which had been put in their drinking water.

According to Dr Camberg ( a European doctor), clay takes care of any poisoning, even such as arsenic! One teaspoon of clay mixed in a glass of water every hour for 6 hours to be out of trouble.

As with all natural remedies, clay does not act specifically on one or several bacteria varieties; rather it prevents their proliferation by reinforcing the defenses of the organism.

Contributing to the elimination of acids, clay favors a good pH of the blood.

This wonderful adsorbing power has a magnet effect.

For healing and therapeutical purposes, this clay may be used externally and orally.

Eating clay can be a wonder-working cure!

Applied in poultices and compresses, clay provides numerous benefits.

It can heal sores and ulcers and aid in the rebuilding of healthy tissues and cells, and even of fractured bones and vertebrae.

Everything unhealthy and emiting negative radiations is irresistibly attracted to clay ( a brilliant positive pole) and becomes subject to immediate elimination.

Wherever there is a deficiency, clay seems to supply the needed substance regardless of whether or not the clay itself is rich in that substance.
