Sonne’s #7 Detoxificant contains Bentonite, the mineral-rich volcanic clay mentioned above. However, through a refining process that removes mica, dirt, and impurities, Bentonite is reduced to its active detoxifying ingredient, Montmorillonite. This refining process is “exclusive and secret,” according to the product website. The description simply indicates that, when it’s all said and done, the purified Montmorillonite is put in a liquid colloidal-gel state, sterilized, and subjected to lab tests that ensure it is suitable for consumption. As an indication of the absorptive powers of Bentonite/Montmorillonite, Sonne’s only packages their #7 Detoxificant in glass bottles, as the Montmorillonite can leach petrochemicals from plastic bottles. Consumers ought to be wary of any other Bentonite detoxification products that are packaged in plastic.
