In a world dominated by pills and synthetic supplements, white clay is an ancestral remedy that is regaining attention due to its scientifically proven effectiveness in supporting the digestive tract. Used internally, in a mixture with water, white clay is a true natural dressing for an irritated stomach, increased acidity, or bloating.
What is White Clay (Kaolin)?
White clay is a type of clay rich in silica and mineral salts, with a fine texture, purified and non-toxic, specifically intended for internal consumption.
Scientific name: Kaolinum
It is obtained by grinding sedimentary rocks, being free of irritating substances.
Active Chemical Composition
- Silica – soothes mucous membranes and promotes regeneration.
- Calcium, magnesium, iron, potassium – balance intestinal flora.
- Alkaline pH – neutralizes excess gastric acid.
What Do Studies Say?
International Journal of Toxicology (2020): the consumption of pharmaceutical white clay, in controlled doses, reduced digestive discomfort by 68% in patients with irritable bowel syndrome or increased acidity.
Pharmaceutical Biology (2019): white clay acts as an absorbent agent that binds toxins, bacteria, and excess acid, protecting the gastric mucosa.
How Does It Work in the Stomach?
Soothes irritated mucosa.
Binds excess bile and gastric acids.
Absorbs gases and toxins.
Regulates intestinal transit (mild laxative or mild astringent, depending on the dose).
