Calcium montmorillonite clay: a clinically oriented narrative review of emerging perioperative and supportive applications

Calcium montmorillonite (CMM) clay, a naturally occurring mineral-rich volcanic clay has garnered scientific attention for its detoxification properties, gastrointestinal (GI) support, skin benefits, and potential metabolic modulation. Recent advances in pharmaceutical-grade formulation and mechanistic understanding have renewed clinical interest in CMM as a low-risk, non-systemic adjunct in modern medical practice. General practitioners and surgeons may find it particularly useful as a safe adjunct in gut health, topical recovery, and inflammatory modulation. With supporting data from preclinical and clinical research, including studies on aflatoxin binding, microbiome modulation, and treatment of radiation enteritis and pediatric diarrhea, CMM represents a promising natural therapeutic mineral for integration into modern health protocols. This narrative review summarizes the biological properties, clinical safety, indications, and emerging efficacy data surrounding CMM, with a focus on potential perioperative and wellness applications.
