Pearl-layer powder

Ingredient Profile

Modern Research Perspective

Pearl-layer powder contains calcium carbonate, trace minerals, and protein or peptide fractions. Experimental studies have explored mineral, bone, antioxidant, and wound-related mechanisms, but composition depends on source, particle size, and purification.

Human clinical evidence for a standardized single material is limited. Contaminant testing, mineral exposure, gastrointestinal and renal safety, dose, and long-term outcomes require further evaluation.

Traditional Function

Pearl-layer Powder is traditionally sweet and salty with a cold nature. It is used to calm the spirit, improve vision, clear heat, and support skin or tissue repair in selected patterns. The shell layer and processing are part of medicinal identity.
