Modern Research Perspective

Indigo Naturalis contains indigo, indirubin, tryptanthrin, and other constituents. Experimental and clinical studies have explored inflammatory skin disease and immune pathways, but composition, dose, and safety vary.

Potential liver, kidney, gastrointestinal, and contamination risks require monitoring. Human evidence is indication-specific and does not justify unsupervised internal use.

Traditional Function

Indigo Naturalis is traditionally salty and cold. It is used to clear heat and toxicity, cool the blood, and address selected blood-heat or inflammatory skin and oral patterns. Its pigment preparation requires strict quality control.
