Indigo Naturalis (Qing Dai): A Cooling Herb for Heat Toxins, Inflammation, and Skin Health
Introduction
Indigo Naturalis, known as Qing Dai (青黛) in Traditional Chinese Medicine (TCM), is a deep-blue powder derived from the leaves and stems of several indigo-producing plants, including Baphicacanthus cusia and Indigofera tinctoria. Beyond its historical use as a natural dye, Qing Dai is highly valued in TCM for its ability to clear heat, cool the blood, and reduce inflammation. It is cold and salty in nature, entering the Liver and Lung meridians.
What Is Indigo Naturalis?
Qing Dai is traditionally obtained by fermenting and processing indigo plant leaves until a fine blue powder forms. In TCM, it is used to clear toxic heat from the body, stop bleeding, and calm internal inflammation. It is especially favored for skin and respiratory conditions linked to heat and fire toxins.
