Notes

The processed leaves yield Natural Indigo, known as Qing Dai.
Its most common use is to reduce maculae in acute infectious disorders.
It is typically taken in powder or pill form.
Indirubin, used in cancer treatment, is derived from Indigo. Studies indicate it works well against chronic myelocytic leukemia while producing few side effects.
Mildly toxic, it is frequently applied externally for skin conditions.
It clears Heat Toxin from the Heart, Lung and Stomach, and moves both the Qi and Blood Levels.
It is applicable to Heat-induced encephalitis and inflammation of the spinal fluid.
It may be given both internally and applied externally.
It can address Gallbladder Heat.
It resolves sores stemming from childhood malnutrition and from weapon poisoning.
Da Qing Ye, Indigo Naturalis (Qing Dai) and Rx. Isatidis (Bei Ban Lan Gen) all come from the same plant source; together they cool Blood Heat and reduce skin blotching. Qing Dai is the preferred choice for toxic sores from Fire and Heat, rashes from Warm-toxin, hemoptysis, hematemesis and childhood convulsions. Da Qing Ye and Bei Ban Lan Gen both cool Heat toxin affecting the Heart and Stomach, though Da Qing Ye is typically chosen for Warm-toxin rashes, while Bei Ban Lan Gen addresses severe head-region febrile disorders and throat obstruction caused by mumps.
