Qing Dai Indigo Naturalis Powder 500g Ultra-Fine TCM Herbal Powder

Indigo Naturalis, known in TCM as Qing Dai (青黛), is a deep blue powder traditionally prepared from the leaves of Strobilanthes cusia, Baphicacanthus cusia, or related indigo plants. In TCM theory it is considered cold in nature and salty in flavor, traditionally associated with clearing heat. This ultra-fine powder is sold as a raw botanical for traditional herbal use and is not a substitute for medicine.

Traditional Uses

In TCM practice, Qing Dai has traditionally been used in external powders and pastes, often combined with other cooling herbs such as Huang Bai or Bing Pian for topical applications. It also appears in classical formulas where it is traditionally associated with clearing heat and calming. Because it is cold in nature, it was historically used in small amounts and rarely as a standalone daily herb.
