Indigowoad root, also known as Isatis Root, Isatidis Radix, or Ban Lan Gen, is a traditional Chinese medicinal herb widely used for its strong heat-clearing and detoxifying properties.
There are two main varieties:
Northern Indigowoad Root – the dried root of Isatis tinctoria (Cruciferae family).
Southern Indigowoad Root – the dried rhizome and root of Baphicacanthus cusia.
Both types are bitter in taste and known for their ability to clear heat, detoxify, prevent colds, soothe the throat, and support immune health. As a widely used herbal material, radix isatidis plant products play an important role in traditional medicine and modern herbal formulations.
