Ingredient Profile & Common Uses
Ban Lan Gen refers to the root material associated with Isatis indigotica and the pharmacopoeial name Isatidis Radix. It is distinct from Isatis leaf-derived ingredients and indigo-rich preparations, which use different plant parts and chemical profiles. It should also not be confused with Nan Ban Lan Gen from Strobilanthes cusia (syn. Baphicacanthus cusia), a separate botanical raw material.
Ratio extracts form the main commercial grade structure. The 10:1 grade is the principal sourcing format, while 20:1 provides a more concentrated secondary option. These ratios describe botanical extraction concentration rather than the amount of an individual compound, so marker-controlled material requires a separate analytical definition rather than assuming that a higher ratio corresponds directly to higher marker content.
The root contains glucosinolates and goitrin-related compounds together with nucleosides, alkaloids, lignans, organic acids, amino acids, and polysaccharide fractions. This multi-component chemistry distinguishes the extract from purified single-compound materials. In formulation, the concentrated botanical matrix can influence powder handling, sensory characteristics, and dispersion behavior.
