Ban Lan Gen Extract (Isatis Indigotica Extract)
Ban Lan Gen Extract, derived from the roots of the distinct *Isatis indigotica* plant, is standardized to contain specific levels of active Indirubin and Indole compounds. It is celebrated for its powerful ability to clear heat, detoxify the blood, and support deep immune resilience, making it a foundational botanical for seasonal health and defense formulations.
What is Ban Lan Gen Extract?
Ban Lan Gen Extract is sourced from the dried roots of the premium botanical Isatis indigotica Fort. Known traditionally as Ban Lan Gen, it is one of the most prominent herbs in Chinese medicine for immune defense. Unlike standard powders, it is rich in key active compounds including Indirubin, Indigo, along with other specific alkaloids, polysaccharides, and antioxidants. The extract typically appears as a brownish-yellow fine powder and is standardized to guaranteed levels (ranging from specific alkaloid content or a specific ratio like 10:1 TLC).
Revered as a premier botanical for seasonal defense, Ban Lan Gen is traditionally used to treat acute challenges, soothe the throat, manage heat-related imbalances, and clear internal and blood stagnation. As a professional Ban Lan Gen Extract supplier, we ensure rigorous quality control to deliver a pure, potent ingredient suitable for seasonal health, daily immune defense, and traditional wellness formulations.
