Ingredient Profile & Common Uses
The raw material is the mature seed of Lablab purpureus (L.) Sweet. Bai Bian Dou is the traditional Chinese ingredient name, while Semen Lablab Album appears in traditional crude-drug terminology. Older medicinal and trade references may use Dolichos lablab L. This ingredient should not be confused with white kidney bean extract from Phaseolus vulgaris, which is a different botanical species and commercial ingredient.
Commercial grades are differentiated primarily by extraction ratio rather than by a universally adopted marker-compound assay. The 10:1 grade represents the main sourcing specification, while 4:1 and 5:1 provide lower concentration ratios and 20:1 provides a higher ratio option. Buyers therefore compare the material primarily by botanical identity, plant part, extract ratio, and identification method.
The concentrated powder is used in dietary supplements, traditional plant-based combinations, powdered nutrition products, and selected functional formulations. Compared with whole-seed powder, ratio extracts allow formulators to introduce concentrated seed material at a lower ingredient loading. Important development considerations include natural color, botanical taste, dry-blend distribution, powder flow, and dispersion behavior in the finished formulation.
