Baptisiae tinctoriae radix

Extract from the root of the dyer's pod (wild indigo).

According to current knowledge, various polysaccharides (heteropolysaccharides), especially arabinose and galactose as a component of arabinogalactan proteins, which are also found in Echinacea angustifolia, the narrow-leaved coneflower , are considered to be effective.

Isoflavones (baptigenin, pseudobaptigenin) and their glycosides (baptisin, pseudobaptisin, trifolirhizin), the alkaloids cytisine, methylcytisine, coumarins as well as polysaccharides and various glycoproteins.

The ingredients of the dyer's legume root are said to have immune-boosting effects: positive influence on the phagocytosis activity of Kupffer's stellate cells. Extracts of the dyer's legume roots have been used in combination with other plants(Echinacea angustifolia and arborvitae tips - Esberitox N®). In this combination, the active ingredient is said to improve the body's own immune response.

An official medical evaluation of the national societies for phytotherapy(ESCOP and Commission E) has not yet been carried out on the dyer's pod root due to insufficient scientific knowledge.
