Baptisiae tinctoriae radix

Extract from the root of the dyer's tube.

According to the current state of knowledge, various polysaccharides (heteropolysaccharides), especially arabinose and galactose, are considered to determine the efficacy of arabinogalactan proteins, which also occur in Echinacea angustifolia, the narrow-leaved coneflower.

The ingredients of the dyer's legume root are said to have immune-strengthening effects. Extracts of the dyer's husk root have so far been used in combination with other plants(Echinacea angustifolia and Esberitox N®). In this combination the active ingredient is said to improve the body's own defence reaction.

An official medical evaluation of the national societies for phytotherapy(ESCOP and Commission E) is not yet available for the dyer's husk root due to insufficient scientific knowledge.
